Calvert Tax-Free Reserves
Money Market Portfolio

How did the Fund perform?
The Money Market Portfolio's return for the
semi-annual period ending June 30, 1999 was
1.43% (Class O). This was above the 1.24%
return for the average tax-exempt money
market fund tracked by Lipper Analytical
Services, Inc.

How would you characterize the investment
climate over the past six months?
The U.S. economy continued to expand through
the first half of 1999, thanks both to
relentless consumer spending and the
stabilization of economies around the world
after economic crisis in Brazil, Asia, and
Japan.

The task of identifying a sufficient supply
of tax-free money market securities was made
difficult by the low issuance of such
securities and an investor preference to
keep cash in short-term funds. It wasn't
until the tax season that there was an ample
amount of securities to pick and choose
from. In June, the annual issuance of
municipal notes also brought much needed
supply to the market.


What was your strategy for this period?
Since supply was scarce early in the year,
finding fairly-priced securities proved
difficult and we were forced to bide our
time until money flowed out
of tax-exempt funds for April tax payments.
These redemptions forced other fund managers
into selling
securities to raise cash -- which made it
easier to find attractively priced
securities, and
we were presented with an opportunity to
extend the average maturity of the Fund.

Given the likelihood of the Federal Reserve
raising rates toward the end of June, tax
exempt rates were too low on a taxable
equivalent basis when the first one-year
municipal notes were issued earlier in the
month. Therefore,
we did not initially participate in buying
these. In fact, the Federal Reserve
did raise rates a quarter of a point on June
30, 1999. Once enough supply of one-year
notes arrived, the rates on these securities
rose to a more reasonable level and we began
to buy a few of these issues, extending the
Fund's average maturity to 72 days.

<PAGE>

What is your outlook?
Even though the Federal Reserve removed its
bias to raise rates further at the June
Federal Open Market Committee meeting, we
feel the economy will likely continue to
expand and possibly force the Fed to raise
rates again in the second half of 1999. We
are also keeping a close eye on global
economic events that could destabilize world
markets and cause investors to seek the
safety of U.S. money markets. Therefore, we
will keep
the portfolio very liquid in order to react
quickly to changing market conditions.

Calvert Tax-Free Reserves Limited-Term
Portfolio

How did the Fund perform?

The Portfolio performed as it was designed,
that is, to outperform during a rising
interest rate environment. The Fund's six-
month return was 1.35% compared to a 0.72%
return for the average short-term municipal
fund tracked by Lipper Analytical Services,
Inc. The Fund outperformed all other Lipper
tax-exempt fixed income total return
averages during the six-month period ending
June 30, 1999.

What was your strategy for this period?

Short-term municipal rates remained low well
into the first half of the year, due to a
limited supply of new issues and strong
demand for the securities
that did come to market. Since there was no
additional yield to be gained by extending
the Fund, we remained invested in very short
maturity issues.
When taxable rates started to rise, short
municipal rates did not immediately follow.
When it became apparent that the Fed
would raise the Fed funds rate we felt it
was only a matter of time for municipal
rates to follow. With the supply of new
issues in June, tax-exempt rates finally
started to rise to more attractive levels,
and we began to participate more
aggressively by buying securities with a
three-year final maturity.

What is your outlook?

We expect the U. S. economy to remain
strong, which could force the Fed to raise
rates again to preempt inflation. We need to
be wary of the possibility of more rate
increases, and weigh this against periods of
low supply and possible further financial
crises abroad.

Calvert Tax-Free Reserves
Long-Term Portfolio

How did the Fund perform?

For the six month period ending June 30,
1999 the Fund had a return of -1.96% vs. the
Lipper General Municipal Debt Funds Average
of -1.82%, due in large part to our slightly
longer than average duration in the first
quarter.

How would you characterize the investment
climate over the past six months?

As 1998 closed, we anticipated that the
economy would slow to the point where the
Fed would have to cut rates rather than
raise them. Surprisingly, the economy
continued on
its torrid pace of growth. When it became
clear that consumer appetite for goods and
services was continuing to surge, we
shortened our portfolio maturity to better
reflect
our interest rate outlook for the near term.
Late in the second quarter of 1999, the
Federal Reserve adopted a tightening bias,
although the market had already priced in a
50 basis point tightening
and the long bond was trading near six
percent for the first time in almost a year.
By the time the Federal Reserve met on June
30, and increased the Fed funds rate by one
quarter of one percent (25 basis points),
the market was prepared.

What was your strategy for this period?

