                          INVESTMENT POLICIES AND RISKS
                          -----------------------------

Foreign  Securities
     Investments  in foreign securities may present risks not typically involved
in  domestic  investments.  The  Portfolios  may  purchase  foreign  securities
directly,  on  foreign  markets,  or  those  represented  by American Depositary
Receipts ("ADRs"), or other receipts evidencing ownership of foreign securities,
such  as  International Depository Receipts and Global Depositary Receipts. ADRs
are US dollar-denominated and traded in the US on exchanges or over the counter.
By  investing  in  ADRs  rather  than  directly  in  foreign issuers' stock, the
Portfolios  may  possibly  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.
     Additional  costs  may  be  incurred  in  connection  with  international
investment  since  foreign  brokerage  commissions  and  the  custodial  costs
associated  with  maintaining  foreign portfolio securities are generally higher
than  in  the  United  States.  Fee  expense  may  also  be incurred on currency
exchanges  when the Portfolios change investments from one country to another or
convert  foreign  securities  holdings  into  US  dollars.
     United  States  Government  policies  have  at  times, in the past, through
imposition  of  interest  equalization taxes and other restrictions, discouraged
certain  investments  abroad  by  United  States investors. In addition, foreign
countries  may  impose  withholding  and  taxes  on  dividends  and  interest.
     Investing  in  emerging  markets  in  particular,  those  countries  whose
economies  and  capital  markets  are  not  as  developed  as  those  of  more
industrialized  nations,  carries  its own special risks. Among other risks, the
economies  of  such  countries may be affected to a greater extent than in other
countries  by  price  fluctuations  of  a  single  commodity, by severe cyclical
climactic  conditions,  lack  of  significant  history  in  operating  under  a
market-oriented  economy,  or  by  political  instability,  including  risk  of
expropriation.
     Since  investments  in securities of issuers domiciled in foreign countries
usually  involve  currencies  of  the  foreign countries, and since the Fund may
temporarily hold funds in foreign currencies during the completion of investment
programs,  the  value  of  the  assets  of the Fund as measured in United States
dollars  may be affected favorably or unfavorably by changes in foreign currency
exchange  rates  and  exchange control regulations. For example, if the value of
the foreign currency in which a security is denominated increases or declines in
relation  to the value of the US dollar, the value of the security in US dollars
will  increase  or  decline  correspondingly.  The Portfolios will conduct their
foreign  currency  exchange  transactions either on a spot (i.e., cash) basis at
the  spot  rate  prevailing  in the foreign exchange market, or through entering
into forward contracts to purchase or sell foreign currencies. A forward foreign
currency contract involves an obligation to purchase or sell a specific currency
at  a  future  date  which  may be any fixed number of days from the date of the
contract agreed upon by the parties, at a price set at the time of the contract.
These  contracts  are  traded in the interbank market conducted directly between
currency  traders  (usually  large,  commercial  banks)  and  their customers. A
forward  foreign  currency contract generally has no deposit requirement, and no
commissions  are  charged  at  any  stage  for  trades.
     The Fund may enter into forward foreign currency contracts for two reasons.
First, the Portfolios may desire to preserve the United States dollar price of a
security  when  it enters into a contract for the purchase or sale of a security
denominated  in  a  foreign currency. The Fund may be able to protect themselves
against  possible  losses resulting from changes in the relationship between the
United  States  dollar and foreign currencies during the period between the date
the  security  is  purchased  or  sold  and the date on which payment is made or
received  by  entering  into  a forward contract for the purchase or sale, for a
fixed  amount  of dollars, of the amount of the foreign currency involved in the
underlying  security  transactions.
     Second,  when  the  Advisor  or  Subadvisor believes that the currency of a
particular  foreign  country may suffer a substantial decline against the United
States dollar, the Fund enters into a forward foreign currency contract to sell,
for  a fixed amount of dollars, the amount of foreign currency approximating the
value  of  some  or  all  of  the  Funds' securities denominated in such foreign
currency.  The precise matching of the forward foreign currency contract amounts
and  the  value of the Funds' securities involved will not generally be possible
since  the future value of the securities will change as a consequence of market
movements  between the date the forward contract is entered into and the date it
matures. The projection of short-term currency market movement is difficult, and
the  successful  execution  of  this  short-term  hedging strategy is uncertain.
Although  forward  foreign  currency contracts tend to minimize the risk of loss
due to a decline in the value of the hedged currency, at the same time they tend
to limit any potential gain which might result should the value of such currency
increase.  The  Portfolios  do  not  intend to enter into such forward contracts
under  this  circumstance  on  a  regular  or  continuous  basis.

MARKET RISK
     This is the risk that the value of a Fund's investments will fluctuate as
the stock or bond markets fluctuate and that prices overall will decline over
short or longer-term periods. Market risk also can apply to a particular
industry sector and type of issuer and includes risks associated with investing
substantial amounts in companies located in specific countries or geographic
regions. Factors affecting that sector, issuer, or region could have a major
effect on the value of a Fund's investments. Because the fund may concentrate
25% or more of its assets in the securities of issuers of one industry, it has
increased exposure to any special risks that may effect that industry.

SHORT  SALES
     The  Fund  may  engage  in  short  sales  to gain optimum return on a short
position in a company's stock. A short sale is "against the box" if at all times
during which the short position is open, a Fund owns at least an equal amount of
the  securities  or securities convertible into, or exchangeable without further
consideration  for, securities of the same issue as the securities that are sold
short.

TEMPORARY  DEFENSIVE  POSITIONS
     For  temporary  defensive  purposes  - which may include a lack of adequate
purchase  candidates  or an unfavorable market environment - the Fund may invest
in  cash  or cash equivalents. Cash equivalents include instruments such as, but
not  limited  to, US government and agency obligations, certificates of deposit,
banker's  acceptances, time deposits commercial paper, short-term corporate debt
securities,  and  repurchase  agreements.

