CADRE LIQUID ASSET FUND - U.S. GOVERNMENT SERIES
CIIT CHAIRMAN'S ANNUAL REPORT LETTER
- --------------------------------------------------------------------------------

Dear Shareholders,

As 1999 comes to a close and we stand poised for the new millenium, I cannot
help but reflect on what a year this has been for the Cadre Institutional
Investors Trust (the "Fund"). Since the Fund's inception in 1995, there has not
been such a robust year of development. This year saw the successful
implementation of Y2K readiness projects by our service providers and the full
implementation of the Fund's new master/feeder investment structure. During this
year, we have enjoyed explosive growth of new assets and investors to record
levels.

As many of you know, the Fund developed a master/feeder investment structure to
permit the Fund to expand its distribution channels to new markets and
shareholders, while permitting us to combine investment assets into our master
portfolios. Through this development, the Fund now offers six investment series,
each of which has received a AAA rating. As a result, the total assets of the
Fund have grown to a record high, as of October 31, 1999, of $893 million; and,
the number of shareholders has reached a new high of 335 shareholders. 2000 will
present a significant challenge if we hope to surpass the accomplishments of
1999, but I am confident that the Fund's service agents, Cadre Financial
Services, Inc. and Cadre Securities, Inc. stand ready to meet this challenge.

We will strive hard to exceed our 1999 accomplishments. For 2000, Cadre will
remain focused on the Fund's guiding principles of safety, liquidity and yield,
while continuing two major Fund initiatives -Technology and Education.

As we move into the new millennium, we are all faced with increasing demands and
decreasing resources. We all face the charge "Do more with less". Therefore, we
will increase our focus on one of the most valuable benefits of the Fund - Time.
Through the greater use of technology, we expect that the Fund will yield
greater TIME savings for you and your staff. Technology gives us the ability to
provide you with immediate access to your investments, online, permitting faster
processing time and the ability to conduct business on your time. Cadre has
invested great resources in the Fund's online reporting system, Compass, and
will do even more in 2000. During this coming year, Compass will be further
developed to provide enhanced reporting and transaction capability. Through
Compass, the Fund will continue to benefit its shareholders by reducing the time
spent managing your liquid assets.

Finally, important to us all, is the role of education. In the ever-changing
landscape of investments, it is very demanding to stay abreast of the latest
developments. The investment world is growing in complexity and the demands of
our positions are becoming increasingly challenging. For 2000, Cadre will focus
on providing value-added education in the many areas affecting your role as a
financial officer. Cadre intends to provide valuable investment and technology
seminars designed to help each of us better understand prudent investing and
effective cash management.

These initiatives will be as rewarding as they are difficult, but with your
continued support of the Fund, we are certain they will be accomplished. We look
forward to the millennium ahead.

Sincerely,

William T. Sullivan, Jr.
Chairman

CADRE LIQUID ASSET FUND - U.S. GOVERNMENT SERIES
ECONOMIC OVERVIEW
- --------------------------------------------------------------------------------

In September 1998, the failure of Long Term Capital Management, a large hedge
fund, caused global financial panic, which resulted in a global flight to
quality in the U.S. Treasury market. This flight to quality caused the yield on
the 30-Year Treasury Bond to decline below 4.75%, its lowest level in history.
The Federal Reserve responded by aggressively lowering the overnight bank rate
by 75 basis points. In a period of six weeks, the Fed lowered the Fed Funds
target interest rate, in a series of three 25 basis point moves (from 5.50% to
4.75%), which included a rare inter-meeting move in October of 1998. The decline
in interest rates was a result of the view that the domestic economy would slow
dramatically. However, global financial markets stabilized and the domestic
economy continued to show resilience.

During the period, Gross Domestic Product (GDP) grew at an annualized rate of
4.3% and in the third quarter GDP was up an impressive 5.5%. The consumer has
been the catalyst for this strong economy. The consumer has benefited from a
tight labor market as evidenced by an unemployment rate of 4.1% combined with
the wealth effect, a result of the impressive gains in the stock market. In
fact, in the first quarter of 1999, consumer spending, which accounts for two
thirds of economic activity posted its largest gain in eleven years.

This economic strength combined with a lower rate of unemployment, concerned Fed
officials enough to begin raising the Fed Funds target interest rate. In fact,
beginning on June 30th of 1999, the Fed embarked on a series of three 25 basis
point rate increases, with the most recent move occurring on November 16th. This
last move completely reversed all the monetary stimulus provided by the Fed in
the fourth quarter of 1998.

