PROSPECTUS May 1, 1998

CALVERT CAPITAL ACCUMULATION FUND
CALVERT NEW VISION SMALL CAP FUND
4550 Montgomery Avenue, Bethesda, Maryland 20814

Calvert Capital Accumulation Fund seeks long-term capital appreciation by
investing primarily in the stock of medium-sized companies using the talent of
one or more investment subadvisors. The market capitalization of companies
chosen for investment will generally be within the range of capitalization of
the S&P 400 Mid-Cap Index, but the Fund may also invest in larger and smaller
companies as deemed appropriate. It is the Advisor's intent that on average,
the market capitalization of the companies represented in the Fund's portfolio
will be mid-sized, with a slight bias toward the growth-style of investing.
Other investments may include foreign securities, convertible issues, and
certain options and futures transactions. The Fund will take reasonable risks
in seeking to achieve its investment objective.

Calvert New Vision Small Cap Fund seeks to achieve long-term capital
appreciation by investing primarily in the equity securities of small
companies (currently those with a total capitalization of less than $1 billion
at the time of the Fund's initial investment) publicly traded in the United
States. In seeking capital appreciation, the Fund invests primarily in the
equity securities of small capitalized growth companies (including American
Depositary Receipts ("ADRs")) that have historically exhibited exceptional
growth characteristics and that, in the Advisor's opinion, have strong
earnings potential relative to the U.S. market as a whole. The Fund employs
aggressive investment strategies that have the potential for yielding high
returns. The Fund will take reasonable risks in seeking to achieve its
investment objective.

Share prices of both Funds may experience substantial fluctuations so that
your shares may be worth less than when you originally purchased them. Income
is not an objective of either Fund; the Funds should not be used to meet
short-term financial needs. There can be no assurance that either Fund will be
successful in meeting its investment objective.

Responsible Investing

To the extent possible, investments are made in enterprises that make a
significant contribution to our society through their products and services
and through the way they do business.

Purchase Information

The Funds both offer three classes of shares, each with different expense
levels and sales charges. You may choose to purchase (i) Class A shares, with
a sales charge imposed at the time you purchase the shares ("front-end sales
charge"); (ii) Class B shares, which impose no front-end sales charge, but
will impose a deferred sales charge at the time of redemption, depending on
how long you have owned the shares )("contingent deferred sales charge," or
"CDSC"), or (iii) Class C shares which impose no front-end sales charge but
will impose a CDSC on shares purchased after May 31, 1998, if they are sold
within one year. Class C shares are not available through all dealers. Class B
and C shares have a higher level of expenses than Class A shares, including
higher Rule 12b-1 fees. These alternatives permit you to choose the method of
purchasing shares that is most beneficial to you, depending on the amount of
the purchase, the length of time you expect to hold the shares, and other
circumstances. See "Alternative Sales Options" for further details.

To Open An Account

Call your investment professional, or complete and return the enclosed Account
Application. Minimum initial investment is $2,000 (may be lower for certain
retirement plans).

The example should not be considered a representation of past or future
expenses. Actual expenses and return 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
would bear directly (shareholder transaction costs) or indirectly (annual fund
operating expenses).

A.    Shareholder Transaction Costs
are charges you pay when you buy or sell shares of the Fund. See "Reduced
Sales Charges" to see if you qualify for possible reductions in the sales
charge. 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 fiscal 1997 historical expenses, except for Class B of the
Capital Accumulation Fund and the New Vision Small Cap Fund. Management fees
are paid by the Funds to the Advisor for managing the Fund's investments and
business affairs. Management fees include the subadvisory fees paid by Calvert
Asset Management Company, Inc. (the "Advisor") to the various subadvisors and
the administrative service fee paid to Calvert Administrative Services
Company. Management Fees have been restated to reflect expenses anticipated in
the current fiscal year. (See "Management of the Fund") The Management fees
for the Capital Accumulation Fund are subject to a performance adjustment
which could cause the fee to be as high as 0.95% or as low as 0.65%, depending
on performance. The Funds incur Other Expenses for maintaining shareholder
records, furnishing shareholder statements and reports, and other services.
Management Fees and Other Expenses have already been reflected in the Funds'
daily share price and are not charged directly to individual shareholder
accounts. Please refer to "Management of the Fund" for further information.
The Advisor may voluntarily defer fees or assume expenses of the Funds. The
respective Investment Advisory Agreements provide that the Advisor may, to the
extent permitted by law, later recapture any fees it deferred or expenses it
assumed during the two prior years.

The Funds' Rule 12b-1 fees include an asset-based sales charge. Thus,
long-term shareholders in each Fund may pay more in total sales charges than
the economic equivalent of the maximum front-end sales charge permitted by
rules of the National Association of Securities Dealers, Inc. In addition to
the compensation itemized above (sales charge and Rule 12b-1 service and
distribution fees), certain broker/dealers and/or their salespersons may
receive certain compensation for the sale and distribution of the securities
or for services to the Funds. See the SAI, "Method of Distribution."

INVESTMENT OBJECTIVE AND POLICIES

Capital Accumulation Fund

The Capital Accumulation Fund seeks to provide long-term capital appreciation
by investing, under normal market conditions, at least 65% of its assets in
the equity securities of mid-sized companies. It invests primarily in a
nondiversified portfolio of the equity securities of mid-sized companies that
are undervalued but demonstrate a potential for growth. The Fund will rely on
its proprietary research to identify stocks that may have been overlooked by
analysts, investors, and the media, and which will generally be within the
range of capitalization of the S&P 400 Mid-Cap Index, but which may be larger
or smaller as deemed appropriate. Investments may also include, but are not
limited to, preferred stocks, foreign securities, convertible securities,
bonds, notes and other debt securities. The Fund may use certain futures and
options, invest in repurchase agreements, and lend its portfolio securities.
The Fund will take reasonable risks in seeking to achieve its investment
objective. There is, of course, no assurance that the Fund will be successful
in meeting its objective since there is risk involved in the ownership of all
equity securities. The Fund's investment objective is not fundamental and may
be changed without shareholder approval. The Fund will notify shareholders at
least thirty days in advance of a change in the investment objective of the
Fund so that shareholders may determine whether the Fund's goals continue to
meet their own.

New Vision Small Cap Fund

The Calvert New Vision Small Cap Fund seeks to provide long-term capital
appreciation by investing primarily in equity securities of companies that
have small market capitalizations. In seeking capital appreciation, the Fund
invests primarily in equity securities of small capitalized growth companies
that have historically exhibited exceptional growth characteristics and that,
in the Advisor's opinion, have strong earnings potential relative to the U.S.
market as a whole. The Fund's investment objective is not fundamental and may
be changed without shareholder approval.

The New Vision Small Cap Fund pursues the objective of capital appreciation by
investing primarily in equity securities of small companies with promising
growth potential. These companies typically are developing innovative products
or services to seize emerging opportunities.

Under normal circumstances, the New Vision Small Cap Fund will invest at least
65% of its total assets in equity securities of companies publicly traded in
the United States (currently those with a total market capitalization of under
$1 billion at the time of the Fund's initial investment).

The New Vision Small Cap Fund considers issuers of all industries with
operations in all geographic markets, and does not seek interest income or
dividends. Equity securities may include common stocks, preferred stocks,
convertible securities and warrants. The Fund may hold cash or cash
equivalents for temporary defensive purposes or to enable it to take advantage
of buying opportunities. There is, of course, no assurance that the Fund will
be successful in meeting its objective.

Companies whose capitalization increases or decreases after initial purchase
by the Fund continue to be considered small-capitalized for purposes of the
65% policy. Accordingly, less than 65% of the Fund's total assets may be
invested in securities of issuers of companies publicly traded in the United
States (currently those with a total market capitalization of less than $1
billion).

The New Vision Small Cap Fund will normally be as fully invested as
practicable in common stocks (including ADRs), but also may invest in warrants
and rights to purchase common stocks and in debt securities and preferred
stocks convertible into common stocks (collectively, "equity securities").

INVESTMENT TECHNIQUES AND RISKS

Risks

A company's market capitalization is the total market value of its outstanding
equity securities. The value of the Fund's investments will vary from day to
day, and generally reflect market conditions, interest rates and other
company, political, or economic news. In the short-term, stock prices can
fluctuate dramatically in response to these factors. Over time, however,
stocks have shown greater growth potential than other types of securities.

Nondiversified

There may be risks associated with the Capital Accumulation Fund being
nondiversified. Specifically, since a relatively high percentage of the assets
of the Capital Accumulation Fund may be invested in the obligations of a
limited number of issuers, the value of the shares of the Capital Accumulation
Fund may be more susceptible to any single economic, political or regulatory
event than the shares of a diversified fund would be.

Small Cap Issuers

While any investment in securities carries a certain degree of risk, the
approach of the Fund is designed to maximize growth in relation to the risks
assumed. The securities of small cap issuers may be less actively traded than
the securities of larger issuers, may trade in a more limited volume, and may
change in value more abruptly than securities of larger companies.

Information concerning these securities may not be readily available so that
the companies may be less actively followed by stock analysts. Small-cap
issuers do not usually participate in market rallies to the same extent as
more widely-known securities, and they tend to have a relatively higher
percentage of insider ownership.

Investing in smaller, new issuers generally involves greater risk than
investing in larger, established issuers. Companies in which the Fund is
likely to invest may have limited product lines, markets or financial
resources and may lack management depth. The securities in such companies may
also have limited marketability and may be subject to more abrupt or erratic
market movements than securities of larger, more established companies or the
market averages in general. Accordingly an investment in the Fund may not be
appropriate for all investors.

Temporary defensive positions

Under normal market conditions the Fund strives to be fully invested in
securities. However, for temporary defensive purposes - which may include a
lack of adequate purchase candidates or an unfavorable market environment -
the Capital Accumulation Fund may invest up to 100% of its total assets, and
the New Vision Small Cap Fund may invest up to 35% of its total assets, in
cash or cash equivalents. Cash equivalents include instruments such as, but
not limited to, U.S. government and agency obligations, certificates of
deposit, bankers' acceptances, time deposits, commercial paper, short-term
corporate debt securities and repurchase agreements.

The Fund currently intends to invest no more than 5% of its net assets in
noninvestment-grade debt obligations. Although the Capital Accumulation Fund
invests primarily in equity securities, it may invest in debt securities and,
although the New Vision Small Cap Fund also invests primarily in equity
securities, it may invest up to 35% of its total assets in debt securities,
excluding money market instruments. These debt securities may consist of
investment-grade and noninvestment-grade obligations. Investment-grade
obligations are those which, at the date of investment, are rated within the
four highest grades established by Moody's Investors Services, Inc. (Aaa, Aa,
A, or Baa) or by Standard and Poor's Corporation (AAA, AA, A, or BBB), or, if
unrated, are deemed to be of comparable quality by the Advisor.
Noninvestment-grade securities are those rated below Baa or BBB, or unrated
obligations that the investment subadvisor has determined are not
investment-grade; such securities are speculative in nature, the Funds
currently intend to limit such investments to 5% of their respective net
assets. The Funds will not buy debt securities rated lower than C.

Interest-rate risk

All fixed income instruments are subject to interest-rate risk: that is, if
market interest rates rise, the current principal value of a bond will
decline. In general, the longer the maturity of the bond, the greater the
decline in value will be.

The Fund may use options and futures as defensive strategies.

The Capital Accumulation Fund may attempt to reduce the overall risk of its
investments by using options and futures contracts. An option is a legal
contract that gives the holder the right to buy or sell a specified amount of
the underlying interest at a fixed or determinable price (called the exercise
or strike price) upon exercise of the option. A futures contract is an
agreement to take delivery or to make delivery of a standardized quantity and
quality of a certain commodity during a particular month in the future at a
specified price. The Subadvisor will make decisions whether to invest in these
instruments based on market conditions, regulatory limits and tax
considerations. If this strategy is used, the Fund may be required to cover
assets used for this purpose in a segregated account for the protection of
shareholders.

In extraordinary circumstances, the New Vision Small Cap Fund may use options
and futures contracts to increase or decrease its exposure to changing
security prices, interest rates, or other factors that affect security values.
These techniques may involve derivative transactions such as buying and
selling options and futures contracts and leveraged notes, entering into swap
agreements, and purchasing indexed securities. The Fund can use these
practices only as protection against an adverse move of the holdings in the
Fund to adjust the risk and return characteristics of the Fund. The decision
to invest in these instruments will be based on market conditions, regulatory
limits and tax considerations. If market conditions are judged incorrectly, a
strategy does not correlate well with the Fund's investments, or if the
counterparty to the transaction does not perform as promised, these techniques
could result in a loss. These techniques may increase the volatility of the
Fund and may involve a small investment of cash relative to the magnitude of
the risk assumed. Any instruments determined to be illiquid are subject to the
Fund's limitation on illiquid securities. See below and the Statement of
Additional Information for more details about these strategies.

