Y2K Update

Dear Shareholders:
The stock market appears to be on its way to a fifth straight year of 20%
plus returns. The pundits are running out of superlatives. The Dow Jones
Industrial Average produced a total return of 25.86%, closing in on a
record- breaking 10,000 level near the end of the March quarter. The NASDAQ
Composite index, supercharged by the technology sector, generated a total
return of 45.57% over the same six-month period.

The current economic environment for investors is exceedingly positive.
Interest rates and inflationary expectations are low and the US economy
remains in an expansion mode. The world's largest economy is now in its
fifth year of GDP growth in excess of 4%.

Among stocks, the top performers were tightly consolidated by capitalization
range and industry group. Large-capitalization companies and technology
plays fueled most of the advance. In the bond market, long-term US Treasury
securities outperformed other categories substantially.

While investors may be tempted to chase the current trend setters, that
approach comes with increased risk now, given the stock market's high levels
and increased volatility. We encourage investors to make decisions based on
their financial objectives and tolerance for risk. At this point, it would
be a good idea to reevaluate your asset allocation to be sure you are
positioned at a comfortable risk level. If you think change is in order,
your financial professional can suggest strategies that keep you on track to
meet long-term financial objectives without exposing you to undue levels of
risk.

We appreciate your investment in Calvert Group funds and look forward to
providing competitive returns in the months ahead.

Sincerely,

/s/

Barbara J. Krumsiek

High Social Impact Investments
High Social Impact Investments make targeted, direct investments in the
lives of people and their communities. It's helping people like Merlinda. As
a child Merlinda's father told her, "If there's something you want, learn to
make it." So she did. When financial crisis struck, Merlinda took her
grandmother's chili recipe and began cooking. A loan of $500 from ACCION New
Mexico allowed her to can her salsa as well, doubling her sales. Merlinda
says, "that $500 was worth a million." ACCION helps microentrepreneurs start
and grow their businesses in the United States and Latin America. Calvert
has been supporting ACCION to reach out to new entrepreneurs since 1991.

What were the key factors in the performance of the international markets
during the past six months?
The period from October 1998 saw buoyant returns in the international
markets as they recovered from the depths of the crisis precipitated by the
collapse of the emerging markets, at its worst in September. Although the
Latin American region did not turn around until February 1999, the
underlying strength of the US economy and the support this provided to Wall
Street were key factors in the performance of the international markets.
Some of these produced excellent returns over the six months, e.g.; Hong
Kong, 39.4%; Japan, 42.4%; and Singapore, 54.7%.

So how did the Fund perform against its benchmark?
The portfolio return for the period was 20.13%, slightly behind the MSCI
EAFE Index figure of 22.51%.

Tell us more about your strategy during this period.
The key decision on strategy for the period was to reinvest in the markets
of the Far East, which we did in late September. We believed that the
currencies had stabilised, the current accounts had begun to turn around and
that interest rates globally were likely to enter a downward trend. Indeed,
interest rates were cut in late September and again, later. To finance
investments in Asia we sold assets in Europe. This was also the correct
decision since the European markets have underperformed Asia during the last
six months. The other change to strategy implemented during the period was
to build up the portfolio's assets in Japan. Again, this proved to be timely
since the Japanese currency surged during the three months to December and
the market was one of the strongest globally in the first quarter of 1999.

Where do you think Japan will go from here?
Growth in Japan in 1999 will remain poor: consumption is anemic as workers
continue to fear that they will be "downsized" and postpone spending while
the scope for additional public works projects is dwindling as the
government's ability to finance them suffers from the burgeoning budget
deficit. On the positive side, however, the banking system has been
successfully refinanced and, with the mergers currently underway, is moving
to a much firmer footing. Foreign participation in the financial sector will
add to its stability. Secondly, and perhaps more importantly, Japanese
corporations, in increasing numbers, are announcing plans to radically
overhaul and refocus their operations in an attempt to return to
profitability. This is the most important change we have seen in recent
months. If the plans are carried through, it will mark a new beginning in
growth and profitability for the economy. The market has begun to anticipate
this and factor it into equity prices.