REPURCHASE  AGREEMENTS
     The  Fund  may  purchase  debt securities subject to repurchase agreements,
which  are  arrangements  under  which  the Fund buys a security, and the seller
simultaneously  agrees  to repurchase the security at a specified time and price
reflecting  a market rate of interest. The Fund engages in repurchase agreements
in  order to earn a higher rate of return than it could earn simply by investing
in  the  obligation which is the subject of the repurchase agreement. Repurchase
agreements  are  not, however, without risk. In the event of the bankruptcy of a
seller  during the term of a repurchase agreement, a legal question exists as to
whether  the  Fund would be deemed the owner of the underlying security or would
be  deemed  only to have a security interest in and lien upon such security. The
Fund  will  only  engage  in  repurchase  agreements  with recognized securities
dealers  and  banks determined to present minimal credit risk by the Advisor. In
addition, the Fund will only engage in repurchase agreements reasonably designed
to  secure  fully  during  the  term of the agreement the seller's obligation to
repurchase  the  underlying  security  and  will monitor the market value of the
underlying  security  during  the  term  of  the  agreement. If the value of the
underlying  security  declines and is not at least equal to the repurchase price
due  the  Fund  pursuant  to  the agreement, the Fund will require the seller to
pledge additional securities or cash to secure the seller's obligations pursuant
to the agreement. If the seller defaults on its obligation to repurchase and the
value  of  the  underlying  security declines, the Fund may incur a loss and may
incur  expenses  in  selling  the underlying security. Repurchase agreements are
always  for  periods of less than one year. Repurchase agreements not terminable
within  seven  days  are  considered  illiquid.

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

HIGH  SOCIAL  IMPACT  INVESTMENTS

     The  Fund  will  not purchase debt securities other than High Social Impact
Investments  (or  money  market instruments). The High Social Impact Investments
program targets a percentage of the Fund's assets to directly support the growth
of  community-based  organizations  for  the  purposes  of  promoting  business
creation,  housing  development and economic and social development of urban and
rural  communities.  These  securities are unrated - they are expected to be the
equivalent  of  non-investment  grade  debt  securities - that is, lower quality
debt  securities  (generally  those  rated  BB or lower by S&P or Ba or lower by
Moody's,  known  as  "junk  bonds").  These  securities  have  moderate  to poor
protection  of  principal  and  interest  payments  and  have  speculative
characteristics.  See  Appendix  for  a  description of the ratings.) The annual
return on High Social Impact Investments is between 0% and 4%. Thus, rather than
earning  a  higher rate, as would be expected, to compensate for higher the risk
(i.e.,  lower credit quality), they earn a rate of return that is lower than the
rate  currently  earned  by  high  quality U.S. Treasury securities. There is no
secondary  market  for  these  securities

     The  Fund  expects to purchase all of its High Social Impact Investments in
notes  issued  by  the  Calvert  Social  Investment  Foundation,  a  non-profit
organization, legally distinct from Calvert Group, organized as a charitable and
educational  foundation  for  the  purpose  of  increasing  public awareness and
knowledge  of  the  concept  of  socially responsible investing.  The Foundation
prepares  its own careful credit analysis to attempt to identify those community
development  issuers  whose  financial  condition  is  adequate  to  meet future
obligations  or  is  expected  to  be  adequate in the future. Through portfolio
diversification  and  credit  analysis, investment risk can be reduced, although
there can be no assurance that losses will not occur. The Foundation maintains a
certain  required level of capital upon which the Fund could rely if a note were
ever  to  default.

NON-INVESTMENT  GRADE  DEBT  SECURITIES
     Non-investment  grade  debt  securities  are  lower quality debt securities
(generally  those  rated  BB or lower by S&P or Ba or lower by Moody's, known as
"junk bonds." These securities have moderate to poor protection of principal and
interest  payments  and  have  speculative  characteristics.  See Appendix for a
description of the ratings.) 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.  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 rated securities are, which may make them less
marketable.
     The  quality  limitation  set  forth  in  the  Fund's  investment policy is
determined  immediately  after  the  Fund's  acquisition  of  a  given security.
Accordingly, any later change in ratings will not be considered when determining
whether  an  investment  complies  with  the  Fund's  investment  policy.
     When purchasing non-investment grade debt securities, rated or unrated, the
Advisors  prepare their 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. Through portfolio diversification and
credit  analysis,  investment  risk  can  be  reduced,  although there can be no
assurance  that  losses  will  not  occur.

DERIVATIVES
     The Fund can use various techniques 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
either  as  substitution or as protection against an adverse move in the Fund to
adjust  the  risk  and return characteristics of the Fund. If the Advisor and/or
Subadvisor  judges market conditions incorrectly or employs a strategy that does
not  correlate  well  with  a  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 a Fund and may involve a
small  investment  of  cash  relative  to  the  magnitude  of  the risk assumed.
Derivatives  are  often  illiquid.

OPTIONS  AND  FUTURES  CONTRACTS
     The  Funds  may,  in  pursuit  of  their  respective investment objectives,
purchase  put and call options and engage in the writing of covered call options
and secured put options on securities which meet the Fund's social criteria, and
employ a variety of other investment techniques. Specifically, the Fund may also
engage  in  the  purchase  and  sale  of  stock  index future contracts, foreign
currency futures contracts, interest rate futures contracts, and options on such
futures,  as  described  more  fully  below.
     The  Fund  may  engage  in  such  transactions  only  to hedge the existing
positions  in  the respective Portfolios (or for Managed Index, for liquidity or
to  hedge  cash  exposure).  They  will  not engage in such transactions for the
purposes of speculation or leverage. Such investment policies and techniques may
involve  a  greater  degree  of  risk  than  those inherent in more conservative
investment  approaches.
     The  Fund  may  write "covered options" on securities in standard contracts
traded  on  national  securities  exchanges.  The Fund may write such options in
order  to  receive  the  premiums from options that expire and to seek net gains
from  closing  purchase  transactions  with  respect  to  such  options.