Going into 1999, we maintained a strategy of
purchasing good quality issues with good
structure -- a strategy that has served us
in the past and should benefit us in the
future. We don't attempt to make bets on any
particular
sector of the market, but high grade general
obligations, housing, and
Puerto Rico Bonds performed the best during
this back up in the market.
We benefited by our exposure to

almost all of the best performing sectors.

What is your outlook?

As stated earlier, the Federal Reserve
raised rates at the end of June as a
precaution against inflation. Having
anticipated that move we shortened our
portfolio. The question that we are now
evaluating is whether subsequent rate hikes
will follow. In any event, we shall remain
nimble, proactive, and alert
to the possibility of rapid shifts in
interest rates.

Notes To Financial Statements

Note A -- Significant Accounting Policies
General: Calvert Tax-Free Reserves (the
"Fund") is registered under the Investment
Company Act of 1940 as as an open-end
management investment company. The Fund is
comprised of five separate portfolios, three
of which
are reported herein; Money Market, Limited-
Term and Long-Term. Money Market and Limited-
Term are registered as diversified
portfolios and Long-Term as a non-
diversified portfolio. The operations of
each portfolio are accounted for separately.
Each Portfolio offers shares of beneficial
interest. Money Market Class O and
Institutional Class shares are sold without
a sales charge. Institutional Class shares
require a minimum account balance of
$1,000,000 and have a lower expense ratio
than Class O Shares. Shares of Limited-Term
and Long-Term are sold with a maximum front-
end sales charge of 1.00% and 3.75%,
respectively.
Effective March 1, 1999, Money Market began
to offer Class T Shares. Class T shares are
sold to investors with brokerage accounts at
The Advisors
Group, Inc. Class T Shares are sold without
a sales charge. Security
Valuation: Municipal securities are valued
utilizing the average of bid prices or at
bid prices based on a matrix system (which
considers such factors as security prices,
yields, maturities and ratings) furnished by
dealers through an independent pricing
service. Securities (including options)
listed or traded on
a national securities exchange are valued at
the last reported sale price. All securities
for Money Market are valued at amortized
cost which approximates market. 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 Trustees.
Options: Long-Term may write or purchase
option securities. The option premium is the
basis for recognition of unrealized or
realized gain or loss on the option. The
cost of securities acquired or the proceeds
from securities sold through the exercise of
the option is adjusted by the amount of the
premium. Risks from writing or purchasing
option securities arise from possible
illiquidity of the options market and the
movement in the value of the investment or
in interest rates. The risk associated with
purchasing options is limited to the premium
originally paid.
Futures Contracts: Long-Term 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.
Interest income, accretion of discount and
amortization
of premium are recorded on an accrual basis.
Investment income and realized gains and
losses are allocated to separate classes of
shares based upon the relative net assets of
each class. Expenses arising in connection
with a class are charged directly to that
class. Expenses common to the classes are
allocated to each class in proportion to
their relative net assets.

<PAGE>

Distributions to Shareholders: Distributions
to shareholders are recorded by the Fund on
ex-dividend date. Dividends from net
investment income are accrued daily and paid
monthly for Money Market; dividends from net
investment income are declared and paid
monthly for Limited-Term and
Long-Term. 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 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.

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.

remediation and testing efforts, please

Dear Shareholders:

Here is your semi-annual report for the six-
month period ending June 30, 1999. For the
most current information regarding the per
formance of your fund, please visit our
recently redesigned Website at
www.calvertgroup.com.

In reviewing our recently redesigned Web
site, you will see that we now offer more
interactive information tools to help you
make the most informed investment decisions.
At www.calvertgroup.com you will find fund
performance, profiles and literature, as
well as a rich array of information on
socially responsible and tax free investing.
Our site also includes company profiles,
issues briefs and our award winning "Know
What You Own(r)" service.

Of special note, we have taken online
disclosure a step further this month by
publishing the entire portfolio holdings for
each of our equity funds. Calvert Group is
the first mutual fund family to provide a
complete listing of holdings on a monthly
basis.

Of course, knowing how a fund has performed
is as important as knowing the companies
that are in a Portfolio. I'm pleased to
report that a significant number of our
funds have received a three-star or better
Morningstar rating for their performance
over the past three years. For performance
over the same time frame, two funds --
Calvert Income Fund and Calvert Tax-Free
Reserves Limited Term Portfolio -- received
Morningstar's superlative five-star rating.1
More detail about your fund's performance is
included in this report.