What about Europe?
Within Europe, the introduction of the Euro, the single currency for the
eleven participating countries, has been achieved with remarkable success.
Corporations have benefited from commission-free cross border transactions
as well as the predictability of their future revenue stream. The single
currency has also introduced a new level of transparency to corporate
accounts, highlighting the efficient and the less efficient suppliers of
goods and services. This information has stimulated a steady increase in the
level of take-over activity in the region and should, in due course, lead to
improved productivity. The other expectation was that the Euro would become
a new reserve currency. Although there was talk that some governments would
begin to accumulate the Euro as part of their foreign currency reserves,
this trend has not developed. Contrary to expectations, the Euro has
weakened by 8.0% since its launch. This has occurred for several reasons:
lower growth in Euroland versus the dollar region (the US), internal
disputes over finance policy in Germany and ultimately, the mass resignation
of European commissioners under accusations of misconduct. Following the
rate cut in early April, however, there is a belief that the groundwork has
been laid for a revival of growth in the region and a firmer Euro in the
months ahead.

Have markets effectively measured the effects of the Y2K problem?
As the year progresses, we will be conducting research into specific markets
with a view to determining whether systems and processes on a macro scale
are robust enough to withstand the change to the new millennium. The
conclusions of this research will be factored into our investment strategy
in the third and fourth quarter of the year. For several months now, each
time investment analysts from Murray Johnstone have met with the management
of companies in which the Fund is invested, they have asked a series of
questions designed to assess the company's approach to the Y2K problem and
its progress in achieving compliance. We confirm that company management has
systems in place to take them through the millennium and that the company
has tested those systems. If we have any doubts as to the dedication of
companies to the issue, we will monitor their progress and if we remain
unconvinced, we may dispose of the investment.

How have markets resolved the emerging market problems of the last year and
a half?
The other issue has been the approach of investors to the emerging markets
in recent months and their apparent confidence that the difficulties of the
last year and a half have been overcome. Over the period we are reviewing
the conclusion to this question must surely be that investors have taken an
optimistic approach, although it has taken some time for this consensus to
develop. The evidence for this lies in the rapid recovery of the Asian
markets in particular since they hit their lows in September last year. We
have also seen strong markets in Latin America, especially Brazil and
Mexico, once investors were comfortable that the economies had turned the
corner. Looking forward, with an improvement in sentiment towards the sector
and a stable global interest rate background, we see scope for further
progress in these markets.

What is your market outlook for the remainder of 1999?
The key features for the remainder of 1999 will be the rate of growth in the
US and, as a consequence, the Federal Reserve (the Fed) policy on interest
rates; whether growth in Europe begins to pick up; and whether Japan can
indeed return to a growth path. At their recent meeting, the Fed governors
left interest rates unchanged, apparently in the knowledge that growth so
far in 1999 was not proceeding at the same pace as growth in late 1998. Our
own view is that growth in the US will indeed slow through this year as a
result of rising imports and that this will allow the Fed to leave rates as
they currently stand. This will be important for Europe where slower growth
has already led to lower rates. With the combination of progress from the
government and restructuring from corporations in Japan, we believe the
economy can improve and that a pick up in corporate profits will result,
even though domestic sales to unwind cross-holdings will continue. Finally,
with stability in the US and a continuation of low interest rates, we
believe that the outlook for the emerging markets will continue to improve
through the coming months.

Notes to Financial Statements

Note A - Significant Accounting Policies
General: The Calvert World Values International Equity Fund (the "Fund"), a
series of Calvert World Values Fund, Inc., is registered under the
Investment Company Act of 1940 as a non-diversified, open-end management
investment company. The operation of each series are accounted for
separately. The Fund offers four classes of shares of capital stock. Class A
shares are sold with a maximum front-end sales charge of 4.75%. Class B
shares are sold without a front-end sales charge. With certain exceptions,
the Fund will impose a deferred sales charge at the time of redemption,
depending on how long you have owned the shares. Class C shares are sold
without a front-end sales charge. With certain exceptions, the Fund will
impose a deferred sales charge on shares sold within one year. Class B and
Class C shares have higher level of expenses than Class A shares. Effective
March 1, 1999, the Fund began to offer Class I shares of capital stock.
Class I shares require a minimum account balance of $1,000,000. Class I
shares have no front-end or deferred sales charge. Each class has different:
(a) dividend rates, due to difference in Distribution Plan expenses and
other class-specific expenses, (b) exchange privileges and (c)
class-specific voting rights.