Put  and  Call  Options. The Fund may purchase put and call options, in standard
contracts  traded  on  national  securities  exchanges, on securities of issuers
which  meet the Fund's social criteria. The Fund will purchase such options only
to  hedge  against changes in the value of securities the Fund holds and not for
the purposes of speculation or leverage. By buying a put, the Fund has the right
to  sell  the  security  at  the  exercise price, thus limiting its risk of loss
through a decline in the market value of the security until the put expires. The
amount  of  any  appreciation  in  the  value of the underlying security will be
partially  offset  by  the amount of the premium paid for the put option and any
related  transaction costs. Prior to its expiration, a put option may be sold in
a  closing  sale transaction and any profit or loss from the sale will depend on
whether  the  amount  received is more or less than the premium paid for the put
option  plus  the  related  transaction  costs.
     The  Fund  may purchase call options on securities which they may intend to
purchase  and  which  meet  the Fund's social criteria. Such transactions may be
entered  into in order to limit the risk of a substantial increase in the market
price  of  the  security  which  the  Fund  intends  to  purchase.  Prior to its
expiration,  a call option may be sold in a closing sale transaction. Any profit
or  loss  from such a sale will depend on whether the amount received is more or
less  than  the  premium  paid  for the call option plus the related transaction
costs.

Covered  Options.  The  Fund  may  write only covered options on equity and debt
securities  in  standard contracts traded on national securities exchanges. This
means  that, in the case of call options, so long as a Portfolio is obligated as
the  writer  of a call option, the Fund will own the underlying security subject
to  the option and, in the case of put options, that Portfolio will, through its
custodian,  deposit  and  maintain either cash or securities with a market value
equal  to  or  greater  than  the  exercise  price  of  the  option.
     When  the  Fund  writes a covered call option, the Fund gives the purchaser
the  right  to purchase the security at the call option price at any time during
the  life  of  the  option.  As  the  writer  of the option, the Fund receives a
premium,  less  a commission, and in exchange foregoes the opportunity to profit
from  any increase in the market value of the security exceeding the call option
price.  The  premium  serves  to  mitigate the effect of any depreciation in the
market  value  of  the  security.  Writing covered call options can increase the
income  of the Fund and thus reduce declines in the net asset value per share of
the  Fund  if securities covered by such options decline in value. Exercise of a
call  option  by  the  purchaser  however  will  cause the Fund to forego future
appreciation  of  the  securities  covered  by  the  option.
     When  the  Fund  writes  a covered put option, it will gain a profit in the
amount of the premium, less a commission, so long as the price of the underlying
security  remains  above the exercise price. However, the Fund remains obligated
to purchase the underlying security from the buyer of the put option (usually in
the  event the price of the security falls below the exercise price) at any time
during  the  option  period. If the price of the underlying security falls below
the  exercise price, the Fund may realize a loss in the amount of the difference
between  the exercise price and the sale price of the security, less the premium
received.
     The  Fund  may  purchase  securities which may be covered with call options
solely  on the basis of considerations consistent with the investment objectives
and policies of the Fund.  The Fund's turnover may increase through the exercise
of  a  call option; this will generally occur if the market value of a "covered"
security  increases  and  the  portfolio has not entered into a closing purchase
transaction.
     Risks  Related  to  Options  Transactions.  The  Fund  can  close out their
respective  positions  in  exchange-traded  options  only  on  an exchange which
provides  a  secondary  market  in  such  options.  Although the Fund intends to
acquire  and  write  only  such  exchange-traded  options  for  which  an active
secondary  market appears to exist, there can be no assurance that such a market
will exist for any particular option contract at any particular time. This might
prevent the Fund from closing an options position, which could impair the Funds'
ability  to  hedge  effectively.  The inability to close out a call position may
have an adverse effect on liquidity because the Fund may be required to hold the
securities  underlying  the  option  until  the  option expires or is exercised.

Futures Transactions. The Fund may purchase and sell futures contracts, but only
when,  in  the  judgment of the Advisor, such a position acts as a hedge against
market  changes  which  would  adversely affect the securities held by the Fund.
These  futures  contracts  may  include,  but  are  not limited to, market index
futures  contracts  and  futures  contracts  based on US Government obligations.
     A  futures  contract  is an agreement between two parties to buy and sell a
security on a future date which has the effect of establishing the current price
for  the  security.  Although  futures  contracts  by their terms require actual
delivery  and  acceptance  of securities, in most cases the contracts are closed
out  before  the  settlement  date  without  the making or taking of delivery of
securities. Upon buying or selling a futures contract, the Fund deposits initial
margin  with  its custodian, and thereafter daily payments of maintenance margin
are  made  to  and  from  the  executing  broker. Payments of maintenance margin
reflect  changes  in  the  value  of  the  futures contract, with the Fund being
obligated  to  make  such payments if its futures position becomes less valuable
and  entitled  to  receive  such payments if its positions become more valuable.
     The  Fund  may  only  invest in futures contracts to hedge their respective
existing  investment  positions  and  not for income enhancement, speculation or
leverage purposes. Although some of the securities underlying a futures contract
may  not  necessarily  meet  the Fund's social criteria, any such hedge position
taken  by  the  Fund  will  not  constitute  a  direct ownership interest in the
underlying  securities.
     Futures  contracts  are  designed  by  boards of trade which are designated
"contracts  markets"  by  the  Commodity Futures Trading Commission ("CFTC"). As
series  of  a  registered investment company, the Fund is eligible for exclusion
from  the  CFTC's definition of "commodity pool operator," meaning that the Fund
may  invest  in futures contracts under specified conditions without registering
with  the CFTC. Futures contracts trade on contracts markets in a manner that is
similar  to  the way a stock trades on a stock exchange and the boards of trade,
through  their  clearing  corporations,  guarantee performance of the contracts.