As always, we encourage investors to make
decisions based on your financial objectives
and tolerance for risk. You should routinely
review your asset allocation to be sure you
are positioned at a comfortable risk level.
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 future.

Sincerely,




Barbara J. Krumsiek
President and CEO
July 20, 1999

Calvert Tax-Free Reserves California Money
Market Portfolio

How did the Fund perform?
The California Money Market Portfolio's
return for the semi-annual period ending
June 30, 1999 was 1.36%. This was above the
1.17% return for the Lipper California Tax
Exempt Money Market Funds Average.

How would you characterize the investment
climate over the past six months?
The U.S. economy continued to expand through
the first half of 1999, thanks both to
relentless consumer spending and the
stabilization of economies around the world
after economic crisis in Brazil, Asia, and
Japan.

The task of identifying a sufficient supply
of tax-free money market securities was made
difficult by the low issuance of such
securities and an investor preference to
keep cash in short-term funds. It wasn't
until the tax season that was there an ample
amount of securities to pick and choose
from. In June, the annual issuance of
municipal notes also brought much needed
supply to the market.

What was your strategy for this period?
Since supply was scarce early in the year,
finding fairly-priced securities proved
difficult and we were forced to bide our
time until money flowed out of tax exempt
funds for April tax payments. These
redemptions forced other fund managers into
selling securities to raise cash -- which
made it easier to find attractively priced
securities, and we were presented with an
opportunity to extend the average maturity
of the Fund.

Given the likelihood of the Federal Reserve
raising rates toward the end of June, tax
exempt rates were too low on a taxable
equivalent basis when the first one-year
municipal notes were issued earlier in the
month. Therefore, we did not initially
participate in buying these. In fact, the
Federal Reserve did raise rates a quarter of
a point on June 30, 1999. Once enough supply
of one-year notes arrived, the rates on
these securities rose to a more reasonable
level and we began to buy a few of these
issues, extending the Fund's average
maturity to 62 days.

<PAGE>

What is your outlook?
Even though the Federal Reserve removed its
bias to raise rates further at the June
Federal Open Market Committee meeting, we
feel the economy will likely continue to
expand and possibly force the Fed to raise
rates again in the second half of 1999. We
are also keeping a close eye on global
economic events that could destabilize world
markets and cause investors to seek the
safety of U.S. money markets. Therefore, we
will keep the portfolio very liquid in order
to react quickly to changing market
conditions.
July 20, 1999

Please remember, this discussion reflects
the views and opinions of Calvert Asset
Management Company at June 30, 1999, the end
of the reporting period. Our strategy and
the Fund's portfolio composition may differ
due to ever-changing market and economic
conditions. While historical performance is
no guarantee of future results, it may give
you a better and more thorough understanding
of our investment decisions and management
philosophy.

Notes To Financial Statements

Note A -- Significant Accounting Policies
General: The California Money Market
Portfolio (the "Portfolio"), a series of
Calvert Tax-Free Reserves (the "Fund"), is
registered under the Investment Company Act
of 1940 as a diversified, open-end
management investment company. The
operations of each series are accounted for
separately. The Portfolio offers shares of
beneficial interest to the public with no
sales charges.

Security Valuation: Securities are valued at
amortized cost which approximates market.

Security Transactions and Investment Income:
Security transactions are accounted for on
trade date. Realized gains and losses are
recorded on an identified cost basis.

Interest income, accretion of discount and
amortization of premium are recorded on an
accrual basis.

Distributions to Shareholders: Distributions
to shareholders are recorded by the
Portfolio on ex-dividend date. Dividends
from net investment income are earned daily
and paid monthly. 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
Portfolio's capital accounts to reflect
income and gains available from 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 Portfolio
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 Portfolios' 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 Portfolio 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 Asset Management Company, Inc. (the
"Advisor") is wholly-owned by Calvert Group,
Ltd. ("Calvert"), which is indirectly wholly-
owned by Ameritas Acacia Mutual Holding
Company. The Advisor provides investment
advisory services and pays the salaries and
fees of officers and affiliated Trustees of
the Fund. For its services, the Advisor
receives a monthly fee based on the
following annual rates of average daily net
assets: .50% on the first $500 million, .45%
on the next $500 million and .40% on the
excess of $1 billion. Under the terms of the
agreement, $220,759 was payable at period
end.