Risks of using defensive strategies

There can be no assurance that engaging in options, futures, or any other
defensive strategy will be successful. While defensive strategies are designed
to protect the Funds from potential declines, if the Subadvisor misgauges
market values, interest rates, or other economic factors, the Funds may be
worse off than had they not employed the defensive strategy. While the
Subadvisors attempt to determine price movements and thereby prevent declines
in the value of portfolio holdings, there is a risk of imperfect or no
correlation between price movements of portfolio investments and instruments
used as part of a defensive strategy so that a loss is incurred. While
defensive strategies can reduce the risk of loss, they can also reduce the
opportunity for gain since they offset favorable price movements. The use of
defensive strategies may result in a disadvantage to the Funds if a Fund is
not able to purchase or sell a portfolio holding at an optimal time due to the
need to cover its transaction in its segregated account, or due to the
inability of a Fund to liquidate its position because of its relative
illiquidity.

Repurchase agreements

The Funds may engage in repurchase agreements 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. The Funds 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
Funds' respective Board of Directors/Trustees. In addition, the Funds will
only engage in repurchase agreements reasonably designed to fully secure
during the term of the agreement, the seller's obligation to repurchase the
underlying security. The Funds will monitor the market value of the underlying
security during the term of the agreement. If the seller defaults on its
obligation to repurchase and the value of the underlying security declines,
the Funds may incur a loss and may incur expenses in selling the underlying
security. Repurchase agreements are always for periods of less than one year,
and are considered illiquid if not terminable within seven days.

Foreign Securities and ADRs

The New Vision Small Cap Fund may invest up to 15% of its total assets in
ADRs. The Capital Accumulation Fund may also invest in ADRs, subject to the
restrictions applicable to investments in foreign securities discussed below.
By investing in ADRs rather than directly in foreign issuers' stock, the Funds
may avoid some currency and some liquidity risks. The information available
for ADRs is subject to the more uniform and more exacting accounting, auditing
and financial reporting standards of the domestic market or exchange on which
they are traded. U.S. dollar-denominated ADRs, which are traded in the U.S. on
exchanges or over the counter, are receipts typically issued by a U.S. bank or
trust company which evidence ownership of underlying securities of a foreign
corporation.

The Capital Accumulation Fund may invest up to 25% of its assets in the
securities of foreign issuers, although it currently holds or intends to hold
no more than 5% of its assets in such securities. The Capital Accumulation
Fund may purchase foreign securities directly, on foreign markets, or those
represented by ADRs, or other receipts evidencing ownership of foreign
securities, such as International Depositary Receipts and Global Depositary
Receipts. Foreign securities may involve additional risks, including currency
fluctuations, risks relating to political or economic conditions, and the
potentially less stringent investor protection and disclosure standards of
foreign markets. These factors could make foreign investments, especially
those in developing countries, less liquid and more volatile. In addition, the
costs of foreign investing, including withholding taxes, brokerage commissions
and custodial costs are generally higher than for U.S. investments. See the
SAI for more information on investing in foreign securities.

The Funds may lend their portfolio securities.

Both Funds may lend portfolio securities to member firms of the New York Stock
Exchange and commercial banks with assets of one billion dollars or more,
although the New Vision Small Cap Fund does not intend to do so and the
Capital Accumulation Fund does not currently intend to lend more than 5% of
its portfolio securities. The advantage of such loans is that the Funds
continue to receive the equivalent of the interest earned or dividends paid by
the issuers on the loaned securities while at the same time earning interest
on the cash or equivalent collateral which may be invested in accordance with
the Funds' investment objective, policies and restrictions. As with any
extension of credit, there may be risks of delay in recovery and possibly loss
of rights in the loaned securities should the borrower of the loaned
securities fail financially.

Borrowing

Both Funds may borrow money from banks (and pledge its assets to secure such
borrowing) for temporary or emergency purposes, but not for leverage. Such
borrowing may not exceed one third of the value of each Fund's total assets.

High Social Impact Investments

The Funds have both adopted nonfundamental policies that permit investments
which, with respect to the Capital Accumulation Fund, may be up to three
percent, and with respect to the New Vision Small Cap Fund, may be up to one
percent, of that Fund's assets in securities that offer a rate of return below
the then-prevailing market rate and that present attractive opportunities for
furthering each Fund's social criteria ("High Social Impact Investments").
These securities are typically illiquid and unrated and are generally
considered noninvestment-grade debt securities, which involve a greater risk
of default or price decline than investment-grade securities. Through
diversification and credit analysis and limited maturity, investment risk can
be reduced, although there can be no assurance that losses will not occur. The
High Social Impact Investments committee of the Board of Directors/Trustees
identifies, evaluates and selects these investments, subject to ratification
by the respective Board.

Socially Responsible Investment Criteria

The Funds carefully review company policies and behavior regarding social
issues important to quality of life:

         environment
         employee relations
         product criteria
         weapons systems
         nuclear energy
         human rights

Once securities are determined to fall within the investment objective of a
Fund and are deemed financially viable investments, they are analyzed
according to the social criteria described below. These social screens are
applied to potential investment candidates by the Advisor in consultation with
the Subadvisors.

The following criteria may be changed by the respective Fund's Board of
Directors/Trustees without shareholder approval:

         (1) The Funds avoid investing in companies that, in the Advisor's
opinion, have significant or historical patterns of violating environmental
regulations, or otherwise have an egregious environmental record.
Additionally, the Funds will avoid investing in nuclear power plant operators
and owners, or manufacturers of key components in the nuclear power process.

         (2) The Funds will not invest in companies that are significantly
engaged in weapons production. This includes weapons systems contractors and
major nuclear weapons systems contractors.

         (3) The Funds will not invest in companies that, in the Advisor's
opinion, have significant or historical patterns of discrimination against
employees on the basis of race, gender, religion, age, disability or sexual
orientation, or that have major labor-management disputes.

         (4) The Funds will not invest in companies that are significantly
involved in the manufacture of tobacco or alcohol products. The Funds will not
invest in companies that make products or offer services that, under proper
use, in the Advisor's opinion, are considered harmful.

The Advisor will seek to review companies' overseas operations consistent with
the social criteria stated above.

While the Funds may invest in companies that exhibit positive social
characteristics, it makes no explicit claims to seek out companies with such
practices.

TOTAL RETURN

The Funds may advertise total return for each class of shares. Total return is
based on historical results and is not intended to indicate future performance.

Total return is calculated separately for each class. It includes not only the
effect of income dividends but also any change in net asset value, or
principal amount, during the stated period. The total return of a class shows
its overall change in value, including changes in share price and assuming all
of the class' dividends and capital gain distributions are reinvested. A
cumulative total return reflects the class' performance over a stated period
of time. An average annual total return ("return with maximum load") reflects
the hypothetical annual compounded return that would have produced the same
cumulative total return if the performance had been constant over the entire
period. Because average annual returns tend to smooth out variations in the
returns, you should recognize that they are not the same as actual
year-by-year results. Both types of return usually will include the effect of
paying any sales charge. Of course, total returns will be higher if sales
charges are not taken into account. Quotations of "return without maximum
sales load" do not reflect deduction of the sales charge. You should consider
these figures only if you qualify for a reduced sales charge, or for purposes
of comparison with comparable figures which also do not reflect sales charges,
such as mutual fund averages compiled by Lipper Analytical Services, Inc.
("Lipper"). Further information about the Funds' performance is contained in
its Annual Report to Shareholders, which may be obtained without charge.

MANAGEMENT OF THE FUND

The Funds' Board of Directors/Trustees supervise the Funds' activities and
review their contracts with companies that provide them with services.

The Capital Accumulation Fund is a series of Calvert World Values Fund, Inc.
an open-end management investment company organized as a Maryland corporation
on February 14, 1992. The other series is the International Equity Fund, a
socially-screened portfolio of equity securities from around the world.

The New Vision Small Cap Fund is a series of The Calvert Fund (the "Trust"),
an open-end management investment company organized as a Massachusetts
business trust on March 15, 1982. The other series of the Trust is the Calvert
Income Fund.

Neither Fund is required to hold annual shareholder meetings, but special
meetings may be called for certain purposes such as electing
Directors/Trustees, changing fundamental policies, or approving a management
contract. As a shareholder, you receive one vote for each share of a Fund you
own. Matters affecting classes differently, such as Distribution Plans, will
be voted on separately by class.

Calvert Asset Management Company, Inc. serves as Advisor to the Funds.

Calvert Asset Management Company, Inc. (the "Advisor") is both Funds'
investment advisor. The Advisor provides the Funds with investment supervision
and management; administrative services and office space; furnishes executive
and other personnel to the Funds; and pays the salaries and fees of all
Directors/Trustees who are affiliated persons of the Advisor. The Advisor may
also assume and pay certain advertising and promotional expenses of the Funds
and reserves the right to compensate broker/dealers in return for their
promotional or administrative services. The Funds pay all other operating
expenses as noted in the SAI.

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

Calvert Group, Ltd., parent of the Fund's Advisor, shareholder servicing 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, 1997, Calvert Group managed and administered assets in
excess of $5.0 billion and more than 200,000 shareholder and depositor
accounts.

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

The respective Investment Advisory Agreements between the Funds and the
Advisor both provide that the Advisor is entitled to a base annual fee,
payable monthly, of 0.80% of the Capital Accumulation Fund's, and 0.90% of the
New Vision Small Cap Fund's, average daily net assets. For its services during
the fiscal year ended September 30, 1997, pursuant to the Investment Advisory
Agreements, the Advisor received an investment advisory fee of 0.80% of the
Capital Accumulation Fund's average daily net assets, and 0.90% of New Vision
Small Cap Fund's average daily net assets.

With respect to the Capital Accumulation Fund, the Advisor may earn (or have
its fee reduced by) a performance adjustment based on the extent to which
performance of the Fund exceeds or trails the Standard & Poor's 400 Mid-Cap
Index:

     Performance versus the         Performance Fee
     S&P 400 Mid-Cap Index          Adjustment

     10% to less than 25%           0.01%
     25% to less than 40%           0.03%
     40% or more                    0.05%

For its services for fiscal year 1997, the Advisor received, pursuant to the
Investment Advisory Agreement, an advisory fee of 0.80% of the Fund's average
daily net assets, which included a performance adjustment of 0.0054%. The
Advisor may in its discretion defer its fees or assume the Fund's operating
expenses.

Brown Capital Management, Inc., ("Brown Capital") is the investment subadvisor
for the Capital Accumulation Fund.

Brown Capital of 809 Cathedral Street, Baltimore, Maryland has served as
subadvisor to the Fund since November 1, 1994. Brown Capital believes that
capital can be enhanced in times of opportunity and preserved in times of
adversity without timing the market. The firm uses a bottom-up approach that
incorporates growth-adjusted price earnings. Stocks purchased are generally
undervalued and have momentum, have earnings per share growth rates greater
than the market, are more profitable than the market, and have relatively low
price-earnings ratios. Its performance index is a blended 60% Russell 1000
Growth and 40% Russell 2000.

Eddie C. Brown is founder and President of Brown Capital. He has over 22 years
of investment experience, having served as a Vice President and Portfolio
Manager for 10 years at T. Rowe Price Associates immediately prior to starting
his own firm. Mr. Brown holds an MS in Electrical Engineering from New York
University, and an MS in Business Administration from the Indiana University
School of Business. Additionally, he is a professionally-designated Chartered
Financial Analyst (CFA) and Chartered Investment Counselor.

The Investment Subadvisory Agreement between the Advisor provides that Brown
Capital is entitled to a base subadvisory fee of 0.25% of the Fund's average
daily net assets, paid by the Advisor out of the fee the Advisor receives from
the Fund. Brown Capital may earn (or have its base fee reduced by) a
performance adjustment based on the extent to which performance of the Fund
exceeds or trails the index agreed on with the Advisor:

     Performance versus             Performance Fee
     the Index                      Adjustment

     10% to less than 25%           0.02%
     25% to less than 40%           0.05%
     40% or more                    0.10%

Payment by the Fund of a performance adjustment will be conditioned on: (1)
the performance of the Fund as a whole having exceeded the S&P 400 Mid-Cap
Index; and (2) payment of the performance adjustment not causing the Fund's
performance to fall below the S&P 400 Mid-Cap Index. The performance
adjustment will be paid by the Fund to the Advisor, which will then pass it on
to the Subadvisor.

Awad & Associates ("AWAD") is the investment subadvisor to the New Vision
Small Cap Fund.

AWAD's principal business office is located at 477 Madison Avenue, New York,
New York 10022. As of June 30, 1997, AWAD had $724 million in assets under
management. AWAD adheres to a bottom-up, earnings-driven discipline with
emphasis on internal fundamental research, specializing in small
capitalization stocks, focusing on growth at a reasonable [value] price
approach to stock selection. AWAD's main objectives in asset management are to
protect the investor's capital, generate capital appreciation substantially in
excess of inflation and reduced-risk returns and provide returns in excess of
applicable stock and bond indices. All portfolio investments are regularly
scrutinized to provide a substantial risk/return benefit and to ensure that
portfolios are properly positioned relative to the Fund's investment
objectives.

Since October 1, 1997, the New Vision Small Cap Fund has been managed by a
team of investment professionals from AWAD. The senior investment officer is
James D. Awad. Mr. Awad has been in the investment business since 1965,
focusing on research and portfolio management. Prior to forming AWAD, he was
President of BMI Capital, a successful money management firm he founded. In
addition, he has managed assets at Neuberger & Berman, Channing Management and
First Investment Corp. Mr. Awad has earned an MBA from Harvard Business School
and a BS Cum Laude from Washington & Lee University.