Options  on  Futures  Contracts.  The  Fund  may  purchase and write put or call
options  and  sell  call  options  on  futures contracts in which the Fund could
otherwise  invest  and  which are traded on a US exchange or board of trade. The
Fund  may  also  enter into closing transactions with respect to such options to
terminate  an existing position; that is, to sell a put option already owned and
to  buy  a  call  option  to  close a position where the Fund has already sold a
corresponding  call  option.
     The  Fund  may  only  invest in options on futures contracts to hedge their
respective  existing  investment  positions  and  not  for  income  enhancement,
speculation or leverage purposes. Although some of the securities underlying the
futures  contract  underlying  the  option  may  not necessarily meet the Fund's
social criteria, any such hedge position taken by the Fund will not constitute a
direct  ownership  interest  in  the  underlying  securities.
     An  option  on  a futures contract gives the purchaser the right, in return
for the premium paid, to assume a position in a futures contract-a long position
if  the  option  is  a  call  and  a  short position if the option is a put-at a
specified  exercise  price at any time during the period of the option. The Fund
will  pay  a premium for such options purchased or sold. In connection with such
options  bought  or sold, the Fund will make initial margin deposits and make or
receive maintenance margin payments which reflect changes in the market value of
such  options. This arrangement is similar to the margin arrangements applicable
to  futures  contracts  described  above.

Put  Options  on  Futures  Contracts.  The  purchase  of  put options on futures
contracts  is  analogous to the sale of futures contracts and is used to protect
the  portfolios  against the risk of declining prices. The Fund may purchase put
options and sell put options on futures contracts that are already owned by that
Portfolio. The Fund will only engage in the purchase of put options and the sale
of  covered  put  options  on  market  index  futures  for  hedging  purposes.

Call Options on Futures Contracts. The sale of call options on futures contracts
is  analogous  to  the sale of futures contracts and is used to protect the Fund
against  the  risk  of declining prices. The purchase of call options on futures
contracts  is analogous to the purchase of a futures contract. The Fund may only
buy call options to close an existing position where the Fund has already sold a
corresponding call option, or for a cash hedge. The Fund will only engage in the
sale  of  call  options  and  the  purchase of call options to cover for hedging
purposes.

Writing  Call  Options  on  Futures  Contracts.  The  writing of call options on
futures  contracts  constitutes  a partial hedge against declining prices of the
securities  deliverable  upon  exercise  of the futures contract. If the futures
contract  price  at expiration is below the exercise price, the Fund will retain
the full amount of the option premium which provides a partial hedge against any
decline  that  may  have  occurred  in  the  Fund's  securities  holdings.

Risks  of  Options  and Futures Contracts. If the Fund has sold futures or takes
options  positions  to hedge its portfolio against decline in the market and the
market  later  advances,  the Fund may suffer a loss on the futures contracts or
options which it would not have experienced if it had not hedged. Correlation is
also  imperfect  between  movements  in  the  prices  of  futures  contracts and
movements  in  prices of the securities which are the subject of the hedge. Thus
the  price of the futures contract or option may move more than or less than the
price  of  the securities being hedged. Where the Fund has sold futures or taken
options positions to hedge against decline in the market, the market may advance
and  the  value  of the securities held in the Fund may decline. If this were to
occur,  the  Fund  might lose money on the futures contracts or options and also
experience  a  decline  in  the  value  of  its  securities.
     The  Fund  can  close out futures positions only on an exchange or board of
trade  which  provides  a  secondary  market  in such futures. Although the Fund
intends  to  purchase  or  sell  only such futures for which an active secondary
market appears to exist, there can be no assurance that such a market will exist
for  any  particular futures contract at any particular time. This might prevent
the  Fund  from closing a futures position, which could require the Fund to make
daily  cash  payments with respect to its position in the event of adverse price
movements.
     Options  on  futures  transactions  bear  several  risks  apart  from those
inherent  in  options  transactions  generally.  The Funds' ability to close out
their  options positions in futures contracts will depend upon whether an active
secondary  market  for such options develops and is in existence at the time the
Fund  seeks  to  close  their  positions.  There can be no assurance that such a
market  will develop or exist. Therefore, the Fund might be required to exercise
the  options  to  realize  any  profit.

LENDING  PORTFOLIO  SECURITIES
     The  Portfolios  may  lend  its  securities to member firms of the New York
Stock  Exchange and commercial banks with assets of one billion dollars or more.
Any  such  loans  must  be  secured  continuously  in  the  form of cash or cash
equivalents  such  as  US Treasury bills. The amount of the collateral must on a
current basis equal or exceed the market value of the loaned securities, and the
Portfolios  must  be  able  to terminate such loans upon notice at any time. The
Portfolios  will exercise their right to terminate a securities loan in order to
preserve their right to vote upon matters of importance affecting holders of the
securities.
The  advantage  of  such  loans  is  that the Portfolios 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 Portfolios' 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 Portfolios will make loans of their 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 Portfolio.
The  Portfolio  will  recognize  any  gain  or  loss  in the market value of the
securities  during  the  loan period. The Portfolio may pay reasonable custodial
fees  in  connection  with  the  loan.




                             INVESTMENT RESTRICTIONS
                             -----------------------

FUNDAMENTAL  INVESTMENT  RESTRICTIONS
     The  Fund  has  adopted  the following fundamental investment restrictions.
These  restrictions  cannot  be changed without the approval of the holders of a
majority  of  the  outstanding  shares  of  the  Fund.

(1) The Fund may not make any investment inconsistent with its classification as
a  nondiversified  investment  company  under  the  1940  Act.
(2)  The  Fund  may  concentrate  its  investments  in the securities of issuers
primarily  engaged  in  industries  within  the technology sector and securities
issued  or  guaranteed by the US Government or its agencies or instrumentalities
and  repurchase  agreements  secured  thereby.
(3)  The Fund may not issue senior securities or borrow money, except from banks
for  temporary or emergency purposes and then only in an amount up to 33 1/3% of
the  value  of  a  Portfolio's total assets or as permitted by law and except by
engaging in reverse repurchase agreements, where allowed. In order to secure any
permitted  borrowings  and reverse repurchase agreements under this section, the
Fund  may  pledge,  mortgage  or  hypothecate  its  assets.
(4)  The  Fund  may  not  underwrite  the securities of other issuers, except as
allowed  by  law or to the extent that the purchase of obligations in accordance
with  a  Portfolio's investment objective and policies, either directly from the
issuer,  or  from  an  underwriter for an issuer, may be deemed an underwriting.
(5)  The  Fund may not invest directly in commodities or real estate, although a
Portfolio  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.
(6) The Fund may not make loans, other than through the purchase of money market
instruments and repurchase agreements or by the purchase of bonds, debentures or
other  debt securities, or as permitted by law. The purchase of all or a portion
of  an issue of publicly or privately distributed debt obligations in accordance
with  a  the  Fund's  investment objective, policies and restrictions, shall not
constitute  the  making  of  a  loan.