<PAGE>

Calvert Administrative Services Company, an
affiliate of the Advisor, provides
administrative services to the Fund for an
annual fee. The Fund (exclusive of the Money
Market portfolio) pays monthly an annual fee
of $80,000, which is allocated between the
Portfolios based on their relative net
assets. Under the terms of the agreement,
$2,632 was payable at period end.
Calvert Distributors, Inc., an affiliate of
the Advisor, is the distributor and
principal underwriter for the Portfolio.

Calvert Shareholder Services, Inc. (CSSI),
an affiliate of the Advisor, is the
shareholder servicing agent for the Fund.
For its services, CSSI received a fee of
$118,717 for the six months ended June 30,
1999. Under the terms of the agreement,
$19,346 was payable at period end. National
Financial Data Services, Inc. is the
transfer and dividend disbursing agent.

Each Trustee who is not affiliated with the
Advisor received an annual fee of $20,500
plus up to $1,500 for each Board and
Committee meeting attended. Trustee's fees
are allocated to each of the funds served.

Note C -- Investment Activity
The cost of investments owned at June 30,
1999 was substantially the same for federal
income tax and financial reporting purposes.
The table below presents the net capital
loss carryforwards as of December 31, 1998
with expiration dates:

  Capital Loss Carryforwards    Expiration

  $115,124               12/31/03
  351                             12/31/04

Capital loss carryforwards may be utilized
to offset current and future capital gains
until expiration.

As a cash management practice, the Portfolio
may sell or purchase short-term variable
rate demand notes from other Portfolios
managed by the Advisor. All transactions are
executed at independently derived prices.

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 June 30, 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.

remediation and testing efforts, please

     Dear Shareholders:

  Here is your semi-annual report for the
six-month period ending
  June 30, 1999. For the most current
information regarding the       performance
of your fund, please visit our recently
redesigned
Web site at www.calvertgroup.com.

In reviewing our recently redesigned Web
site, you will see that we now
offer more interactive information tools to
help you make the most informed investment
decisions. At www.calvertgroup.com you will
find fund performance, profiles and
literature, as well as a rich array of
information on socially responsible and tax
free investing. Our site also includes
company profiles, issues briefs and our
award winning "Know What You Own(R)"
service.

Of special note, we have taken online
disclosure a step further this month by
publishing the entire portfolio holdings for
each of our equity funds. Calvert Group is
the first mutual fund family to provide a
complete listing of holdings on a monthly
basis.

Of course, knowing how a fund has performed
is as important as knowing the companies
that are in a Portfolio. I'm pleased to
report that a significant number of our
funds have received a three-star or better
Morningstar rating
for their performance over the past three
years. For performance over the
same time frame, two funds -- Calvert Income
Fund and Calvert Tax-Free Reserves Limited
Term Portfolio -- received Morningstar's
superlative five-star rating.1 More detail
about your fund's performance is included in
this report.

As always, we encourage investors to make
decisions based on your financial objectives
and tolerance for risk. You should routinely
review your asset allocation to be sure you
are positioned at a comfortable risk level.
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 future.

Sincerely,




Barbara J. Krumsiek
President and CEO
July 20, 1999

Portfolio

How did the Fund perform?
For the six-month period ending 6/30 the
Fund had a return of  -2.00% vs. the Lipper
Other States Municipal Debt Funds Average of
- -1.18%. This was due to a lessening of
demand for Vermont bonds that had previously
commanded
a premium price. While our duration was in
line with our benchmark, we shortened the
Portfolio slightly going into the second
quarter.

How would you characterize the investment
climate over the past six months?
As 1998 closed, we anticipated that the
economy would slow to the point where the
Fed would have to cut rates rather than
raise them. Surprisingly, the economy
continued on its torrid pace of growth. When
it became clear that consumer appetite for
goods and services was continuing to surge,
we shortened our portfolio to better reflect
our interest rate outlook for the near term.
Late in the second quarter of 1999, the
Federal Reserve adopted a tightening bias,
although the market had already priced in a
50 basis point tightening
and the long bond was trading near six
percent for the first time in almost a year.
By the time the Federal Reserve met on June
30, and increased the fed funds rate by one
quarter of one percent (25 basis points),
the market was prepared.

What was your strategy for this period?
Managing a Vermont fund provides its own set
of unique challenges -- the largest one
being the lack of supply of Vermont issues.
We try to participate
in most every new issue that comes to market
in Vermont, but restrictions placed on
issues to benefit individual investors in
the state have hindered our participation.
In the first quarter of 1999, we were able
to obtain a block of a new Middlebury
College issue -- an attractive purchase
given Middlebury College's fine reputation.
It   historically trades well in the market.
We have been

able to supplement our Vermont portfolio
with tax exempt issues from territories such
as Puerto Rico and Guam.