Dennison T. Veru is President of AWAD. Mr. Veru joined AWAD in 1992 coming
from Smith Barney Harris Upham where he was Senior Vice President of the
firm's Whiffletree Capital Management division specializing in small and medium
capitalization stocks. From 1988 through 1990, he was a Vice President of
Broad Street Investment Management. Prior to that, he was an Assistant Vice
President at Drexel Burnham Lambert. Mr. Veru is a graduate of Franklin and
Marshall College.

The Investment Subadvisory Agreement between the Advisor and AWAD provides
that AWAD is entitled to a base subadvisory fee of 0.40% of the Fund's average
daily net assets managed by AWAD. AWAD's fee is paid by the Advisor out of the
fee the Advisor receives from the Fund.

The Funds have obtained an exemptive order from the Securities and Exchange
Commission to permit them, pursuant to approval by the Board of
Directors/Trustees, to enter into and materially amend contracts with a
Subadvisor without shareholder approval. See "Investment Advisor and
Subadvisor" in the SAI for further details.

the Fund.

provides certain administrative services to the Fund, including the
preparation of regulatory filings and shareholder reports, the daily
determination of its net asset value per share and dividends, and the
maintenance of its portfolio and general accounting records. For providing
such services, CASC receives an annual fee, payable monthly, from both Funds
of 0.10% of the respective Fund's average daily net assets.

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

Calvert Distributors, Inc. ("CDI") is both Funds' principal underwriter and
distributor. Under the terms of its underwriting agreement with the Funds, CDI

Each Fund offers its shareholders three classes of shares:

Class A Shares - Front End Load Option

Class A shares are sold with a front-end sales charge at the time of purchase.
Class A shares are not subject to a sales charge when they are redeemed.

Class B Shares - Back-End Load Option

Class B shares are sold without a sales charge at the time of purchase, but
are subject to a deferred sales charge if they are redeemed within six
calendar years after purchase. Class B shares will automatically convert to
Class A shares at the end of eight calendar years after purchase.

Class C shares - Level Load Option

Class C shares are sold without a front-end sales charge at the time of
purchase. They are subject to a deferred sales charge if they are redeemed
within one year after purchase.


Class B and C shares have higher expenses than Class A shares.

Each Fund bears some of the costs of selling its shares under Distribution
Plans adopted pursuant to Rule 12b-1 under the 1940 Act. Payments under the
Class A Distribution Plan are limited to up to 0.35% with respect to the
Capital Accumulation Fund, and up to 0.25% with respect to the New Vision
Small Cap Fund, annually of the average daily net asset value of Class A
shares, while payments under Class B and C Distribution Plan are 1.00% of the
average daily net assets attributable to their respective classes of each Fund.

Considerations for deciding which class of shares to buy.

Income distributions for Class A shares will probably be higher than those for
Class B and Class C shares, as a result of the distribution expenses described
above. (See also "Total Return") You should consider Class A shares if you
qualify for a reduced sales charge under Class A. Class A shares may also be
more appropriate for larger accounts or if you plan to hold the shares for
several years. Class C shares are not available for investments of $1 million
or more. The Funds will not normally accept any purchase of Class B shares in
the amount of $250,000 or more.

Class A Shares

Class A shares are offered at net asset value ("NAV") plus a front-end sales
charge calculated as follows:

                                                              Allowed

* CDI may pay the dealer a finder's fee of up to 0.50% of the amount of
purchase on purchases of over $1 million. CDI reserves the right to recoup any
portion of the amount paid to the dealer if the investor redeems some or all
of the shares from the Fund within twelve months of the time of purchase.

Sales charges on Class A shares may be reduced or eliminated in certain cases.
See Exhibit A to this prospectus.

The sales charge is paid to CDI, which in turn normally reallows a portion to
your broker/dealer. Upon written notice to dealers with whom it has dealer
agreements, CDI may reallow up to the full applicable sales charge. Dealers to
whom 90% or more of the entire sales charge is reallowed may be deemed to be
underwriters under the Securities Act of 1933.

In addition to any sales charge reallowance or finder's fee, your
broker/dealer, or other financial service firm through which your account is
held, currently will be paid periodic service fees at an annual rate of up to
0.25% of the average daily net asset value of Class A shares held in accounts
maintained by that firm.

Class A Distribution Plan

Each Fund has adopted a Distribution Plan with respect to its Class A shares
(the "Class A Distribution Plan"), which provides for payments at a maximum
rate of 0.35% with respect to the Capital Accumulation Fund, and 0.25% with
respect to the New Vision Small Cap Fund, of the average daily net asset value
of Class A shares, to pay expenses associated with the distribution and
servicing of Class A shares. Amounts paid by the Fund to CDI under the Class A
Distribution Plan are used to pay to broker/dealers and others, including CDI
salespersons who service accounts, service fees at an annual rate of up to
0.25% of the average daily net asset value of Class A shares, and to pay CDI
for its marketing and distribution expenses, including, but not limited to,
preparation of advertising and sales literature and the printing and mailing
of prospectuses to prospective investors. During the fiscal year ended
September 30, 1997, Class A Distribution Plan expenses for the Capital
Accumulation Fund were 0.35% and for the New Vision Small Cap Fund were 0.25%.

Class B Shares

Class B shares are offered at net asset value, without a front-end sales
charge. With certain exceptions, the Portfolio may impose a deferred sales
charge at the time of redemption as follows:

                                          Contingent Deferred Sales
                                          Charge As A Percentage Of
Redemption During                         Net Asset Value At Redemption

1st Year Since Purchase                   5%
2nd Year Since Purchase                   4%
3rd Year Since Purchase                   4%
4th Year Since Purchase                   3%
5th Year Since Purchase                   2%
6th Year Since Purchase                   1%
7th Year Since Purchase and Thereafter    None

No deferred sales charge is imposed on amounts redeemed after six years from
purchase. If imposed, the deferred sales charge is deducted from the
redemption proceeds otherwise payable to you. The deferred sales charge is
retained by CDI. See "Calculation of Contingent Deferred Sales Charges and
Waiver of Sales Charges" below.

Class B shares that have been outstanding for eight calendar years will
automatically convert to Class A shares, which are subject to a lower
Distribution Plan charge, without imposition of a front-end sales charge or
exchange fee. The Class B shares so converted will no longer be subject to the
higher expenses borne by Class B shares. Because the net asset value per share
of the Class A shares may be higher or lower than that of the Class B shares
at the time of conversion, although the dollar value will be the same, a
shareholder may receive more or less Class A shares than the number of Class B
shares converted. Under current law, it is the Advisor's opinion that such a
conversion will not constitute a taxable event under federal income tax law.
In the event that this ceases to be the case, the Board of Trustees will
consider what action, if any, is appropriate and in the best interests of the
Class B shareholders.

Class B Distribution Plan

The Portfolio has adopted a Distribution Plan with respect to its Class B
shares (the "Class B Distribution Plan"), which provides for payments at an
annual rate of up to 1.00% of the average daily net asset value of Class B
shares, to pay expenses of the distribution of Class B shares. Amounts paid by
the Portfolio under the Class B Distribution Plan are currently used by CDI to
pay others (1) a commission at the time of purchase of 4% of the value of each
share sold; and/or (2) service fees at an annual rate of 0.25% of the average
daily net asset value of shares sold by such others, beginning in the 13th
month after purchase.

Class C Shares

Class C shares are not available through all dealers. Class C shares are
offered at net asset value, without a front-end sales charge. With certain
exceptions, the Portfolio will impose a deferred sales charge of 1.00% on
shares redeemed during the first year after purchase. If imposed, the deferred
sales charge is deducted from the redemption proceeds otherwise payable to
you. The deferred sales charge is retained by CDI. See "Calculation of
Contingent Deferred Sales Charges and Waiver of Sales Charges" below

Class C Distribution Plan

Each Fund has adopted a Distribution Plan with respect to its Class C shares
(the "Class C Distribution Plan"), which provides for payments at an annual
rate of up to 1.00% of the average daily net asset value of Class C shares, to
pay expenses of the distribution and servicing of Class C shares. Amounts paid
by the Fund under the Class C Distribution Plan are currently used by CDI to
pay broker/dealers and other selling firms (1) a commission at the time of
purchase of 1.00% of the value of each share sold, and (2) beginning in the
13th month after purchase, quarterly compensation at an annual rate of up to
0.75%, plus a service fee of up to 0.25%, of the average daily net asset value
of each share sold by such others. During the fiscal year ended September 30,
1997, Class C Distribution Plan expenses for the Capital Accumulation Fund
were 1.00% of the average daily net assets. For the period ended September 30,
1997, distribution expenses for the New Vision Small Cap Fund were 1.00% of
the average daily net assets.

Calculation of Contingent Deferred Sales Charge and Waiver of Sales Charges

Class B and Class C shares that are redeemed will not be subject to a
contingent deferred charge to the extent that the value of such shares
represents (1) reinvestment of dividends or capital gains distributions, (2)
shares held more than six years (more than one year for Class C) or (3)
capital appreciation of shares redeemed. Any contingent deferred sales charge
is imposed on the net asset value of the shares at the time of redemption or
purchase, whichever is lower. Upon request for redemption, shares not subject
to the contingent deferred sales charge will be redeemed first. Thereafter,
shares held the longest will be the first to be redeemed.

The contingent deferred sales charge on Class B Shares will be waived in the
following circumstances: (1) redemption upon the death or disability of the
shareholder, plan participant, or beneficiary ("disability" shall mean a total
disability as evidenced by a determination by the federal Social Security
Administration); (2) minimum required distributions from retirement plan
accounts for shareholders 70 1/2 and older (with the maximum amount subject to
this waiver being based only upon the shareholder's Calvert retirement
accounts); (3) return of an excess contribution or deferral amounts, pursuant
to sections 408(d)(4) or (5), 401(k)(8), or 402)(g)(2), or 401(m)(6) of the
Internal Revenue Code; (4) involuntary redemptions of accounts under
procedures set forth by the Fund's Board of Trustees; (5) a single annual
withdrawal under a systematic withdrawal plan of up to 10% per year of the
shareholder's account balance (minimum account balance $50,000 to establish).

Arrangements with Broker/dealers and Others

CDI may also pay additional concessions, including non-cash promotional
incentives, such as merchandise or trips, to dealers employing registered
representatives who have sold or are expected to 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 and in compliance with
the rules of the NASD.

Broker/dealers or others may receive different levels of compensation
depending on which class of shares they sell. Payments pursuant to a
Distribution Plan are included in the operating expenses of the class.

WHEN YOUR ACCOUNT WILL BE CREDITED

Your purchase will be processed at the next NAV calculated after your order is
received and accepted. All of your purchases must be made in US dollars and
checks must be drawn on US banks. No cash will be accepted. The Funds reserve
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 bank, your
purchase will be canceled and you will be charged a $10 fee plus costs
incurred by the Funds.

When you purchase by check or with Calvert Money Controller, the purchase will
be on hold for up to 10 business days from the date of receipt. During the
hold period, any redemptions will be held until the transfer agent is
reasonably satisfied that the purchase payment has been collected. To avoid
this hold period, you can wire federal funds from your bank, which may charge
you a fee. As a convenience, check purchases can be received at Calvert's
offices for overnight mail delivery to the Transfer Agent and will be credited
the next business day, or upon receipt. Any check purchase received without an
investment slip may cause delayed crediting.

Certain financial institutions or broker/dealers which have entered into a
sales agreement with CDI may enter confirmed purchase orders on behalf of
customers by phone, with payment to follow within a certain number of days of
the order as specified by the program. If payment is not received in the time
specified, the financial institution or broker/dealer could be held liable for
resulting fees or losses.

TAX-SAVING RETIREMENT PLANS

Calvert Group also offers its shareholders several tax-deferred retirement
plans that allow you to invest for retirement and shelter your investment
income from current taxes. Please contact us if you wish to obtain more

employees, and certain tax-exempt organizations.

TELEPHONE TRANSACTIONS
You may purchase, redeem, or exchange shares, wire funds and use Calvert Money
Controller by telephone if you have pre-authorized service instructions. You
receive this service automatically when you open your account unless you elect
otherwise. For our mutual protection, the Fund, the shareholder servicing
agent and their affiliates use precautions such as verifying shareholder

EXCHANGES
Calvert Group offers a wide variety of investment options that includes common
stock funds, tax-exempt and corporate bond funds, and money market funds (call
your broker or Calvert representative for more information). We make it easy
for you to purchase shares in other funds should your investment goals change.
The exchange privilege offers flexibility, by allowing you to exchange shares
on which you have already paid a sales charge from one mutual fund to another
at no additional charge.

Complete and sign an account application, 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.

Before you make an exchange, please note the following:
         Each exchange represents the sale of shares of one portfolio and the
purchase of shares of another. Therefore, you could realize a taxable gain or
loss.

         No CDSC is imposed on exchanges of shares subject to a CDSC at the
time of the exchange. The applicable CDSC is imposed at the time the shares
acquired by the exchange are redeemed.

         Shareholders (and those managing multiple accounts) who make two
purchases and two exchange redemptions of shares of the same Portfolio during
a six months period will be given written notice and may be prohibited from
placing additional investments. This policy does not prohibit a shareholder
from redeeming shares of any Portfolio, and does not apply to trades solely
among money market funds.