Security Valuation: Securities listed or traded on a national securities
exchange are valued at the last reported sale price. Unlisted securities and
listed securities for which the last sale price is not available are valued
at the most recent bid price or based on a yield equivalent obtained from
the securities' market maker. Foreign security prices, furnished by
quotation services in the security's local currency, are translated using
the current U.S. dollar exchange rate. The Fund may invest in securities
whose resale is subject to restrictions. Investments for which market
quotations are not available or deemed inappropriate are valued in good
faith under the direction of the Board of Directors.

In determining fair value, the Board considers all relevant qualitative and
quantitative information available. These factors are subject to change over
time and are reviewed periodically. The values assigned to fair value
investments are based on available information and do not necessarily
represent amounts that might ultimately be realized, since such amounts
depend on future developments inherent in long-term investments. Further,
because of the inherent uncertainty of valuation, those estimated values may
differ significantly from the values that would have been used had a ready
market of the investments existed, and the differences could be material.

At March 31, 1999, $5,176,100, or 2.2% of net assets, were valued by the
Board
of Directors.

Security Transactions and Investment Income: Security transactions are
accounted for on trade date. Realized gains and losses are recorded on an
identified cost basis. Dividend income is recorded on the ex-dividend date
or, in the case of dividends on certain foreign securities, as soon as the
Fund is informed of the ex-dividend date. Interest income, accretion of
discount and amortization of premium are recorded on an accrual basis.
Investment income, expenses and realized and unrealized gains and losses are
allocated to separate classes of shares based upon the relative net assets
of each class.

Foreign Currency Transactions: The Fund's accounting records are maintained
in U. S.

<PAGE>
dollars. For valuation of assets and liabilities on each date of net asset
value determination, foreign denominations are converted into U.S. dollars
using the current exchange rate. Security transactions, income and expenses
are translated at the prevailing rate of exchange on the date of the event.
The effect of changes in foreign exchange rates on securities is included in
the net realized and unrealized gain or loss on securities.

Distributions to Shareholders: Distributions to shareholders are recorded by
the Fund on ex-dividend date. Dividends from net investment income and
distributions from net realized capital gains, if any, are paid at least
annually. Distributions are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles;
accordingly, periodic reclassifications are made within the Fund's capital
accounts to reflect income and gains available for distribution under income
tax regulations.

Estimates: The preparation of the financial statements in conformity with
generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amount of assets and
liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of income and expenses
during the reported period. Actual results could differ from those estimates.

Expense Offset Arrangement: The Fund has an arrangement with its custodian
bank whereby the custodian's and transfer agent's fees may be paid
indirectly by credits earned on the Fund's cash on deposit with the bank.
Such a deposit arrangement is an alternative to overnight investments.

Federal Income Taxes: No provision for federal income or excise tax is
required since the Fund intends to continue to qualify as a regulated
investment company under the Internal Revenue Code and to distribute
substantially all of its earnings.

Note B - Related Party Transactions

Calvert Group and the Year 2000
Plans and Progress

We are now less than a year away from the year 2000, a problematic date for
computer systems coded for two-character year format. Entered as "00," the
year 2000 would be processed as 1900, a mistake that could foul a variety of
date-sensitive transactions.

As your mutual fund sponsor, our goal is make sure there is no interruption
in the level of service you receive. In the summary below, we've outlined
the steps Calvert Group is taking to ensure our systems perform reliably.

Step One-Assess Systems and Software. Develop an Action Plan
In 1997, we identified all systems, operating platforms and software
potentially affected by the millennium bug. These included:

         - Calvert Group systems-portfolio trading, sales contact and
reporting and internal management reporting
         - transfer agency systems-shareholder record-keeping and
transaction processing
         - subadvisor systems-investment accounting
         - other third-party data and service systems.