NONFUNDAMENTAL  INVESTMENT  RESTRICTIONS
     The  Board  of Trustees has adopted the following nonfundamental investment
restrictions.  A  nonfundamental  investment  restriction  can be changed by the
Board  at  any  time  without  a  shareholder  vote.

The  Fund  May  Not:
(1)  Purchase the obligations of foreign issuers or ADRs if more than 45% of the
value  of  the  Portfolio's  net  assets  would  be invested in such securities.
(2)  Purchase  illiquid  securities  if  more  than  15%  of  the  value  of the
Portfolio's  net  assets  would  be  invested  in  such  securities.
(3)  Enter  into  a  futures  contract or an option on a futures contract if the
aggregate  initial  margins  and  premiums required to establish these positions
would  exceed  5%  of  the  Portfolio's  net  assets.
(4) Purchase a put or call option on a security (including a straddle or spread)
if  the  value  of that option premium, when aggregated with the premiums on all
other  options  securities  held  by  the  Portfolio,  would  exceed  5%  of the
Portfolio's  total  assets.
(5)  Enter  into  reverse  repurchase  agreements if the aggregate proceeds from
outstanding  reverse  repurchase  agreements,  when  added  to other outstanding
borrowings  permitted  by  the 1940 Act, would exceed 33 1/3% of the Portfolio's
total  assets. The Portfolio does not intend to make any purchases of securities
if  borrowing  exceeds  5%  of  its  total  assets.

     Any investment restriction that 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.

                          investment selection process
                          ----------------------------

     Investments  in  the  Fund  are  selected  on the basis of their ability to
contribute  to  the  dual  objective  of the Fund, (i.e., those that satisfy the
Fund's  investment  and  social  criteria).  The  Fund has developed a number of
techniques for evaluating the performance of issuers in each of these areas. The
primary  sources of information are reports published by the issuers themselves,
the  reports  of  public  agencies,  and  the  reports  of  groups which monitor
performance  in  particular  areas.  These  sources of information are sometimes
augmented  with  direct  interviews  or  written questionnaires addressed to the
issuers. It should be recognized, however, that there are few generally accepted
measures  by  which  achievement  in  these  areas can be readily distinguished;
therefore,  the development of suitable measurement techniques is largely within
the  discretion  and  judgment  of  the  Advisors  of  the  Fund.
     Candidates  for  inclusion  in  any  particular  class  of  assets are then
examined  according  to  the  social criteria. Issuers are classified into three
categories  of  suitability under the social criteria. In the first category are
those  issuers,  which  exhibit  unusual positive accomplishment with respect to
some  of  the criteria and do not fail to meet minimum standards with respect to
the  remaining  criteria. To the greatest extent possible, investment selections
are  made  from this group. In the second category are those issuers, which meet
minimum  standards  with  respect  to  all  the  criteria  but  do  not  exhibit
outstanding accomplishment with respect to any criterion. This category includes
issuers  which  may  lack an affirmative record of accomplishment in these areas
but  which  are not known by Advisors to violate any of the social criteria. The
third  category  under  the  social  criteria consists of issuers who flagrantly
violate,  or have violated, one or more of those values, for example, a company,
which  repeatedly engages in unfair labor practices. The Fund will not knowingly
purchase  the  securities  of  issuers  in  this  third  category.
     It  should  be  noted  that  the  Fund's  social criteria tend to limit the
availability  of  investment  opportunities  more  than  is customary with other
investment companies. The Advisors of the Fund, however, believe that within the
first  and  second  categories  there are sufficient investment opportunities to
permit full investment among issuers, which satisfy the Fund's social investment
objective.
     To  the  greatest  extent  possible,  the  Advisors  apply  the same social
criteria  to  the  purchase  of  non-equity  securities  as it applies to equity
investments.  With  respect to government securities, the Money Market Portfolio
invests  primarily  in  debt  obligations  issued  or  guaranteed by agencies or
instrumentalities  of  the  Federal  Government  whose  purposes  further or are
compatible  with the Fund's social criteria, such as obligations of the Bank for
Cooperatives  and  the  Student  Loan Marketing Association, rather than general
obligations  of  the  Federal  Government,  such  as  Treasury  securities. Bank
certificates  of deposit, commercial paper, repurchase agreements, and corporate
bonds  are  judged  in  the  same way as a prospective purchase of the bank's or
issuing  company's  common  stock.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES
                       ----------------------------------

     The  Fund  intends to continue to qualify as regulated investment companies
under  Subchapter  M  of  the  Internal Revenue Code. If for any reason the Fund
should  fail  to  qualify, it would be taxed as a corporation at the Fund level,
rather  than  passing  through  its  income  and  gains  to  shareholders.
     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.
Capital  loss  carryforwards  as  of  September  30,  1999, for the Money Market
Portfolio  was  $6,959, Balanced Portfolio was $0, Bond Portfolio was $0, Equity
Portfolio  was  $0,  and  Managed  Index  Portfolio  was  $492,447.
     Generally, dividends (including short-term capital gains) and distributions
are taxable to the shareholder 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.
     The  Fund  is  required  to  withhold  31%  of any reportable dividends and
long-term  capital gain distributions paid and 31% of each reportable redemption
transaction  if:  (a) the shareholder's social security number or other taxpayer
identification  number  ("TIN") is not provided or an obviously incorrect TIN is
provided;  (b)  the shareholder does not certify under penalties of perjury that
the  TIN  provided  is the shareholder's correct TIN and that the shareholder is
not  subject  to  backup withholding under section 3406(a)(1)(C) of the Internal
Revenue  Code  because  of  underreporting  (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.
     In addition, the Fund is required to report to the Internal Revenue Service
the  following information with respect to each redemption transaction occurring
in  the  Fund  (not applicable to Money Market Portfolio): (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, however, exempt from the backup withholding and
broker  reporting  requirements.  Exempt  shareholders  include:  corporations;
financial  institutions;  tax-exempt organizations; individual retirement plans;
the  US,  a  State,  the  District  of  Columbia,  a  US  possession,  a foreign
government,  an international organization, or any political subdivision, agency
or  instrumentality  of  any  of  the  foregoing;  US  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 Internal Revenue Code.
Shareholders  claiming  exemption  from  backup withholding and broker reporting
should  call  or  write  the  Fund  for  further  information.
     Many states do not tax the portion of the Fund's dividends which is derived
from  interest  on  US  Government  obligations.  State  law varies considerably
concerning  the  tax status of dividends derived from US Government obligations.
Accordingly, shareholders should consult their tax advisors about the tax status
of  dividends and distributions from the Fund in their respective jurisdictions.
     Dividends  paid  by  the  Fund  may  be eligible for the dividends received
deduction  available  to corporate taxpayers. Corporate taxpayers requiring this
information  may  contact  Calvert.