         The Fund reserves the right to terminate or modify the exchange
privilege with 60 days written notice. For purposes of the exchange privilege,
the Funds are related to Summit Cash Reserves Fund by investment and investor
services.

          COMBINED GENERAL MAILINGS
Join is in our efforts to conserve paper and save on postage

If you have multiple accounts with Calvert, you may receive combined mailings
of shareholder information, such as account statements, confirmations of
transactions, prospectuses and semi-annual and annual reports.

SPECIAL SERVICES AND CHARGES

The Funds pay 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 or a stop payment on a draft. You may be required to pay a fee
for these special services; for example, the fee for stop payments is $25.

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

MINIMUM ACCOUNT BALANCE IS $1,000 per Fund, per Class

Please maintain a balance in each of your Fund accounts of at least $1,000. If
the balance in your account falls below the $1,000 minimum during a month, the
account may be closed and the proceeds mailed to the address of record. You
will receive a notice that your account is below the minimum, and will be
closed if the balance is not brought up to the required minimum amount within
30 days.

SYSTEMATIC CHECK REDEMPTIONS

If you maintain an account with $10,000 or more, you may have up to two (2)
redemption checks for $100 or more sent to you on the 15th of each month,
simply by sending a letter with all the information, including your account
numbers, and the dollar amount. If you would like a regular check mailed to
another person or place, your letter must be signature guaranteed. Unless they
otherwise qualify for a waiver, Class B or Class C shares redeemed by
Systematic Check Redemption will be subject to the Contingent Deferred Sales
Charge.

DIVIDENDS, CAPITAL GAINS AND TAXES

Each year, both Funds distribute substantially all of their respective net
investment income to their shareholders.

Dividends from a Fund's net investment income are declared and paid annually.
Net investment income consists of interest income, net short-term capital
gains, if any, and dividends declared and paid on investments, less expenses.
Distributions of net short-term capital gains (treated as dividends for tax
purposes) and net long-term capital gains, if any, are normally paid once a
year; however, the Funds do not anticipate making any such distributions
unless available capital loss carryovers have been used or have expired.
Dividend and distribution payments will vary between classes; dividend
payments are anticipated to be generally higher for Class A shares.

Dividend payment options (available monthly or quarterly)

Dividends and any distributions are automatically reinvested in the same
Portfolio at NAV (no sales charge), 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 any Calvert Group Fund or Portfolio may be
automatically invested in an identically registered account in any other
Calvert Group Fund at NAV. If reinvested in the same Fund account, new shares
will be purchased at NAV on the reinvestment date, which is generally 1 to 3
days prior to the payment date. You must notify the Funds in writing to change
your payment options. If you elect to have dividends and/or distributions paid
in cash, and the US Postal Service cannot deliver the check, or if it remains
uncashed for an extended period, it, as well as future dividends and
distributions, will be reinvested in additional shares. No dividends will
accrue on amounts represented by uncashed distribution or redemption checks.

Buying a Dividend

At the time of purchase, the share price of your Fund may reflect
undistributed income, capital gains or unrealized appreciation of securities.
Any income or capital gains from these amounts which are later distributed to
you are fully taxable. On the record date for a distribution, share value is
reduced by the amount of the distribution. If you buy shares just before the
record date ("buying a dividend") you will pay the full price for the shares
and then receive a portion of the price back as a taxable distribution.

Federal Taxes

In January, your Fund will mail you Form 1099-DIV indicating the federal tax
status of dividends and any capital gain distributions paid to you during the
past year. Generally, dividends and distributions are taxable in the year they
are paid. However, any dividends and distributions paid in January but
declared during the prior three months are taxable in the year declared.
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
shares.

You may realize a capital gain or loss when you sell or exchange shares. This
capital gain or loss will be short- or long-term, depending on how long you
have owned the shares which were sold. In January, the Portfolios will mail
you Form 1099-B indicating the total amount of all sales, including exchanges.
You should keep your annual year-end account statements to determine the cost
(basis) of the shares to report on your tax returns.

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 US
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 us to withhold 31% of your dividends, and possibly 31% of certain
redemptions. 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 (closed) at the current NAV on the date of redemption. Calvert
Group reserves the right to reject any new account or any purchase order for
failure to supply a certified TIN.

HOW TO SELL SHARES

You may redeem all or a portion of your shares on any business day. Your
shares will be redeemed at the next NAV calculated after your redemption
request is received (less any applicable CDSC). The proceeds will normally be
sent to you on the next business day, but if making immediate payment could
adversely affect the Funds, 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. Remember, investments made by check
or Calvert Money Controller may be subject to a hold before shares can be
redeemed. 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.

Net Asset Value - "NAV"
NAV refers to the worth of one share. NAV is computed by adding the value of
all portfolio holdings, plus other assets, deducting liabilities and then
dividing the result by the number of shares outstanding. For Portfolios with
more than one class of shares, the NAVs of each class will vary daily
depending on the number of shares outstanding for each class.

Portfolio securities and other assets are valued based on market quotations,
except that securities maturing within 60 days are valued at amortized cost.
Money Market securities are valued according to the "amortized cost" method,
which is intended to stabilize the NAV at $1 per share. If quotations are not
available, securities are valued by a method that the particular Fund's Board
of Trustees/Directors believes accurately reflects fair value.

The NAV is calculated at the close of each business day, which coincides with
the closing of the regular session of the New York Stock Exchange (normally 4
p.m. ET). Both Funds are open for business each day the New York Stock
Exchange is open. All purchases will be confirmed and credited to your account
in full and fractional shares (rounded to the nearest 1/1000 of a share).

Follow these suggestions to ensure timely processing of your redemption request

Exhibit A

REDUCED SALES CHARGES (Class A Only)

You may qualify for a reduced sales charge through several purchase plans
available. You must notify the Funds at the time of purchase to take advantage
of the reduced sales charge.

Right of Accumulation
The sales charge breakpoints are calculated by taking into account not only
the dollar amount of a new purchase of shares, but also the higher of cost or
current value of shares previously purchased in Calvert Group Funds that
impose sales charges. This automatically applies to your account for each new
purchase.

Letter of Intent
If you plan to purchase $50,000 or more of Fund shares over the next 13
months, your sales charge may be reduced through a "Letter of Intent." You pay
the lower sales charge applicable to the total amount you plan to invest over
the 13-month period, excluding any money market fund purchases. Part of your
shares will be held in escrow, so that if you do not invest the amount
indicated, you will have to pay the sales charge applicable to the smaller
investment actually made. For more information, see the SAI.

Group Purchases
If you are a member of a qualified group, you may purchase shares at the
reduced sales charge applicable to the group taken as a whole. The sales
charge is calculated by taking into account not only the dollar amount of the
shares you purchase, but also the higher of cost or current value of shares
previously purchased and currently held by other members of your group.

A "qualified group" is one which: has been in existence for more than six
months, has a purpose other than acquiring shares at a discount, and satisfies
uniform criteria which enable CDI and brokers offering shares to realize
economies of scale in distributing such shares.

A qualified group must have more than 10 members, must be available to arrange
for group meetings between representatives of CDI or brokers distributing
shares, must agree to include sales and other materials related to the Funds
in its publications and mailings to members at reduced or no cost to CDI or
brokers.

Pension plans may not qualify participants for group purchases; however, such
plans may qualify for reduced sales charges under a separate provision (see
below). Members of a group are not eligible for a Letter of Intent.

Retirement Plans Under Section 457, Section 403(b)(7), or Section 401(k)
There is no sales charge on shares purchased for the benefit of a retirement
plan under section 457 of the Internal Revenue Code of 1986, as amended
("Code"), or for a plan qualifying under section 403(b) or 401(k) of the Code
if, at the time of purchase, (i) Calvert Group has been notified in writing
that the 403(b) or 401(k) plan has at least 200 eligible employees and is not
sponsored by a K-12 school district, or (ii) the cost or current value of
shares a 401(k) plan has in Calvert Group of Funds (except money market funds)
is at least $1 million.

Neither the Funds, nor CDI, nor any affiliate thereof will reimburse a plan or
participant for any sales charges paid prior to receipt of such written
communication and confirmation by Calvert Group. Plan administrators should
send requests for the waiver of sales charges based on the above conditions
to: Calvert Group Retirement Plans, 4550 Montgomery Avenue, Suite 1000N,
Bethesda, Maryland 20814.

Other Circumstances
There is no sales charge on shares of any fund or portfolio of the Calvert
Group of Funds sold to (i) current or retired Directors, Trustees, or Officers
of the Calvert Group of Funds, employees of Calvert Group, Ltd. and its
affiliates, or their family members; (ii) CSIF Advisory Council Members,
directors, officers, and employees of any subadvisor for the Calvert Group of
Funds, employees of broker/dealers distributing the Fund's shares and
immediate family members of the Council, subadvisor, or broker/dealer; (iii)
Purchases made through a Registered Investment Advisor, (iv) Trust departments
of banks or savings institutions for trust clients of such bank or
institution, (v) Purchases through a broker maintaining an omnibus account
with the fund or portfolio, provided the purchases are made by (a) investment
advisors or financial planners placing trades for their own accounts (or the
accounts of their clients) and who charge a management, consulting, or other
fee for their services; or (b) clients of such investment advisors or
financial planners who place trades for their own accounts if such accounts
are linked to the master account of such investment advisor or financial
planner on the books and records of the broker or agent; or (c) retirement and
deferred compensation plans and trusts, including, but not limited to, those
defined in section 401(a) or section 403(b) of the I.R.C., and "rabbi trusts."

Dividends and Capital Gain Distributions from other Calvert Group Funds
You may prearrange to have your dividends and capital gain distributions from
another Calvert Group Fund automatically invested in another account with no
additional sales charge.

Purchases made at NAV
Except for money market funds, if you make a purchase at NAV, you may exchange
that amount to another Calvert Group Fund at no additional sales charge.

Reinstatement Privilege
If you redeem shares and then within 30 days decide to reinvest in the same
Fund, you may do so at the net asset value next computed after the
reinvestment order is received, without a sales charge. You may use the
reinstatement privilege only once. The Funds reserve the right to modify or
eliminate this privilege.

                              INVESTMENT OBJECTIVE

         Calvert New Vision Small Cap Fund (the "Fund") is a diversified
series of The Calvert Fund, an open-end management investment company. The
investment objective of the Fund is to achieve long-term capital appreciation
by investing primarily in the equity securities of small companies (currently
those with a total capitalization for initial purchases of less than $1
billion at the time of the Fund's initial investment) publicly traded in the
United States. The following discussion supplements the discussion in the
Prospectus. Unless otherwise specified, the investment objective, programs and
restrictions of the Fund are not fundamental policies. The operating policies
of the Fund are subject to change by its Board of Trustees without shareholder
approval.
         In seeking capital appreciation, the Fund invests primarily in equity
securities of small capitalized growth companies that have historically
exhibited exceptional growth characteristics and that, in the Adviser's
opinion, have strong earnings potential relative to the U.S. market as a
whole. The Fund will take reasonable risks in seeking to achieve its
investment objective. There is, of course, no assurance that the Fund will be
successful in meeting its objective since there is risk involved in the
ownership of all equity securities. The Fund will invest in enterprises that
make a significant positive contribution to our society through their products
and services and through the way they do business.
         The  Fund's  investment  philosophy  emphasizes  sustained  growth  and
concentrates  on the  securities  of issuers  not  generally  recognized  by the
investment  community  that  have  a  consistent  earnings-per-share  growth,  a
unique product or service,  conservative  accounting and financial policies, and
management  capable of long-term  growth.  While the Fund's  policies  may, from
time to time,  result in income  return,  any such return will be  incidental to
the objective of long-term capital appreciation.
         Under  normal  market   conditions,   the  Fund  strives  to  be  fully
invested.  In a  declining  market,  the Fund may  raise  cash or  employ  other
defensive  strategies  in an  attempt  to  protect  against  the  decline of its
investments.

SPECIAL RISKS OF THE FUND'S DEFENSIVE STRATEGIES
         The Fund may purchase put and call  options,  and write (sell)  covered
put and call options on equity and debt  securities  and stock or debt  indices.
The Fund may  purchase  or write both  exchange-traded  and OTC  options.  These
defensive strategies may also be used with respect to futures.
         An option is a legal  contract  that  gives the holder the right to buy
or  sell  a  specified  amount  of  the  underlying   interest  at  a  fixed  or
determinable  price  (called the exercise or strike  price) upon exercise of the
option.  A  futures  contract  is an  agreement  to  take  delivery  or to  make
delivery of a standardized  quantity and quality of a certain  commodity  during
a particular  month in the future at a specified  price.  Successful  use of the
Fund's  investment  strategies  with  respect to futures and options  depends on
the  ability  to predict  movements  of the  overall  securities,  currency  and
interest rate markets,  which is a different  skill than that required to select
equity and debt  investments.  There can be no assurance that a chosen  strategy
will succeed.
         There may not be an expected  correlation  between price movements of a
hedging  instrument and price movements of the investment being hedged,  so that
the Fund may lose money notwithstanding employment of the hedging strategy.
         While the  Fund's  investment  strategies  can  reduce  risk of loss by
offsetting the negative  effect of unfavorable  price  movements,  they can also
reduce  the  opportunity  for  gain  by  offsetting  the  positive  effect  of a
favorable  price  movement.  If the variance is great  enough,  a decline in the
price of an instrument may result in a loss to the Fund.
         The Fund may be required to cover its assets in a  segregated  account.
If an investment  cannot be liquidated  at the time the  Subadvisor  believes it
is best for the Fund,  the Fund  might be  required  to keep  assets on  reserve
that it otherwise  would not have had to maintain.  Similarly,  it might have to
sell a security at an inopportune time in order to maintain the reserves.