We also formed a Y2K task force, led by Calvert's vice president of
technology. This group has identified and prioritized our efforts to achieve
year 2000 compliance.

Step Two-Test for Compliance. Repair Systems as Necessary.
Internal systems have been tested. We've made repairs and moved modified
code into production. These systems are now fully compliant. Transfer agency
systems were re-engineered for compliance in 1989. Recent tests indicate
these are, in fact, compliant. The readiness of third-party systems,
including subadvisor systems, has been evaluated. Based on information
received from these groups, we have found no significant obstacles to
compliance.

Step Three-Confirm Compliance. Finalize Contingency Plan.
Testing of transfer agency systems will continue through 1999 to ensure
these remain compliant and continue to interact correctly with external
systems and processes. The transfer agency has established a back-up site,
should main systems fail, and compliance testing of these contingency
measures are also underway. We are developing contingency plans to ensure
that any unforeseen systems failures will not adversely affect our
operations or inconvenience our shareholders.

Y2K Update

Dear Shareholders:
The stock market appears to be on its way to a fifth straight year of 20%
plus returns. The pundits are running out of superlatives. The Dow Jones
Industrial Average produced a total return of 25.86%, closing in on a
record-breaking 10,000 level near the end of the March quarter. The NASDAQ
Composite Index, supercharged by the technology sector, generated a total
return of 45.57% over the same six-month period.

The current economic environment for investors is exceedingly positive.
Interest rates and inflationary expectations are low and the US economy
remains in an expansion mode. The world's largest economy is now in its
fifth year of GDP growth in excess of 4%.

Among stocks, the top performers were tightly consolidated by capitalization
range and industry group. Large-capitalization companies and technology
plays fueled most of the advance. In the bond market, long-term US Treasury
securities outperformed other categories substantially.

While investors may be tempted to chase the current trend setters, that
approach comes with increased risk now, given the stock market's high levels
and increased volatility. We encourage investors to make decisions based on
their financial objectives and tolerance for risk. At this point, it would
be a good idea to reevaluate your asset allocation to be sure you are
positioned at a comfortable risk level. If you think change is in order,
your financial professional can suggest strategies that keep you on track to
meet long-term financial objectives without exposing you to undue levels of
risk.

We appreciate your investment in Calvert Group funds and look forward to
providing competitive returns in the months ahead.

Sincerely,

/s/

Barbara J. Krumsiek

High Social Impact Investments
High Social Impact Investments make targeted, direct investments in the
lives of people and their communities. It's helping people like Merlinda. As
a child Merlinda's father told her, "If there's something you want, learn to
make it." So she did. When financial crisis struck, Merlinda took her
grandmother's chili recipe and began cooking. A loan of $500 from ACCION New
Mexico allowed her to can her salsa as well, doubling her sales. Merlinda,
says, "that $500 was worth a million." ACCION helps microentrepreneurs start
and grow their businesses in the United States and Latin America. Calvert
has been supporting ACCION to reach out to new entrepreneurs since 1991.

of Brown Capital Management Company

How did the Fund perform against its benchmark?
For the six-month period ended March 31, 1999, the S&P 500 turned in a total
return of 27.32%. The S&P 400 Midcap Index, the Fund's benchmark, was up
20.02%, and the Russell 2000 Index, a proxy for small company performance,
up 10.00%. During the past six months, the Calvert Capital Accumulation Fund
produced a total return of 21.57%, outperforming its benchmark by 155 basis
points.

How have different types of stocks or investment styles fared in the market
run up to Dow 10,000?
A handful of largely "big cap" stocks are doing exceptionally well. One of
the most significant developments of this bull market, is the exceptional
"narrowness of performance." In 1998 fewer than 10% of the companies in the
S&P 500 Index accounted for over 75% of the appreciation.