What is your outlook?
As stated earlier, the Federal Reserve
raised rates at the end of June as a
precaution against inflation. Having
anticipated that move we shortened our
portfolio maturity. The question that we are
now evaluating is whether subsequent rate
hikes will follow. In any event, we shall
remain nimble, proactive, and alert to the
possibility of rapid shifts in interest
rates.

Please remember, this discussion reflects
the views and opinions of Calvert Asset
Management Company at June 30, 1999, the end
of the reporting

portfolio composition may differ due to ever-

While historical performance is no guarantee
of future results, it may give you a better
and more thorough understanding of our
investment
decisions and management philosophy.

Notes To Financial Statements

Note A -- Significant Accounting Policies
General: The Vermont Municipal Portfolio
(the "Portfolio"), a series of Calvert Tax-
Free Reserves (the "Fund"), is registered
under the Investment Company Act of 1940 as
a nondiversified, open-end management
investment company. The operations of each
series are accounted for separately. Shares
of the Portfolio are sold with a maximum
front-end sales charge of 3.75%.
Security Valuation: Municipal securities are
valued utilizing the average of
bid prices or at bid prices based on a
matrix system (which considers such factors
as security prices, yields, maturities and
ratings) furnished by dealers through an
independent pricing service. Securities
(including options) listed
or traded on a national securities exchange
are valued at the last reported sale price.
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 Trustees.
Options: The Portfolio may write or purchase
option securities. The option premium is the
basis for recognition of unrealized or
realized gain or loss on the option. The
cost of securities acquired or the proceeds
from securities
sold through the exercise of the option
is adjusted by the amount of the premium.
Risks from writing or purchasing option
securities arise from possible illiquidity
of the options market and the movement in
the value of the investment or in interest
rates. The risk associated with purchasing
options is limited to the premium originally
paid.
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.
Interest income, accretion of discount and
amortization
of premium are recorded on an accrual basis.
Distributions to Shareholders: Distributions
to shareholders are recorded by the
Portfolio on ex-dividend date. Dividends
from net investment income are paid monthly.
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
Portfolio'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 liabili-

<PAGE>

ties 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 Portfolio
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 Portfolio'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 Portfolio 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 Asset Management Company, Inc. (the
"Advisor") is wholly-owned
by Calvert Group, Ltd. ("Calvert"), which is
indirectly wholly-owned by Ameritas Acacia
Mutual Holding Company. The Advisor provides
investment advisory services and pays the
salaries and fees of officers and affiliated
Trustees of the Portfolio. For its services,
the Advisor receives a monthly fee based on
the following annual rates of average daily
net assets: .60% on the first $500 million,
 .50% on the next $500 million and .40% on
the excess of $1 billion. Under the terms of
the agreement, $31,622 was payable at period
end.
Calvert Administrative Services Company, an
affiliate of the Advisor, provides
administrative services to the Fund for an
annual fee. The Fund (exclusive of the Money
Market portfolio) pays monthly an annual fee
of $80,000, which is allocated between the
Portfolios based on their relative net
assets.
Calvert Distributors, Inc., an affiliate of
the Advisor, is the distributor and
principal underwriter for the Portfolio. The
Distributor received $22,467 as
its portion of commissions charged on sales
of the Portfolio.
Calvert Shareholder Services, Inc. ("CSSI"),
an affiliate of the Advisor, is the
shareholder servicing agent for the
Portfolio. For its services, CSSI received a
fee of $2,527 for the six months ended June
30, 1999. Under the terms of the agreement,
$503 was payable at period end. National
Financial Data Services, Inc., is the
transfer and dividend disbursing agent.
Each Trustee who is not affiliated with the
Advisor received an annual fee of $20,500
plus up to $1,500 for each Board and
Committee meeting attended. Trustee fees are
allocated to each of the funds served.
Note C -- Investment Activity
During the period, purchases and sales of
investments, other than short-term, were
$9,348,010 and $11,661,128, respectively.
The cost of investments owned at June 30,
1999 was substantially the same for federal
income tax and financial reporting purposes.
Net unrealized appreciation aggregated
$110,211, of which $1,178,866 related to
appreciated securities and $1,068,655
related to depreciated securities.
As a cash management practice, the Portfolio
may sell or purchase short-term variable
rate demand notes from other Portfolios
managed by the Advisor. All transactions are
executed at independently derived prices.

<PAGE>

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 June 30 ,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.