FUTURES AND OPTIONS
         The Fund is authorized to invest in certain types of futures, options
on equities and equity indexes, warrants and stock rights for hedging purposes
only, that is, protecting against the risk of market movements that may
adversely affect the value of the Fund's securities or the price of securities
that the Fund is considering purchasing. Although a hedging transaction may
partially protect the Fund from a decline in the value of a particular
security or its portfolio generally, the cost of the transaction will reduce
the potential return on the security or the portfolio. The Fund may only write
call options on securities that it owns (i.e., that are "covered"). No more
than 50% of the Fund's total assets shall be subject to outstanding options
contracts. The Fund presently intends to cease writing options in the event
that 25% of total assets are subject to outstanding options contracts. As an
operating policy, the Fund may purchase a call or put option on securities
(including combinations of options such as straddles or spreads) only if the
value of that option premium, when aggregated with the premiums of all other
options on securities held by the Fund, does not exceed 5% of the Fund's
assets. Following is a summary of the futures, options, warrants and stock
rights in which the Fund may invest:
         In exchange for a premium, a call option on a security or security
index gives the holder (buyer) of the option the right (but not the
obligation) to purchase the underlying security or security index at a
specified price (the exercise price) at any time until a certain date (the
expiration date). The writer (seller) of a call option has the corresponding
obligation to deliver the underlying security in the event the option is
exercised by the holder of the option. A call option on a securities index is
similar to a call option on an individual security, except that the value of
the option depends on the weighted value of the group of securities comprising
the index and all settlements are to be made in cash. A call option may be
terminated by the writer (seller) by entering into a closing purchase
transaction in which the writer purchases an option of the same series as the
option previously written.
         The Fund may purchase put options on a security or security index. A
put option gives the holder (buyer) of the option the right (but not the
obligation) to sell a security at the exercise price at any time until the
expiration date. Upon exercise by the purchaser, the writer of a put option
has the obligation to purchase the underlying security at the exercise price.
A put option on a securities index is similar to a put option on an individual
security, except that the value of the option depends on the weighted value of
the group of securities comprising the index and all settlements are made in
cash. Purchasing a call or put option involves the risk that the Fund may lose
the premium it paid plus transactions costs.
         With respect to securities and securities indexes, the Fund may write
(sell) call and put options on an exchange or over-the-counter. Call options
on portfolio securities will be covered since the Fund will own the underlying
securities. Call options on securities indices will be written only to hedge
in an economically appropriate way portfolio securities which are not
otherwise hedged with options or financial futures contracts and will be
covered by maintaining sufficient collateral to cover the option.
         The Fund may write (sell) call and put options in order to obtain a
return on its investments from the premiums received and will retain the
premiums whether or not the options are exercised. Any decline in the market
value of portfolio securities will be offset to the extent of the premiums
received (net of transaction costs). If an option is exercised, the premium
received on the option will effectively increase the exercise price or reduce
the difference between the exercise price and market value. During the option
period, the writer of a call option gives up the opportunity for appreciation
in the market value of the underlying security or currency above the exercise
price. The writer retains the risk of loss should the price of the underlying
security decline.
         The Fund may also write a call or put option which it has previously
purchased prior to the purchase (in the case of a call) or the sale (in the
case of a put) of the underlying security. Any such sale would result in a net
gain or loss depending on whether the amount received on the sale is more or
less than the premium and other transaction costs paid on the call or put
which is sold.
         The Fund may close out its position in a futures contract or an
option on a futures contract only by entering into an offsetting transaction
on the exchange on which the position was established and only if there is a
liquid secondary market for the futures contract. If it is not possible to
close a futures position entered into by the Fund, it could be required to
make continuing daily cash payments to meet margin requirements in the event
of adverse price movements. In such situations, if the Fund has insufficient
cash, it may have to sell portfolio securities to meet daily variation margin
requirements at a time when it would be disadvantageous to do so. The
inability to close futures or options positions could have an adverse effect
on the Fund. There is also risk of loss by the Fund of margin deposits in the
event of bankruptcy of a broker with whom the Fund has an open position in a
futures contract. The correlation is imperfect between movements in the prices
of futures or option contracts, and the movements of prices of the securities
which are subject to the hedge. If the Fund used a futures or options contract
to hedge against a decline in the market, and the market later advances (or
vice-versa), the Fund may suffer a greater loss than if it had not hedged.
         Engaging in transactions in financial futures contracts involves
certain risks, such as the possibility of an imperfect correlation between
futures market prices and cash market prices and the possibility that the
Advisor or Subadvisor could be incorrect in its expectations as to the
direction or extent of various interest rate movements, in which case the
Fund's return might have been greater had hedging not taken place. There is
also the risk that a liquid secondary market may not exist. The risk in
purchasing an option on a financial futures contract is that the fund will
lose the premium it paid. Also, there may be circumstances when the purchase
of an option on a financial futures contract would result in a loss to the
Fund while the purchase or sale of the contract would not have resulted in a
loss.
         The Fund will not purchase or sell any financial futures contract or
related option if, immediately thereafter, the sum of the cash or U.S.
Treasury bills committed with respect to its existing futures and related
options positions and the premiums paid for related options would exceed 5% of
the market value of its total assets. At the time of purchase of a futures
contract or a call option on a futures contract, an amount of cash, U.S.
Government securities or other appropriate liquid debt or equity securities
equal to the market value of the futures contract, minus the Fund's initial
margin deposit with respect thereto, will be deposited in a segregated account
with the Fund's custodian bank to collateralize fully the position and thereby
ensure that it is not leveraged. The extent to which the Fund may enter into
financial futures contracts and related options may also be limited by the
requirements of the Internal Revenue Code of 1986 for qualification as a
regulated investment company.
         Warrants and stock rights are almost identical to call options in
their nature, use and effect except that they are issued by the issuer of the
underlying security rather than an option writer, and they generally have
longer expiration dates than call options. The Fund may invest up to 5% of its
net assets in warrants and stock rights, but no more than 2% of its net assets
may be invested in warrants and stock rights not listed on the New York Stock
Exchange or the American Stock Exchange.

NONINVESTMENT GRADE (HIGH YIELD/HIGH RISK) DEBT SECURITIES
         The Fund may  invest  up to 5% of its  total  assets  in lower  quality
debt  securities  (generally  those  rated  BB or lower by S&P or Ba or lower by
Moody's),  or in unrated securities  determined by the Advisor to be comparable.
These  securities  have  moderate to poor  protection  of principal and interest
payments  and  have  speculative   characteristics.   These  securities  involve
greater  risk of  default  or price  declines  due to  changes  in the  issuer's
creditworthiness than  investment-grade debt securities.  Because the market for
lower-rated  securities  may be thinner and less  active  than for  higher-rated
securities,  there may be market  price  volatility  for  these  securities  and
limited  liquidity in the resale  market.  This may also impact the Fund's Board
of  Trustees'  ability  to  accurately  value  these  securities  and the Fund's
assets.  Market  prices  for  these  securities  may  decline  significantly  in
periods of general  economic  difficulty or rising interest rates.  Unrated debt
securities  may  fall  into  the  lower  quality  category.  Unrated  securities
usually are not  attractive to as many buyers as are rated  securities,  and any
adverse   publicity   and  investor   perceptions,   whether  or  not  based  on
fundamental analysis, may make them less marketable.
         The Fund will not  purchase any  securities  rated lower than C (for an
explanation of Corporate Bond and Commercial Paper ratings,  see Appendix).  The
quality   limitation   set  forth  in  the   investment   policy  is  determined
immediately upon the Fund's  acquisition of a security.  Accordingly,  any later
change in ratings may not be considered when  determining  whether an investment
complies with the Fund's investment  policy.  Credit ratings evaluate the safety
of principal and interest payments, not market value risk of the securities.
         When  purchasing  high-yielding  securities,   rated  or  unrated,  the
Subadvisor  prepares  its own  careful  credit  analysis  to attempt to identify
those issuers whose financial  condition is adequate to meet future  obligations
or is expected to be adequate in the future.  The Subadvisor  also  continuously
monitors  the  issuers  of the  securities  in the  Fund to  assure  that  their
financial    condition    continues   to   be   adequate.    Through   portfolio
diversification  and credit analysis,  investment risk can be reduced,  although
there can be no assurance that losses will not occur.

LENDING PORTFOLIO SECURITIES
         Although it does not  currently  intend to do so, the Fund may lend its
portfolio  securities  to  member  firms  of the New  York  Stock  Exchange  and
commercial  banks with  assets of one  billion  dollars  or more.  Loans must be
secured  continuously  in the  form of cash  or  cash  equivalents  such as U.S.
Treasury  bills;  the amount of the collateral  must on a current basis equal or
exceed the market value of the loaned  securities,  and the Fund must be able to
terminate  such loans upon notice at any time.  The Fund will exercise its right
to  terminate  a  securities  loan in order to  preserve  its right to vote upon
matters of importance affecting holders of the securities.
         The  advantage of such loans is that the Fund  continues to receive the
equivalent  of the  interest  earned or  dividends  paid by the  issuers  on the
loaned  securities  while  at the  same  time  earning  interest  on the cash or
equivalent  collateral  which may be  invested  in  accordance  with the  Fund's
investment objective, policies and restrictions.
         Securities  loans  are  usually  made  to   broker-dealers   and  other
financial  institutions  to facilitate  their  delivery of such  securities.  As
with any  extension  of  credit,  there  may be risks of delay in  recovery  and
possibly  loss of rights in the loaned  securities  should the  borrower  of the
loaned  securities fail  financially.  However,  the Fund will make loans of its
portfolio  securities  only to those  firms  the  Advisor  or  Subadvisor  deems
creditworthy and only on terms the Advisor  believes should  compensate for such
risk.  On  termination  of the loan,  the  borrower is  obligated  to return the
securities to the Fund.  The Fund will  recognize any gain or loss in the market
value of the  securities  during the loan  period.  The Fund may pay  reasonable
custodial fees in connection with the loan.

                            INVESTMENT RESTRICTIONS

Fundamental Investment Restrictions
         The  Fund has  adopted  the  following  investment  restrictions  which
cannot be changed  without  the  approval  of the  holders of a majority  of the
outstanding  shares of the Fund.  As defined in the  Investment  Company  Act of
1940,  this  means the  lesser of the vote of (a) 67% of the  shares of the Fund
at a meeting  where  more than 50% of the  outstanding  shares  are  present  in
person or by proxy or (b) more than 50% of the  outstanding  shares of the Fund.
The Fund may not:

         1.       With  respect  to 75% of its total  assets,  purchase
         securities  of any  issuer  (other  than  obligations  of,  or
         guaranteed by, the United States  Government,  its agencies or
         instrumentalities)  if,  as a  result,  more  than  5% of  the
         value of its total assets would be invested in  securities  of
         that issuer.
         2.       Concentrate  25% or more of the  value  of its  total
         assets in any one industry;  provided,  however, that there is
         no  limitation  with  respect to  investments  in  obligations
         issued or guaranteed  by the United  States  Government or its
         agencies  and  instrumentalities,  and  repurchase  agreements
         secured thereby.
         3.       Make  loans  of  more  than  one-third  of the  total
         assets of the Fund,  other than  through the purchase of money
         market  instruments  and  repurchase   agreements  or  by  the
         purchase of bonds,  debentures  or other debt  securities,  or
         the  lending  of  portfolio  securities  as  detailed  in  the
         prospectus,  or as  permitted by law. The purchase by the Fund
         of all or a  portion  of an issue  of  publicly  or  privately
         distributed   debt   obligations   in   accordance   with  its
         investment  objective,  policies and  restrictions,  shall not
         constitute the making of a loan.
         4.       Underwrite the  securities of other  issuers,  except
         as permitted by the Board of Trustees  within  applicable law,
         and  except  to  the  extent  that  in  connection   with  the
         disposition  of its  portfolio  securities,  the  Fund  may be
         deemed to be an underwriter.
         5.       Issue  senior   securities  or  borrow  money  in  an
         amount exceeding  one-third of the Fund's total assets,  or as
         permitted   by  law.   In  order  to  secure   any   permitted
         borrowings under this section,  the Fund may pledge,  mortgage
         or hypothecate its assets.
         6.       Except as required  in  connection  with  permissible
         options, futures and       commodity  activities  of the Fund,
         invest in commodities,  commodity futures  contracts,  or real
         estate,  although  it  may  invest  in  securities  which  are
         secured  by  real   estate  or  real  estate   mortgages   and
         securities  of issuers  which  invest or deal in  commodities,
         commodity  futures,  real estate or real estate  mortgages and
         provided   that  it  may   purchase  or  enter  into   futures
         contracts and options on futures  contracts,  foreign currency
         futures,          interest rate futures and options thereon.