In our view the divergence of performance among the various types of stocks
is the result of exaggerated behavioral patterns by some investors and stock
traders. There is an element of excessive exuberance in response to
"surprisingly" good earnings momentum for the big, easy to own, companies
and excessive punishment for the slightest faltering by anybody else. Many
mid-size and smaller companies continue to post strong revenue and earnings
growth, which is met with total indifference at best. Meanwhile, the
darlings of Wall Street are the ".com" Internet related companies, with or
without earnings of any sort. The very same communications and information
processing technologies that have been important underpinnings of the
economic boom and investment climate have, in our judgment, contributed to
exaggerated market behavior. In today's wired world everyone seems to know
everything at the same time and tries to act as if no one else knows what he
or she knows. The result, all too often, is swift and exaggerated stock
price moves, up and down. It is not clear how these behavioral patterns will
be resolved. Traditionally, and we think appropriately, rational stock
prices are related to general characteristics of the investment environment
and specific factors related to individual companies.

What is the general outlook for equity markets?
Environmental factors remain quite positive. The strength, breadth and depth
of the US economy at this stage of the business cycle are extraordinary.
Employment, production, income and spending are robust. We are in the
longest peacetime economic expansion in US history. While uneven patterns in
other economies are tempering global expansion, they do help to keep
inflationary pressure in check. We see no evidence of an overheated economic
environment but are less than sanguine that a rational case can be made for
continuation of unprecedented investment returns. Our valuation discipline,
which allows for generally higher P/E ratios in periods of low interest
rates, indicates limited near-term appreciation potential for the market's
larger cap indices. A stronger case can be made for individual companies of
any size that maintain growth.

Our valuation discipline treats the five-year Treasury bond as the riskless
asset and assigns appropriate risk premiums to individual companies. The
other crucial variable in our model is the expected earnings growth rate.
Interest rates and risk premiums for many large companies are at
historically low levels and we do not think they would be key catalysts for
near-term price appreciation. Therefore the more important variable in the
current environment is expected earnings growth. In contrast, risk premiums
for midcap companies are at historically high levels and we think they are
likely to be key catalysts for price appreciation over both the short and
long term.

Notes to Financial Statements

Note A -- Significant Accounting Policies

General: The Calvert Capital Accumulation Fund (the "Fund"), a series of
Calvert World Values Fund, Inc., is registered under the Investment Company
Act of 1940 as a non-diversified, open-end management investment company.
The operation of each series are accounted for separately. The Fund offers
four classes of shares of capital stock. Class A shares are sold with a
maximum front-end sales charge of 4.75%. Class B shares are sold without a
front-end sales charge. With certain exceptions, the Fund will impose a
deferred sales charge at the time of redemption, depending on how long you
have owned the shares. Class C shares are sold without a front-end sales
charge. With certain exceptions, the Fund will impose a deferred sales
charge on shares sold within one year of purchase. Class B and Class C
shares have higher level of expenses than Class A shares. Effective March 1,
1999, the Fund began to offer Class I shares of capital stock. Class I
shares require a minimum account balance of $1,000,000. Class I shares have
no front-end or deferred sales charge. Each class has different: (a)
dividend rates, due to Distribution Plan expenses and other class-specific
expenses, (b) exchange privileges; and (c) class-specific voting rights.

Security Valuation: Securities listed or traded on a national securities
exchange are valued at the last reported sale price. Unlisted securities and
listed securities for which the last sale price is unavailable are valued at
the most recent bid price or based on a yield equivalent obtained from the
securities' market maker. Other securities and assets for which market
quotations are not available or deemed inappropriate are valued in good
faith under the direction of the Board of Directors.

Repurchase Agreements: The Fund may enter into repurchase agreements with
recognized financial institutions or registered broker/dealers and, in all
instances, holds underlying securities with a value exceeding the total
repurchase price, including accrued interest. Although risk is mitigated by
the collateral, the Fund could experience a delay in recovering its value
and a possible loss of income or value if the counterparty fails to perform
in accordance with the terms of the agreement.