                                 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 per share of the Fund is determined every business day as of
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  the total net assets (the value of its
assets net of liabilities, including accrued expenses and fees) by the number of
shares  outstanding  for  each  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.


Total  Return  and  Other  Quotations
     The  Fund  may  advertise  "total  return."  Total  return  is  calculated
separately for each class. Total return differs from yield in that yield figures
measure  only the income component of a the Fund investments, while total return
includes  not  only  the  effect  of income dividends but also any change in net
asset  value,  or  principal  amount,  during the stated period. Total return is
computed 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
Portfolio's  maximum  sales charge, except quotations of "return without maximum
load"  (or  "without  CDSC"  or  "at NAV") which do not deduct sales charge, and
"actual  return,"  which  reflect  deduction  of the sales charge only for those
periods  when  a sales charge was actually imposed. Return without maximum load,
which  will be higher than total return, should be considered only by investors,
such as participants in certain pension plans, to whom the sales charge does not
apply,  or for purposes of comparison only with comparable figures which also do
not  reflect sales charges, such as Lipper averages.  Class I shares do not have
a  sales  charge.

                        purchase and redemption of shares
                        ---------------------------------

     Share  certificates  will  not be issued unless requested in writing by the
investor.     Share  certificates will not be issued unless requested in written
by  the  investor.  If share certificates have been issued, then the certificate
must be delivered to the Fund's transfer agent with any redemption request. This
could  result in delays. If the certificate have been lost, the shareholder will
have  to  pay  to  post  an indemnity bond in case the original certificates are
later presented by another person. No certificates will be issued for fractional
shares.
     The  Fund  has  filed  a  notice  of  election  under  Rule  18f-1 with the
Commission.  The  notice stated that the Fund may honor redemptions that, during
any  90-day  period, exceed $250,000 or 1% of the nest assets value of the Fund,
whichever  is less, by redemptions-in-kind (distributions of a pro rata share of
the  portfolio  securities,  rather  than  cash).
     Fund  shares  shall  be distributed through the distributor and third party
brokers.  See  the  prospectus  for  more  details on purchased and redemptions.

                                   -----------

     The Fund or its affiliates may provide information such as, but not limited
to,  the  economy,  investment  climate,  investment  principles,  sociological
conditions and political ambiance. Discussion may include hypothetical scenarios
or lists of relevant factors designed to aid the investor in determining whether
the  Fund  is  compatible with the investor's goals. The Fund may list portfolio
holdings  or  give  examples  or  securities  that  may have been considered for
inclusion  in  the  Portfolio,  whether  held  or  not.
     The  Fund  or  its  affiliates  may supply comparative performance data and
rankings  from  independent  sources  such as Donoghue's Money Fund Report, Bank

MICHAEL V. YUHAS JR., CPA       OFFICER                         DIRECTOR OF FUND
DOB: 08/04/61                                                  ADMINISTRATION OF
                                                             CALVERT GROUP, LTD.

     The  address  of  Trustee  and  Officers,  unless  otherwise noted, is 4550
Montgomery  Avenue, Suite 1000N, Bethesda, Maryland 20814. Trustees and officers
of  the  Fund  as  a  group  own  less  than 1% of any class of each Portfolio's
outstanding  shares.  Trustees marked with an *, above, are "interested persons"
of  the  Fund,  under  the  Investment  Company  Act  of  1940.

     Mr.  Baird,  Dr.  Mollner, Ms. Adamson, Ms. Jones, and Rev. Morris serve on
the Fund's Audit Committee. Ms. Adamson, Dr. Mollner, and Mr. Silby serve on the
Fund's  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. Ms. Jones, Rev. Morris,
and  Messrs.  Guffey  and  Silby  serve on the Fund's Special Equities Committee
which  assists  the  Fund  in identifying, evaluating, and selecting appropriate
special  equity  investment  opportunities  for  the  Fund.
     The  Advisory  Council  is  a  resource  to  the  Fund's  Board of Trustees
regarding  communications  networks  for  the  Fund  and  the  application  and
refinement  of  the  Fund's  social criteria. The Advisory Council has no power,
authority,  or  responsibility with respect to the management of the Fund or the
conduct  of  the affairs of the Fund. Messrs. Silby, Guffey and Mollner, and Ms.
Krumsiek  serve  as  directors  of  the  Calvert Social Investment Foundation, a
non-profit  organization  formed  to  increase awareness and educate the general
public about the benefits of socially conscious investing. The Foundation is not
directly  affiliated  with  Calvert  Group.
     During  fiscal  1999,  Trustees  of the Fund not affiliated with the Fund's
Advisor  were  paid  $39,781  by  the  Money  Market  Portfolio, $142,545 by the
Balanced  Portfolio,  $15,264  by  the  Bond  Portfolio,  $37,479  by the Equity
Portfolio,  and  $8,228 by the Managed Index Portfolio. Trustees of the Fund not
affiliated  with  the  Advisor  presently  receive  an annual fee of $20,500 for
service  as a member of the Board of Trustees of the Calvert Group of Funds, and
a  fee  of  $750  to $1500 for each regular Board or Committee meeting attended;
such  fees  are  allocated  among  the  respective  Portfolios  based upon their
relative  net  assets.  Trustees who serve only the CSIF Board receive an annual
fee  of  $15,430,  plus  $600  for  each  Board  and Committee meeting attended.
     Trustees  of  the  Fund not affiliated with the Fund's Advisor may elect to
defer  receipt  of all or a percentage of their fees and invest them in any fund
in  the  Calvert Family of Funds through the Trustees Deferred Compensation Plan
(shown  as  "Pension  or  Retirement Benefits Accrued as part of Fund Expenses,"
below).  Deferral  of  the  fees is designed to maintain the parties in the same
position  as  if the fees were paid on a current basis. Management believes this
will have a negligible effect on the Fund's assets, liabilities, net assets, and
net  income  per  share.