NONFUNDAMENTAL INVESTMENT RESTRICTIONS
         The Fund has adopted the following  operating  (i.e.,  non-fundamental)
investment  policies  and  restrictions  which  may be  changed  by the Board of
Trustees without shareholder approval. The Fund may not:

         7.       Invest,  in the  aggregate,  more than 15% of its net
         assets  in  illiquid   securities.   Purchases  of  securities
         outside  the  U.S.  that  are not  registered  with the SEC or
         marketable in the U.S. are not per se illiquid.
         8.       With respect to 75% of its total  assets,  invest 10%
         or more of its  assets  in the  voting  securities  of any one
         issuer.

         For  purposes  of  the  Fund's   concentration   policy   contained  in
restriction   (2),  above,   the  Fund  classifies  the  respective   industries
according to a revised  version of William  O'Neil's  Investor's  Business Daily
industry classification.
         Any  investment  restriction  (with the  exception  of  borrowings  and
illiquid  holdings) which involves a maximum  percentage of securities or assets
shall not be  considered  to be violated  unless an excess  over the  applicable
percentage   occurs   immediately   after  an   acquisition   of  securities  or
utilization of assets and results therefrom.

                      DIVIDENDS, DISTRIBUTIONS, AND TAXES

         The Fund declares and pays dividends  from net investment  income on an
annual  basis.  Distributions  of  realized  net  capital  gains,  if  any,  are
normally  paid once a year;  however,  the Fund does not intend to make any such
distributions  unless available capital loss carryovers,  if any, have been used
or have expired. Dividends and distributions paid may differ among the classes.
         Investors  should note that the Internal  Revenue Code (the "Code") may
require  investors  to exclude the initial  sales  charge,  if any,  paid on the
purchase  of Fund  shares  from the tax basis of those  shares if the shares are
exchanged  for shares of another  Calvert Group Fund within 90 days of purchase.
This  requirement  applies  only to the extent that the payment of the  original
sales  charge on the shares of the Fund causes a reduction  in the sales  charge
otherwise  payable  on the shares of the  Calvert  Group  Fund  acquired  in the
exchange,  and investors may treat sales charges  excluded from the basis of the
original shares as incurred to acquire the new shares.
         The Fund is required to withhold 31% of any  dividends  and 31% of each
redemption  transaction  occurring in the 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 Code because of  underreporting
(however,  failure to provide  certification  as to the  application  of section
3406(a)(1)(C)  will  result  only in backup  withholding  on  dividends,  not on
redemptions);  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
withheld.
         The Fund is  required  to report to the  Internal  Revenue  Service the
following  information  with  respect to each  redemption  transaction:  (a) the
shareholder's  name,  address,   account  number  and  taxpayer   identification
number;  (b) the  total  dollar  value of the  redemptions;  and (c) the  Fund's
identifying CUSIP number.
         Certain  shareholders  are  exempt  from  the  backup  withholding  and
broker  reporting  requirements.   Exempt  shareholders  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;  foreign central
banks of issue.  Non-resident  aliens,  certain foreign partnerships and foreign
corporations  are  generally not subject to either  requirement  but may instead
be  subject  to   withholding   under   sections  1441  or  1442  of  the  Code.
Shareholders  claiming  exemption from backup  withholding and broker  reporting
should call or write the Fund for further information.

                                NET ASSET VALUE

         The public  offering  price of the shares of the Fund is the respective
net asset  value per share  (plus,  for  Class A shares,  the  applicable  sales
charge).  The net asset value  fluctuates  based on the respective  market value
of the  Fund's  investments.  The net asset  value  per share for each  class is
determined  every  business  day at the close of the regular  session of the New
York Stock Exchange  (normally  4:00 p.m.  Eastern time) and at such other times
as may be  necessary  or  appropriate.  The Fund  does 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,  Martin Luther King Day,  Presidents'  Day,
Good Friday,  Memorial Day,  Independence Day, Labor Day,  Thanksgiving Day, and
Christmas  Day. The Fund's net asset value per share is  determined  by dividing
total  net  assets  (the  value  of its  assets  net of  liabilities,  including
accrued expenses and fees) by the number of shares outstanding for that class.
         The  assets  of the Fund are  valued as  follows:  (a)  securities  for
which  market  quotations  are readily  available  are valued at the most recent
closing  price,  mean  between  bid and  asked  price,  or yield  equivalent  as
obtained  from one or more market  makers for such  securities;  (b)  securities
maturing  within  60 days may be valued  at cost,  plus or minus  any  amortized
discount or premium,  unless the Board of  Trustees  determines  such method not
to be  appropriate  under the  circumstances;  and (c) all other  securities and
assets for which  market  quotations  are not readily  available  will be fairly
valued  by the  Advisor  in good  faith  under the  supervision  of the Board of
Trustees.  Equity  options are valued at the last sale price;  if not available,
then the previous  day's sales price is used.  If the bid price is higher or the
asked  price is lower  than the  previous  last sales  price,  the higher bid or
lower  asked  prices may be used.  Exchange  traded  fixed  income  options  are
valued at the last sale price  unless  there is no sale  price,  in which  event
current  prices  provided  by market  makers  are used.  Over-the-counter  fixed
income options are valued based upon current  prices  provided by market makers.
Financial  futures are valued at the settlement  price  established  each day by
the board of trade or exchange on which they are traded.

Net Asset Value and Offering Price Per Share

         Net asset value per share
         ($3,259,982/208,338 shares)                          $15.65
         Maximum sales charge, Class A
         (4.75% of offering price)                              0.78
         Offering price per share, Class A                    $16.43

         Class C net asset value and offering price per share
         ($318,234/20,368 shares)                             $15.62

                          CALCULATION OF TOTAL RETURN

         The Fund may  advertise  "total  return."  Total  return is  calculated
separately  for each class.  Total  return is  computed  per class by taking the
total  number of shares  purchased by a  hypothetical  $1,000  investment  after
deducting any applicable  sales charge,  adding all additional  shares purchased
within the period with reinvested  dividends and distributions,  calculating the
value of those  shares at the end of the period,  and dividing the result by the
initial  $1,000  investment.  For periods of more than one year,  the cumulative
total return is then adjusted for the number of years,  taking  compounding into
account, to calculate average annual total return during that period.
         Total return is computed according to the following formula:

                                P(1 + T)n = ERV

where P = a  hypothetical  initial  payment of  $1,000;  T = total  return;  n =
number  of  years;  and ERV = the  ending  redeemable  value  of a  hypothetical
$1,000 payment made at the beginning of the period.
         Total  return is  historical  in nature and is not intended to indicate
future  performance.  All total return  quotations  reflect the deduction of the
maximum  sales  charge  ("return  with  maximum  load"),  except  quotations  of
"return  without  maximum load," which do not deduct sales charge.  Thus, in the
formula  above,  for  return  without  maximum  load,  P  =  the  entire  $1,000
hypothetical  initial  investment  and does not  reflect  the  deduction  of any
sales  charge;  for  return  with  maximum  load,  P  = a  hypothetical  initial
investment  of $1,000 less any sales charge  actually  imposed at the  beginning
of the period for which the performance is being calculated.
         Return for the Funds'  shares for the period  from  inception  (January
31, 1997) to September 30, 1997, are as follows:
                  Class A Shares        Class A Shares        Class C Shares
                  without               Total Return          Total Return
                  Maximum Sales         with Maximum
                  Load                  Sales Load

Since inception   4.33%                 -0.62%                4.13%

         Total  return,  like net asset value per share,  fluctuates in response
to changes in market  conditions.  Performance  for any  particular  time period
should not be considered an indication of future return.

                       PURCHASE AND REDEMPTION OF SHARES

         Investments  in the Fund made by mail,  bank wire or  electronic  funds
transfer,  or through the Fund's branch office or brokers  participating  in the
distribution  of Fund  shares,  are credited to a  shareholder's  account at the
public  offering  price  which is the net  asset  value  next  determined  after
receipt by the Fund, plus the sales charge,  if applicable,  as set forth in the
Fund's  Prospectus.  Certain  Class B and  Class C shares  may be  subject  to a
contingent  deferred  sales  charge  which is  subtracted  from  the  redemption
proceeds (see  Prospectus,  "Calculation  of Contingent  Deferred  Sales Charges
and Waiver of Sales Charges").
         All  purchases  of  Fund  shares  will be  confirmed  and  credited  to
shareholder  accounts  in full and  fractional  shares  (rounded  to the nearest
1/1000th of a share).  Share  certificates  will not be issued unless  requested
in  writing  by the  investor.  No  charge  will be made for  share  certificate
requests.  No certificates  will be issued for fractional  shares. A service fee
of $10.00,  plus any costs  incurred by the Fund,  will be charged to  investors
whose purchase checks are returned for insufficient funds.
         To change  redemption  instructions  already given,  shareholders  must
send a notice  to  Calvert  Group,  with a voided  copy of a check  for the bank
wiring  instructions to be added, to c/o NFDS, P.O. Box 419544,  Kansas City, MO
64141-6544.  If a voided check does not accompany the request,  then the request
must be  signature  guaranteed  by a commercial  bank,  trust  company,  savings
association  or  member  firm  of  any  national  securities   exchange.   Other
documentation may be required from  corporations,  fiduciaries and institutional
investors.
         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  Commission,  or if the  Commission  has ordered a suspension of trading for
the protection of shareholders.
         Redemption  proceeds are normally paid in cash.  However,  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.

                        REDUCED SALES CHARGES (CLASS A)

         The Fund imposes  reduced  sales  charges for Class A shares in certain
situations  in which the  Principal  Underwriter  and the dealers  selling  Fund
shares may  expect to realize  significant  economies  of scale with  respect to
such sales.  Generally,  sales costs do not increase in proportion to the dollar
amount of the shares  sold;  the  per-dollar  transaction  cost for a sale to an
investor  of  shares  worth,  say,  $5,000 is  generally  much  higher  than the
per-dollar  cost for a sale of shares worth  $1,000,000.  Thus,  the  applicable
sales  charge  declines as a percentage  of the dollar  amount of shares sold as
the dollar amount increases.
         When a  shareholder  agrees to make  purchases  of shares over a period
of time  totaling a certain  dollar amount  pursuant to a Letter of Intent,  the
Underwriter  and selling  dealers can expect to realize the  economies  of scale
applicable to that stated goal amount.  Thus,  the Fund imposes the sales charge
applicable to the goal amount.  Similarly,  the  Underwriter and selling dealers
also  experience  cost savings when dealing  with  existing  Fund  shareholders,
enabling the Fund to afford  existing  shareholders  the Right of  Accumulation.
The  Underwriter  and selling  dealers can also expect to realize  economies  of
scale when making sales to the members of certain  qualified  groups which agree
to  facilitate  distribution  of  Fund  shares  to  their  members.  Please  see
"Exhibit A - Reduced Sales  Charges" in the  Prospectus.  For  shareholders  who
intend to  invest at least  $50,000,  a Letter  of  Intent  is  included  in the
Appendix to this Statement of Additional Information.

Officers as a group own less than 1% of the Portfolio's outstanding shares.
Trustees marked with an *, above, are "interested persons" of the Fund, under
the Investment Company Act of 1940.
         Each of the  above  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  and  Silby and Ms.  Krumsiek  are among  the  trustees,  Acacia  Capital
Corporation,  of which only Messrs.  Blatz,  Diehl and Pugh and Ms. Krumsiek are
among the  directors,  Calvert  World Values Fund,  Inc.,  of which only Messrs.
Guffey and Silby and Ms.  Krumsiek  are among the  directors,  and  Calvert  New
World  Fund,  Inc.,  of which  only Ms.  Krumsiek  and Mr.  Martini is among the

         The Audit Committee of the Board is composed of Messrs.  Baird,  Blatz,
Feldman,  Guffey  and Pugh,  and Ms.  Kruvant.  The  Board's  Investment  Policy
Committee is composed of Messrs. Borts, Diehl, Gavian, Rochat and Silby.
         Messrs.  Baird,  Guffey  and  Silby  serve  on the High  Social  Impact
Investments  Committee  which assists the Fund in  identifying,  evaluating  and
selecting  investments  in  securities  that  offer a rate of  return  below the
then-prevailing  market  rate  and that  present  attractive  opportunities  for
furthering the Fund's social criteria.
         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. 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.