Futures Contracts: The Portfolio may enter into futures contracts, agreeing
to buy or sell a financial instrument for a set price at a future date. The
Portfolio maintains securities with a value equal to its obligation under
each contract. Initial margin deposits of either cash or securities are made
upon entering into futures contracts; thereafter, variation margin payments
are made or received daily reflecting the change in market value. Unrealized
or realized gains and losses are recognized based on the change in market
value. Risks of futures contracts arise from the possible illiquidity of the
futures markets and the movement in the value of the investment or in
interest rates.

Security Transactions and Investment Income: Security transactions are
accounted for on trade date. Realized gains and losses are recorded on an
identified cost basis. Dividend income is recorded on the ex-dividend date.
Interest income, accretion of discount and amortization of premium are
recorded on an accrual basis. Investment income, expenses and realized and
unrealized gains and losses are allocated to separate classes of shares
based upon the relative net assets of each class.

<PAGE>

Distributions to Shareholders: Distributions to shareholders are recorded by
the Fund on ex-dividend date. Dividends from net investment income and
distributions from net realized capital gains, if any, are paid at least
annually. Distributions are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles;
accordingly, periodic reclassifications are made within the Fund's capital
accounts to reflect income and gains available for distribution under income
tax regulations.

Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of income and expenses
during the reporting period. Actual results could differ from those
estimates.

Expense Offset Arrangements: The Fund has an arrangement with its custodian
bank whereby the custodian's fees may be paid indirectly by credits earned
on the Fund's cash on deposit with the bank. Such a deposit arrangement is
an alternative to overnight investments.

Federal Income Taxes: No provision for federal income or excise tax is
required since the Fund intends to qualify as a regulated investment company
under the Internal Revenue Code and to distribute substantially all of its
earnings.

appreciation aggregated $12,414,944, of which $20,595,336 related to
appreciated securities and $8,180,392 related to depreciated securities.

Note D -- Line of Credit

A financing agreement is in place with all Calvert Group Funds and State
Street Bank and Trust Company ("the Bank"). Under the agreement, the Bank is
providing an unsecured line of credit facility, in the aggregate amount of
$50 million ($25 million committed and $25 million uncommitted), to be
accessed by the Funds for temporary or emergency purposes only. Borrowings
under this facility bear interest at the overnight Federal Funds Rate plus
 .50% per annum. A commitment fee of .10% per annum will be incurred on the
unused portion of the committed facility which will be allocated to all
participating funds. The Fund had no loans outstanding pursuant to this line
of credit at March 31, 1999.

Calvert Group and the Year 2000
Plans and Progress

We are now less than a year away from the year 2000, a problematic date for
computer systems coded for two-character year format. Entered as "00," the
year 2000 would be processed as 1900, a mistake that could foul a variety of
date-sensitive transactions.

As your mutual fund sponsor, our goal is make sure there is no interruption
in the level of service you receive. In the summary below, we've outlined
the steps Calvert Group is taking to ensure our systems perform reliably.

Step One--Assess Systems and Software. Develop an Action Plan
In 1997, we identified all systems, operating platforms and software
potentially affected by the millennium bug. These included:

     Calvert Group systems--portfolio trading, sales contact and reporting
and internal management reporting
     transfer agency systems--shareholder record-keeping and transaction
processing
     subadvisor systems--investment accounting
     other third-party data and service systems.

We also formed a Y2K task force, led by Calvert's vice president of
technology. This group has identified and prioritized our efforts to achieve
year 2000 compliance.

Step Two--Test for Compliance. Repair Systems as Necessary.
Internal systems have been tested. We've made repairs and moved modified
code into production. These systems are now fully compliant. Transfer agency
systems were re-engineered for compliance in 1989. Recent tests indicate
these are, in fact, compliant. The readiness of third-party systems,
including subadvisor systems, has been evaluated. Based on information
received from these groups, we have found no significant obstacles to
compliance.

Step Three--Confirm Compliance. Finalize Contingency Plan.
Testing of transfer agency systems will continue through 1999 to ensure
these remain compliant and continue to interact correctly with external
systems and processes. The transfer agency has established a back-up site,
should main systems fail, and compliance testing of these contingency
measures are also underway. We are developing contingency plans to ensure
that any unforeseen systems failures will not adversely affect our
operations or inconvenience our shareholders.