portion  of  their  compensation.  As  of  September  30,  1999,  total deferred

$17,765,  $31,559  and  $11,022,  for  each  of  them,  respectively.

                        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").  Acacia is a subsidiary of Ameritas Acacia Mutual
Holding  Company.  Under  the Advisory 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. The Advisor provides the Funds with
investment supervision and management, and office space; furnishes executive and
other  personnel  to  the  Funds;  and  pays  the  salaries  and  fees  of  all
Trustees/Directors  who are employees of the Advisor or its affiliates. The Fund
pays  all  other  administrative  and  operating expenses, including: custodial,
registrar,  dividend disbursing and transfer agency fees; administrative service
fees;  federal  and  state  securities  registration  fees;  salaries,  fees and
expenses of trustees, executive officers and employees of the Fund, and Advisory
Council  members,  who  are  not  employees of the Advisor or of its affiliates;
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 reserves the right to (i) waive all or a part of its fee; (ii)
reimburse  the  Fund for expenses; and (iii) pay broker-dealers in consideration
of  their  promotional  or  administrative  services.
     Turner  Investment  Partners,  Inc.  is 100% employee owned. The subadvisor
receives  a  subadvisory  fee, paid by the Advisor, of 1.00% of the Fund's first
$100  million  of  average  net  assets  and  0.90% of any such assets over $100
million.
     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 change in the Investment Subadvisory
Agreement, the Portfolio 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 Portfolio. The Portfolio 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.

     Calvert  Distributors,  Inc.  ("CDI")  is  the  principal  underwriter  and
distributor  for  the Fund. CDI is an affiliate of the Fund's Advisor. Under the
terms  of its underwriting agreement with the Funds, CDI markets and distributes
the  Fund's  shares  and  is  responsible  for  preparing  advertising and sales
literature,  and  printing  and  mailing  prospectuses to prospective investors.
     Pursuant  to  Rule 12b-1 under the Investment Company Act of 1940, the Fund
has  adopted  Distribution  Plans  (the  "Plans")  which  permit the Fund to pay
certain  expenses  associated with the distribution and servicing of its shares.
Such  expenses  for  Class A shares may not exceed, on an annual basis, 0.25% of
the  Fund's  Class  A  average  daily  net  assets.
     Expenses  under  the Fund's Class B and Class C Plans may not exceed, on an
annual  basis,  1.00%  of  the  Class  B  and  Class C average daily net assets,
respectively.  Class  I  has  no  distribution  plan. Class A Distribution Plans
reimburse  CDI only for expenses it incurs, while the Class B and C Distribution
Plans  compensate  CDI at a set rate regardless of CDI's expenses.  Distribution
Plan expenses may be spent for advertising, printing and mailing of prospectuses
to  persons  who  are  not  already  Fund  shareholders,  compensation  to
broker/dealers,  underwriters,  and salespersons, and, for Class B, interest and
finance  charges.
     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 Plans or in any agreements
related  to  the 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  Plans,  the Trustees considered
various  factors including the amount of the distribution expenses. The Trustees
determined that there is a reasonable likelihood that the Plans will benefit the
Fund  and its shareholders, including economies of scale at higher asset levels,
better  investment  opportunities  and  more  flexibility  in managing a growing
portfolio.
     The  Plans  may  be  terminated by vote of a majority of the non-interested
Trustees  who  have no direct or indirect financial interest in the Plans, or by
vote  of  a  majority  of the outstanding shares of the Fund. If the Fund should
ever switch to a new principal underwriter without terminating the Class B Plan,
the  fee  would  be  prorated between CDI and the new principal underwriter. Any
change  in  the  Plans that would materially increase the distribution cost to a
Class  requires  approval  of the shareholders of the affected class; otherwise,
the  Plans  may  be  amended  by  the  Trustees,  including  a  majority  of the
non-interested  Trustees  as  described above. The 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  Plans  or  interested  persons  of any such party and who have no direct or
indirect financial interest in the Plans, and (ii) the vote of a majority of the
entire  Board  of  Trustees.
     Apart  from the Plans, the Advisor and CDI, at their own expense, may incur
costs  and  pay expenses associated with the distribution of shares of the Fund.
The  Advisor  and/or  CDI  has agreed to pay certain firms compensation based on
sales  of  Fund  shares  or  on  assets  held in those Firm's accounts for their
marketing and distribution of the Fund shares, above the usual sales charges and
service  fees.
     CDI,  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,
pursuant  to  the  Distribution Plans, a distribution fee and a service fee from
the  Fund  based  on  the average daily net assets of each Class. These fees are
paid  pursuant  to  the  Fund's  Distribution  Plan.

 Class  A shares are offered at net asset value plus a front-end sales charge as
follows:

                                   AS A % OF     AS A % OF    ALLOWED TO
AMOUNT OF                          OFFERING     NET AMOUNT    BROKERS AS A % OF
INVESTMENT                         PRICE        INVESTED      OFFERING PRICE
LESS  THAN  $50,000                4.75%        4.99%          4.00%
$50,000 BUT LESS THAN $100,000     3.75%        3.90%          3.00%
$100,000 BUT LESS THAN $250,000    2.75%        2.83%          2.25%
$250,000 BUT LESS THAN $500,000    1.75%        1.78%          1.25%
$500,000 BUT LESS THAN $1,000,000  1.00%        1.01%          0.80%
$1,000,000 AND OVER                0.00%        0.00%          0.00%

     CDI  receives  any  front-end  sales  charge or CDSC paid. A portion of the
front-end  sales  charge  may  be  reallowed  to  dealers.