**As of December 31, 1997. The Fund Complex consists of nine (9) registered
investment companies.

                       INVESTMENT ADVISOR AND SUBADVISOR

         The Fund's  Investment  Advisor is Calvert  Asset  Management  Company,
Inc., 4550 Montgomery Avenue, 1000N,  Bethesda,  Maryland 20814, a subsidiary of
Calvert  Group Ltd.,  which is a  subsidiary  of Acacia  Mutual  Life  Insurance
Company of Washington, D.C. ("Acacia Mutual").
         The  Advisory  Contract  between  the Fund and the  Advisor was entered
into as of January 30, 1997,  and will remain in effect  indefinitely,  provided
continuance  is  approved  at least  annually  by the vote of the  holders  of a
majority  of the  outstanding  shares of the Fund or by the Board of Trustees of
the Fund; and further provided that such  continuance is also approved  annually
by the vote of a majority  of the  trustees  of the Fund who are not  parties to
the  Contract or  interested  persons of parties to the  Contract or  interested
persons of such parties,  cast in person at a meeting  called for the purpose of
voting on such  approval.  The Contract  may be  terminated  without  penalty by
either party upon 60 days' prior written  notice;  it  automatically  terminates
in the event of its  assignment.  The Fund's  Subadvisor  is Awad &  Associates,
("Subadvisor" or "AWAD").  Pursuant to an Investment  Subadvisory Agreement with
the Advisor, the Subadvisor determines investment selections for the Fund.
         The Fund has  received  an  exemptive  order to permit the Fund and the
Advisor  to  enter  into  and  materially   amend  the  Investment   Subadvisory
Agreement  without  shareholder  approval.  Within 90 days of the  hiring of any
Subadvisor  or  the  implementation  of any  proposed  material  changed  in the
Investment  Subadvisory  Agreement,  the  Fund  will  furnish  its  shareholders
information  about the new Subadvisor or Investment  Subadvisory  Agreement that
would be  included  in a proxy  statement.  Such  information  will  include any
change in such  disclosure  caused by the  addition of a new  Subadvisor  or any
proposed  material change in the Investment  Subadvisory  Agreement of the Fund.
The Fund will meet this condition by providing  shareholders,  within 90 days of
the hiring of the  Subadvisor or  implementation  of any material  change to the
terms of an Investment Subadvisory  Agreement,  with an information statement to
this effect.
         The  Advisor   provides  the  Fund  with  investment   supervision  and
management,  administrative  services,  office  space,  furnishes  executive and
other  personnel  to the  Fund,  and may pay Fund  advertising  and  promotional
expenses.  The  Advisor  reserves  the  right to  compensate  broker-dealers  in
consideration of their  promotional or  administrative  services.  The Fund pays
all  other   administrative  and  operating  expenses,   including:   custodial,
registration,  dividend  disbursing and transfer agency fees;  federal and state
securities   registration  fees;  salaries,   fees  and  expenses  of  Trustees,
executive  officers  and  employees  of  the  Fund,  who  are  not  ''affiliated
persons" of the Advisor or the  Subadvisor  within the meaning of the Investment
Company Act of 1940;  insurance  premiums;  trade  association  dues;  legal and
audit fees;  interest,  taxes and other business fees;  expenses of printing and
mailing  reports,  notices,  prospectuses,  and proxy material to  shareholders;
annual  shareholders'  meeting  expenses;  and brokerage  commissions  and other
costs  associated  with the  purchase  and  sale of  portfolio  securities.  The
Advisor  has  agreed  to  reimburse   the  Fund  for  all  expenses   (excluding
brokerage,  taxes,  interest,  and all or a portion of distribution  and certain
other expenses, to the extent allowed by federal law or regulation).
         Under the  contract,  the  Advisor  provides  investment  advice to the
Fund and oversees its  day-to-day  operations,  subject to direction and control
by the Fund's  Board of  Trustees.  For its  services,  the Advisor  receives an
annual fee of 0.90% of the Fund's average daily net assets.
         For fiscal year 1997, the Fund paid advisory fees of $14,100. The
Advisor may voluntarily defer its fees or assume expenses of the Fund. For
fiscal year 1997, the Advisor reimbursed the Fund $65,410 for fees and
expenses. The Advisor may recapture from (charge to) the Fund (through
December 31, 1999) for such expenses incurred, provided that such recapture
would not cause the Fund's aggregate expenses to exceed the annual expense
limit. The Advisor may voluntarily agree to further defer its fees or assume
Fund expenses from January 1, 1997 through December 31, 1998 ("Additional
Deferral/Assumption Period"). If so, the Advisor may recapture from (charge
to) the Fund for any such expenses incurred during the Additional
Deferral/Assumption Period, provided that such recapture would not cause the
Fund's aggregate expenses to exceed the annual expense limit, and that such
recapture shall be made to the Advisor only from the two-year period from
January 1, 1999 through December 31, 2000. Each year's current advisory fees
(incurred in that year) will be paid in full before any recapture for a prior
year is applied. Recapture then will be applied beginning with the most recent
year first.
         Calvert  Administrative  Services Company ("CASC"), an affiliate of the
Advisor,  has  been  retained  by the  Fund to  provide  certain  administrative
services  necessary to the conduct of its affairs,  including the preparation of
regulatory filings and shareholder  reports,  the daily determination of its net
asset value per share and  dividends,  and the  maintenance of its portfolio and
general  accounting  records.  For  providing  such  services,  CASC receives an
annual fee from the Fund of 0.10% of the Fund's average daily net assets.

                             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  agreement,  CDI is  entitled  to  receive a  distribution  fee
pursuant to the  Distribution  Plan (see  below).  For Class A Shares,  CDI also
receives  the portion of the sales  charge in excess of the dealer  reallowance.
For Class B and Class C Shares, CDI receives any CDSC paid.
         Pursuant to Rule 12b-1 under the  Investment  Company Act of 1940,  the
Fund has adopted  Distribution  Plans (the  "Distribution  Plans") which permits
the  Fund to pay  certain  expenses  associated  with  the  distribution  of its
shares.  Such expenses may not exceed,  on an annual basis,  0.25% of the Fund's
Class A average  daily net assets,  and 1.00% of the Fund's  Class B and Class C
average  daily  net  assets,  respectively.   For  fiscal  year  1997,  Class  A
Distribution  Plan expenses  totaled  $3,390.  Of the Class A Distribution  Plan
expenses  paid in fiscal year 1997,  almost  entirely all of the  expenses  were
used for broker/dealer  compensation.  During the same period,  CDI received net
sales  charges of  $11,744.  For fiscal  year 1997,  Class C  Distribution  Plan
expenses  totaled  $2,104.  Of the  Class  Distribution  Plan  expenses  paid in
fiscal  year  1997,   almost   entirely  all  of  the  expenses  were  used  for
broker/dealer  compensation.  No Class B Distribution Plan expenses were paid in
fiscal year 1997 since there were no Class B Shares outstanding.
         The Fund's  Distribution  Plans were approved 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  Distribution  Plans or
in  any  agreements  related  to  the  Distribution  Plans.  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 Distribution  Plans, the Trustees  considered  various factors including the
amount of the  distribution  expenses.  The Trustees  determined that there is a
reasonable  likelihood  that the  Distribution  Plans will  benefit the Fund and
its shareholders.
         The  Distribution  Plans may be terminated by vote of a majority of the
non-interested  Trustees  who have no direct or indirect  financial  interest in
the  Distribution  Plans, or by vote of a majority of the outstanding  shares of
the Fund. Any change in the Distribution  Plans that would  materially  increase
the distribution  cost to the Fund requires  approval of the shareholders of the
affected  class;  otherwise,  the  Distribution  Plans  may  be  amended  by the
Trustees,  including a majority  of the  non-interested  Trustees  as  described
above.  The Distribution  Plans will continue in effect for successive  one-year
terms provided that such  continuance is  specifically  approved by (i) the vote
of a majority of the Trustees who are not parties to the  Distribution  Plans or
interested  persons  of any  such  party  and who  have no  direct  or  indirect
financial  interest in the  Distribution  Plans, and (ii) the vote of a majority
of the entire Board of Trustees.
         Apart from the  Distribution  Plans,  the Advisor and CDI, at their own
expense,  may incur costs and pay expenses  associated with the  distribution of
shares of the Fund.
         Certain  broker-dealers,  and/or other persons may receive compensation
from the investment advisor,  underwriter,  or their affiliates for the sale and
distribution  of the securities or for services to the Fund.  Such  compensation
my  include  additional  compensation  based on assets  held  through  that firm
beyond the regularly  scheduled  rates, and finder's fee payments to firms whose
representatives   are  responsible  for  soliciting  a  new  account  where  the
accountholder does not choose to purchase through that firm.

                    TRANSFER AND SHAREHOLDER SERVICING AGENT

         National  Financial  Data  Services,  Inc.  ("NFDS"),  a subsidiary  of
State  Street  Bank & Trust,  has been  retained  by the Fund to act as transfer
agent  and  dividend   disbursing   agent.   These   responsibilities   include:
responding  to certain  shareholder  inquiries and  instructions,  crediting and
debiting  shareholder  accounts for purchases and redemptions of Fund shares and
confirming  such  transactions,  and daily updating of  shareholder  accounts to
reflect declaration and payment of dividends.
         Calvert Shareholder  Services,  Inc. ("CSSI"),  a subsidiary of Calvert
Group,  Ltd.,  and  Acacia  Mutual,  has  been  retained  by the  Fund to act as
shareholder  servicing agent.  Shareholder  servicing  responsibilities  include
responding  to  shareholder   inquiries  and   instructions   concerning   their
accounts,  entering  any  telephoned  purchases  or  redemptions  into  the NFDS
system,  maintenance  of  broker-dealer  data,  and preparing  and  distributing
statements  to  shareholders  regarding  their  accounts.   Calvert  Shareholder
Services, Inc. was the sole transfer agent prior to January 1, 1998.
         For  these  services,  NFDS  and  Calvert  Shareholder  Services,  Inc.
receive a fee based on the number of shareholder accounts and transactions.

                               FUND TRANSACTIONS

         Fund  transactions  are  undertaken on the basis of their  desirability
from an investment  standpoint.  Investment  decisions and the choice of brokers
and dealers are made by the Fund's  Advisor and  Subadvisor  under the direction
and supervision of the Fund's Board of Trustees.
         Broker-dealers  who  execute  portfolio  transactions  on behalf of the
Fund are selected on the basis of their  professional  capability  and the value
and  quality  of  their  services.  The Fund may pay  brokerage  commissions  to
broker-dealers  who  provide  the  Fund  with  statistical,  research,  or other
information  and  services.  Notwithstanding  the quality of execution and other
services  provided,  the Fund may pay  commissions  that are  higher  than those
available  elsewhere.  Any such  payments are subject to the criteria of Section
28(e)  of  the  Securities  Exchange  Act  of  1934.  Although  any  statistical
research or other information and services provided by such  broker-dealers  may
be  useful  to the  Advisor  and  the  Subadvisor,  the  dollar  value  of  such
information and services is generally  indeterminable,  and its  availability or
receipt  does not serve  materially  to reduce  the  Advisor's  or  Subadvisor's
normal  research  activities  or expenses.  During  fiscal year 1997,  $3,401 in
aggregate brokerage commissions were paid to broker-dealers.
         The Advisor and  Subadvisor  may also  execute  portfolio  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.
         Depending  upon  market  conditions,   portfolio  turnover,   generally
defined as the  lesser of annual  sales or  purchases  of  portfolio  securities
divided  by the  average  monthly  value  of  the  Fund's  portfolio  securities
(excluding  from both the numerator and the  denominator  all  securities  whose
maturities or  expiration  dates as of the date of  acquisition  are one year or
less), expressed as a percentage. For fiscal year 1997, it was 196%.

                     INDEPENDENT ACCOUNTANT AND CUSTODIANS

         Coopers & Lybrand,  L.L.P.  has been  selected by the Board of Trustees
to serve as  independent  accountant  for fiscal year 1998.  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 portfolios.

                              GENERAL INFORMATION

         The Calvert Fund was  organized as a  Massachusetts  business  trust on
March 15, 1982.  The series of the Fund include  Calvert Income Fund and Calvert
New Vision Small Cap Fund.
         Each share represents an equal  proportionate  interest with each other
share and is  entitled to such  dividends  and  distributions  out of the income
belonging  to such  class  as  declared  by the  Board.  The Fund  offers  three
separate classes of shares:  Class A, Class B and Class C. Each class represents
interests in the same  portfolio  of  investments  but, as further  described in
the  prospectus,  each class is subject to differing sales charges and expenses,
which  differences will result in differing net asset values and  distributions.
Upon any  liquidation  of the Fund,  shareholders  of each class are entitled to
share  pro  rata in the  net  assets  belonging  to that  series  available  for
distribution.
         The Fund will  send its  shareholders  confirmations  of  purchase  and
redemption  transactions,   as  well  as  periodic  transaction  statements  and
unaudited  semi-annual  and audited  annual  financial  statements of the Fund's
investment  securities,  assets  and  liabilities,   income  and  expenses,  and
changes in net assets.
         The  Prospectus  and this  Statement of Additional  Information  do 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 in the Fund's Annual Report to
Shareholders dated September 30, 1997 are expressly incorporated by reference
and made a part of this Statement of Additional Information. A copy of the
Annual Report may be obtained free of charge by writing or calling the Fund.

                                    APPENDIX

CORPORATE BOND AND COMMERCIAL PAPER RATINGS
Corporate Bonds:
Description of Moody's Investors Service Inc.'s/Standard & Poor's bond ratings:
         Aaa/AAA:  Best  quality.  These  bonds  carry  the  smallest  degree of
investment  risk  and  are  generally  referred  to  as  "gilt  edge."  Interest
payments  are  protected  by a large or by an  exceptionally  stable  margin and
principal is secure.  This rating  indicates an extremely strong capacity to pay
principal and interest.
         Aa/AA:  Bonds rated AA also qualify as high-quality  debt  obligations.
Capacity to pay  principal  and interest is very strong,  and in the majority of
instances  they  differ  from AAA issues  only in small  degree.  They are rated
lower than the best bonds because  margins of protection  may not be as large as
in  Aaa  securities,  fluctuation  of  protective  elements  may  be of  greater
amplitude,  or there may be other elements  present which make  long-term  risks
appear somewhat larger than in Aaa securities.
         A/A:  Upper-medium  grade  obligations.   Factors  giving  security  to
principal  and interest  are  considered  adequate,  but elements may be present
which  make the  bond  somewhat  more  susceptible  to the  adverse  effects  of
circumstances and economic conditions.
         Baa/BBB:  Medium grade obligations;  adequate capacity to pay principal
and interest.  Whereas they normally  exhibit  adequate  protection  parameters,
adverse economic  conditions or changing  circumstances  are more likely to lead
to a  weakened  capacity  to pay  principal  and  interest  for  bonds  in  this
category than for bonds in higher rated categories.
         Ba/BB,  B/B,  Caa/CCC,   Ca/CC:  Debt  rated  in  these  categories  is
regarded as  predominantly  speculative with respect to capacity to pay interest
and  repay  principal.  The  higher  the  degree of  speculation,  the lower the
rating.   While  such  debt  will  likely  have  some  quality  and   protective
characteristics,  these are  outweighed  by large  uncertainties  or major  risk
exposure to adverse conditions.
         C/C:  This  rating is only for  income  bonds on which no  interest  is
being paid.
         D:  Debt  in  default;  payment  of  interest  and/or  principal  is in
arrears.

Commercial Paper:
         MOODY'S INVESTORS SERVICE, INC.:
         The Prime rating is the highest  commercial  paper  rating  assigned by
Moody's.  Among the factors  considered by Moody's in assigning  ratings are the
following:  (1)  evaluation  of the  management  of  the  issuer;  (2)  economic
evaluation  of  the  issuer's   industry  or  industries  and  an  appraisal  of
speculative-type  risks which may be inherent in certain  areas;  (3) evaluation
of the issuer's  products in relation to  competition  and customer  acceptance;
(4) liquidity;  (5) amount and quality of long-term  debt; (6) trend of earnings
over a period of ten years;  (7) financial  strength of a parent company and the
relationships  which exist with the issuer;  and (8)  recognition  by management
of  obligations  which  may be  present  or may  arise  as a  result  of  public
interest  questions and  preparations to meet such  obligations.  Issuers within
this Prime  category may be given ratings 1, 2, or 3,  depending on the relative
strengths of these factors.

         STANDARD & POOR'S CORPORATION:
         Commercial paper rated A by Standard & Poor's has the following
characteristics: (i) liquidity ratios are adequate to meet cash requirements;
(ii) long-term senior debt rating should be A or better, although in some
cases BBB credits may be allowed if other factors outweigh the BBB; (iii) the
issuer should have access to at least two additional channels of borrowing;
(iv) basic earnings and cash flow should have an upward trend with allowances
made for unusual circumstances; and (v) typically the issuer's industry should
be well established and the issuer should have a strong position within its
industry and the reliability and quality of management should be unquestioned.
Issuers rated A are further referred to by use of numbers 1, 2 and 3 to denote
the relative strength within this highest classification.

                       GLOSSARY OF PERMITTED INVESTMENTS

The following is a description of permitted investments and other applicable
terms for the Fund:

American Depositary Receipts ("ADRs"): ADRs are securities typically issued by
a U.S. financial institution that evidence ownership interest in a security or
a pool of securities issued by a foreign issuer and deposited with the
depository. ADRs may be available for investment through "sponsored" or
"unsponsored" facilities. A sponsored facility is established jointly by the
issuer of the security underlying the receipt and a depository, whereas an
unsponsored facility may be established by a depository without participation
by the issuer of the receipt's underlying security.
Banker's Acceptance: A bill of exchange or time draft drawn on and accepted by
a commercial bank. It is used by corporations to finance the shipment and
storage of goods and to furnish dollar exchange. Maturities are generally six
months or less.
Certificate of Deposit: A negotiable interest bearing instrument with a
specific maturity. Certificates of deposit are issued by banks and savings and
loan institutions in exchange for the deposit of funds and normally can be
traded in the secondary market prior to maturity. Certificates of deposit
generally carry penalties for early withdrawal.
Commercial Paper: The term used to designate unsecured short-term promissory
notes issued by corporations and other entities. Maturities on these issues
typically vary from a few days to nine months.
Convertible Securities: Securities such as rights, bonds, notes and preferred
stocks which are convertible into or exchangeable for common stocks.
Convertible securities have characteristics similar to both fixed income and
equity securities. Because of the conversion feature, the market value of
convertible securities tends to move together with the market value of the
underlying common stock. As a result, the Portfolio's selection of convertible
securities is based, to a great extent, on the potential for capital
appreciation that may exist in the underlying stock. The value of convertible
securities is also affected by prevailing interest rates, the credit quality
of the issuer, and any call provisions.
Futures Contracts and Options on Futures Contracts: The Fund may enter into
contracts for the purchase or sale of securities. A purchase of a futures
contract means the acquisition of a contractual right to obtain delivery to
the Fund of securities called for by the contract at a specified price during
a specified future month. When a futures contract is sold, the Fund incurs a
contractual obligation to deliver the securities underlying the contract at a
specified price on a specified date during a specified future month. The Fund
may sell stock index futures contracts in anticipation of, or during, a market
decline to attempt to offset the decrease in market value of its common stocks
that might otherwise result; and it may purchase such contracts in order to
offset increases in the cost of common stocks that it intends to purchase.
         The Fund may also purchase and write options to buy or sell futures
contracts. The Fund may write options on futures only on a covered basis.
Options on futures are similar to options on securities except that options on
futures give the purchaser the right, in return for the premium paid, to
assume a position in a futures contract, rather than actually to purchase or
sell the futures contract, at a specified exercise price at any time during
the period of the option. When the Fund enters into a futures transaction it
must deliver to the futures commission merchant selected by the Fund, an
amount referred to as "initial margin." This amount is maintained by the
futures commission merchant in a segregated account at the custodian bank.
Thereafter, a "variation margin" may be paid by the Fund to, or drawn by the
Fund from, such account in accordance with controls set for such accounts,
depending upon changes in the price of the underlying securities to the
futures contract.
Options: The Fund may invest in put and call options for various stocks and
stock indices that are traded on national securities exchanges, from time to
time as the Subadvisor deems to be appropriate. Options will be used for
hedging purposes and will not be engaged in for speculative purposes.
         A put option gives the purchaser of the option the right to sell, and
the writer the obligation to buy, the underlying security at any time during
the option period. A call option gives the purchaser of the option the right
to buy, and the writer of the option the obligation to sell, the underlying
security at any time during the option period. The premium paid to the writer
is the consideration for undertaking the obligations under the option
contract. Although the Fund will engage in option transactions only as hedging
transactions and not for speculative purposes, there are risks associated with
such investment including the following: (i) the success of a hedging strategy
may depend on the ability of the Subadvisor to predict movements in the prices
of the individual securities, fluctuations in markets and movements in
interest rates; (ii) there may be an imperfect correlation between the changes
in market value of the stocks held by the Fund and the prices of options;
(iii) there may not be liquid secondary market for options; and (iv) while the
Fund will receive a premium when it writes covered call options, it may not
participate fully in a rise in the market value of the underlying security.
When writing options (other than covered call options), the Fund must
establish and maintain a segregated account with the Fund's Custodian
containing cash or liquid, high grade debt securities in an amount at least
equal to the market value of the option.
Rabbi Trust: Nonqualified deferred compensation plan which is an irrevocable
trust established by an employer to hold assets to provide deferred
compensation for such employer's employees.
Repurchase Agreements: Agreements by which a person obtains a security and
simultaneously commits to return it to the seller at any agreed upon price
(including principal and interest) on an agreed upon date within a number of
days from the date of purchase. The Fund's Custodian or its agents will hold
the security as collateral for the repurchase agreement. The Fund bears a risk
of loss in the event the other party defaults on its obligations and the Fund
is delayed or prevented from its right to dispose of the collateral securities.
Time Deposit: A non-negotiable receipt issued by a bank in exchange for the
deposit of funds. Like a certificate of deposit, it earns a specified rate of
interest over a definite period of time; however, it cannot be traded in the
secondary market. Time deposits with a withdrawal penalty are considered to be
illiquid securities.
U.S. Government Agency Obligations: Certain Federal agencies such as the
Government National Mortgage Association ("GNMA") have been established as
instrumentalities of the United States Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the United States Government, are either backed by the full
faith and credit of the United States (i.e., GNMA securities) or supported by
the issuing agencies' right to borrow from the Treasury. The issues of other
agencies are supported by the credit of the instrumentality (i.e., Federal
National Mortgage Association securities).
U.S. Government Securities: Bills, notes and bonds issued by the U.S.
Government and backed by the full faith and credit of the United States.
U.S. Treasury Obligations: Bills, notes and bonds issued by the U.S. Treasury,
and separately traded interest and principal component parts of such
obligations that are transferable through the Federal book-entry system known
as Separately Traded Registered Interest and Principal Securities ("STRIPS").
Warrants: Instruments giving holders the right, but not the obligations, to
buy shares of a company at a given price during a specified period.

                                LETTER OF INTENT

                                                                                
Date

Calvert Distributors, Inc.
4550 Montgomery Avenue
Bethesda, MD 20814

Ladies and Gentlemen:

         By signing this Letter of Intent, or affirmatively marking the Letter
of Intent option on my Fund Account Application Form, I agree to be bound by
the terms and conditions applicable to Letters of Intent appearing in the
Prospectus and the Statement of Additional Information for the Fund and the
provisions described below as they may be amended from time to time by the
Fund. Such amendments will apply automatically to existing Letters of Intent.

         I intend to invest in the shares of__________________(Fund or 
Portfolio name) during the thirteen (13) month period from the date of my
first purchase pursuant to this Letter (which cannot be more than ninety (90)
days prior to the date of this Letter or my Fund Account Application Form,
whichever is applicable), an aggregate amount (excluding any reinvestments of
distributions) of at least fifty thousand dollars ($50,000) which, together
with my current holdings of the Fund (at public offering price on date of this
Letter or my Fund Account Application Form, whichever is applicable), will
equal or exceed the amount checked below:

         __ $50,000 __ $100,000 __ $250,000 __ $500,000 __ $1,000,000

         Subject to the conditions specified below, including the terms of
escrow, to which I hereby agree, each purchase occurring after the date of
this Letter will be made at the public offering price applicable to a single
transaction of the dollar amount specified above, as described in the Fund's
prospectus. "Fund" in this Letter of Intent shall refer to the Fund or
Portfolio, as the case may be. No portion of the sales charge imposed on
purchases made prior to the date of this Letter will be refunded.

         I am making no commitment to purchase shares, but if my purchases
within thirteen months from the date of my first purchase do not aggregate the
minimum amount specified above, I will pay the increased amount of sales
charges prescribed in the terms of escrow described below. I understand that
4.75% of the minimum dollar amount specified above will be held in escrow in
the form of shares (computed to the nearest full share). These shares will be
held subject to the terms of escrow described below.

         From the initial purchase (or subsequent purchases if necessary),
4.75% of the dollar amount specified in this Letter shall be held in escrow in
shares of the Fund by the Fund's transfer agent. For example, if the minimum
amount specified under the Letter is $50,000, the escrow shall be shares
valued in the amount of $2,375 (computed at the public offering price adjusted
for a $50,000 purchase). All dividends and any capital gains distribution on
the escrowed shares will be credited to my account.

         If the total minimum investment specified under the Letter is
completed within a thirteen month period, escrowed shares will be promptly
released to me. However, shares disposed of prior to completion of the
purchase requirement under the Letter will be deducted from the amount
required to complete the investment commitment.

         Upon expiration of this Letter, the total purchases pursuant to the
Letter are less than the amount specified in the Letter as the intended
aggregate purchases, Calvert Distributors, Inc. ("CDI") will bill me for an
amount equal to the difference between the lower load I paid and the dollar
amount of sales charges which I would have paid if the total amount purchased
had been made at a single time. If not paid by the investor within 20 days,
CDI will debit the difference from my account. Full shares, if any, remaining
in escrow after the aforementioned adjustment will be released and, upon
request, remitted to me.

         I irrevocably constitute and appoint CDI as my attorney-in-fact, with
full power of substitution, to surrender for redemption any or all escrowed
shares on the books of the Fund. This power of attorney is coupled with an
interest.

         The commission allowed by Calvert Distributors, Inc. to the
broker-dealer named herein shall be at the rate applicable to the minimum
amount of my specified intended purchases.

         The Letter may be revised upward by me at any time during the
thirteen-month period, and such a revision will be treated as a new Letter,
except that the thirteen-month period during which the purchase must be made
will remain unchanged and there will be no retroactive reduction of the sales
charges paid on prior purchases.

         In determining the total amount of purchases made hereunder, shares
disposed of prior to termination of this Letter will be deducted. My
broker-dealer shall refer to this Letter of Intent in placing any future
purchase orders for me while this Letter is in effect.

Exhibit 10


May 1, 1998


Securities and Exchange Commission
Judiciary Plaza
450 Fifth Street, N.W.
Washington, D.C.  20549

         Re:      Exhibit 10, Form N-1A
                  The Calvert Fund - New Vision Small Cap Fund
                  File numbers 2-76510 and 811-3416

Ladies and Gentlemen:

         As Counsel to The Calvert Fund (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. 35 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. 35 to its Registration Statement.


Sincerely,



Susan Walker Bender
Associate General Counsel