     Fund  Trustees  and certain other affiliated persons of the Fund are exempt
from  the  sales  charge  since  the  distribution  costs are minimal to persons
already  familiar with the Fund. Other groups (e.g., group retirement plans) are
exempt  due  to  economies  of  scale  in  distribution.  See  Exhibit  A to the
Prospectus.

                    Transfer and shareholder servicing agents
                    -----------------------------------------

     National  Financial  Data  Services, Inc. ("NFDS"), (P.O. Box 19544, Kansas
City,  MO,  64121-9544),  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  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.
     For these services, CSSI receives a fee of $6 per share shareholder account
and  $0.65  per  transaction.

                             portfolio transactions
                             ----------------------

     Fund transactions are undertaken on the basis of their desirability from an
investment  standpoint.  The  Fund's  Advisor  and  Subadvisor  make  investment
decisions  and  the  choice  of  brokers  and  dealers  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  execution  capability and trading expertise
considering,  among  other  factors, the overall reasonableness of the brokerage
commissions, current market conditions, size and timing of the order, difficulty
of  execution,  per share price, market familiarity, reliability, integrity, and
financial  condition,  subject to the Advisor/Subadvisor obligation to seek best
execution. The Advisor or Subadvisor may also consider sales of Fund shares as a
factor  in  the  selection  of  brokers.
     While  the  Fund's  Advisor  and Subadvisor select brokers primarily on the
basis  of  best execution, in some cases they may direct transactions to brokers
based  on  the  quality and amount of the research and research-related services
which  the  brokers  provide  to  them.  These research services include advice,
either  directly  or  through  publications  or  writings,  as  to  the value of
securities,  the advisability of investing in, purchasing or selling securities,
and  the  availability  of  securities  or  purchasers or sellers of securities;
furnishing of analyses and reports concerning issuers, securities or industries;
providing  information  on economic factors and trends; assisting in determining
portfolio  strategy;  providing  computer  software  used  in security analyses;
providing  portfolio  performance  evaluation and technical market analyses; and
providing  other  services  relevant  to the investment decision making process.
Other  such  services are designed primarily to assist the Advisor in monitoring
the  investment  activities  of  the  Subadvisor(s)  of  the Fund. Such services
include  portfolio  attribution  systems,  return-based  style  analysis,  and
trade-execution  analysis.     The  Advisor  and/or  Subadvisor  may also direct
selling  concessions  and/or  discounts  in  fixed-price  offerings for research
services.
     If,  in  the  judgment  of  the Advisor or Subadvisor(s), the Fund or other
accounts  managed  by  them will be benefited by supplemental research services,
they  are  authorized  to  pay brokerage commissions to a broker furnishing such
services  which  are  in  excess  of  commissions  which another broker may have
charged for effecting the same transaction. It is the policy of the Advisor that
such research services will be used for the benefit of the Fund as well as other
Calvert  Group  funds  and  managed  accounts.

                        Personal securities transactions
                        --------------------------------

     The  Fund,  its  Advisor,  and principal underwriter have adopted a Code of
Ethics pursuant to Rule 17j-1 of the Investment Company Act of 1940. The Code of
Ethics  is  designed to protect the public from abusive trading practices and to
maintain  ethical  standards  for  access  persons  as  defined in the rule when
dealing  with  the  public.  The  Code  of  Ethics permits the Fund's investment
personnel  to invest in securities that maybe purchased or held by the Fund. The
Code of Ethics contains certain conditions such as preclearance and restrictions
on  use  of  material  information.

                     independent accountants and custodians
                     --------------------------------------

     Arthur  Anderson LLP has been selected by the Board of Trustees to serve as
independent accountants for fiscal year 2000. State Street Bank & Trust Company,
N.A.,  225  Franklin Street, Boston, MA 02110, serves as custodian of the Fund's
investments.  Allfirst  Financial,  Inc.,  25  South  Charles Street, Baltimore,
Maryland  21203  also  serves as custodian of certain of the Fund's cash assets.
The  custodians  have  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.

                               general information
                               -------------------

     The  Fund  is  an  open-end  management  investment company, organized as a
Massachusetts  business trust on December 14, 1981. The Fund is non-diversified.
The  Fund's  Declaration  of Trust contains an express disclaimer of shareholder
liability  for  acts  or  obligations  of  the  Fund.  The  shareholders  of  a
Massachusetts  business  trust  might,  however, under certain circumstances, be
held personally liable as partners for its obligations. The Declaration of Trust
provides  for  indemnification  and reimbursement of expenses out of Fund assets
for  any  shareholder  held  personally  liable for obligations of the Fund. The
Declaration of Trust also provides that the Fund shall, upon request, assume the
defense  of  any claim made against any shareholder for any act or obligation of
the  Fund  and  satisfy  any  judgment thereon. The Declaration of Trust further
provides that the Fund may maintain appropriate insurance (for example, fidelity
bonding  and errors and omissions insurance) for the protection of the Fund, its
shareholders,  trustees,  officers,  employees and agents to cover possible tort
and  other liabilities. Thus, the risk of a shareholder incurring financial loss
on  account  of  shareholder liability is limited to circumstances in which both
inadequate  insurance  exists  and  the  Fund  itself  is  unable  to  meet  its
obligations.
     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 four separate classes
of  shares:  Class  A,  Class  B,  Class  C  and  Class I. 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  is not required to hold annual shareholder meetings, but special
meetings  may be called for certain purposes such as electing Trustees, changing
fundamental  policies, or approving a management contract. As a shareholder, you
receive  one  vote for each share you own, except that matters affecting classes
differently,  such  as  Distribution  Plans,  will be voted on separately by the
affected  class(es).

                                    --------

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  Ratings:
     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.

                                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 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 CDI 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.