Although the economy continues to grow at a brisk pace and the Fed has responded
by reversing all of the reductions of 1998, inflation still remains absent. The
GDP price deflator, a measure of price increases followed by many investors,
rose at a 1.1% pace in the third quarter, down from the 1.4% rate of the
previous quarter. This data mirrors other inflationary measures. The Producer
Price Index (PPI) decreased .1% in October and excluding the volatile food and
energy components, the core PPI increased .3%. Through October, core PPI has
risen at a .9% annual rate, down from a 1.6% rate during the first ten months of
last year. Prices also remain well behaved at the consumer level. The Consumer
Price Index (CPI) increased .2% in October and the core CPI increased .2%.
Through October, core CPI has risen at a 1.9% annual rate, down from a 2.0% rate
during the first ten months of last year

Despite the unemployment rate being at its lowest level since 1970, wages remain
well under control. The employment cost index (ECI) increased .9% in the third
quarter and benefit costs rose .8%. For the twelve months ended September 30th
the ECI rose 3.1%, down from a 3.7% increase for the 12 month period ended
September 30th 1998.

Worker productivity has played a large role in the economy's ability to maintain
a low unemployment rate with little signs of inflation. In the third quarter,
worker productivity increased at a 4.2% annual rate, which was the largest gain
since the first quarter of 1998.

In the statement that accompanied the November rate increase, the Fed stated
that "the pool of available workers willing to take jobs has been drawn down
further in recent months, a trend that must eventually be contained if
inflationary imbalances are to remain in check." Therefore, we believe that
continued tightening of the labor market or signs of inflation could force
another Fed rate increase by the first quarter of 2000.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

To the Shareholders and Board of Trustees of
Cadre Institutional Investors Trust
Cadre Liquid Asset Fund - U.S. Government Series:

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - Cadre Institutional Investors Trust - Cadre
Liquid Asset Fund - U.S. Government Series (the "Fund"), as of October 31, 1999,
and the related statements of operations for the year then ended, the statements
of changes in net assets for each of the years in the two year period then
ended, and the financial highlights for each of the years in the four year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
October 31, 1999, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Cadre
Institutional Investors Trust - Cadre Liquid Asset Fund - U.S. Government Series
as of October 31, 1999, the results of its operations for the year then ended,
the changes in its net assets for the years in the two year period then ended,
and the financial highlights for each year in the four year period then ended,
in conformity with generally accepted accounting principles.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE LIQUID ASSET FUND - U.S. GOVERNMENT SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April, 1996 as a Delaware business trust
and is registered as an open-end management investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"). The Trust is
comprised of ten series as follows: Cadre Liquid Asset Fund - U.S. Government
Series, Cadre Liquid Asset Fund - Money Market Series, Cadre Affinity Fund -
U.S. Government Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve
Fund - U.S. Government Series, Cadre Reserve Fund - Money Market Series, Cadre
SweepCash Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market
Series , U.S. Government Money Market Portfolio and Money Market Portfolio.
Previously the Trust offered shares of Ambac U.S. Treasury Money Market Fund,
which ceased operations on June 30, 1997. The accompanying financial statements
and financial highlights are those of Cadre Liquid Asset Fund - U.S. Government
Series (the "Fund") (formerly known as Cadre Institutional Investors Trust
Liquid Asset Fund and U.S. Government Money Market Fund). The Fund commenced
investment operations on April 24, 1996.

At a meeting of the Fund's Board of Trustees (the "Trustees") held on June 17,
1998, the Trustees approved an amendment to the investment policy of the Fund to
permit the Fund to pursue its investment objective by investing all of its
investable assets in shares of the U.S. Government Money Market Portfolio (the
"Portfolio"). The Portfolio is a series of the Trust that has substantially the
same investment objective, policies and restrictions as the Fund. The Trustees
also approved certain amendments to the investment restrictions of the Fund and
a new investment advisory agreement with the investment adviser, in order to
permit implementation of this new policy. These amendments were subsequently
approved by the shareholders of the Fund at a meeting held on October 30, 1998.

On December 21, 1998, the Fund transferred all of its securities to the
Portfolio in exchange for interests in the Portfolio. This transfer of
securities was not a taxable event. Upon transfer of these securities, the Fund
began investing all of its investable assets in the Portfolio.

The value of the Fund's investment in the Portfolio, as reflected in the
Statement of Assets and Liabilities, reflects the Fund's proportionate interest
in the net assets of the Portfolio (24.4% at October 31, 1999). The Portfolio
has the same investment objectives as the Fund and the performance of the Fund
is directly affected by the performance of the Portfolio. The financial
statements of the Portfolio, including the Schedule of Investments, are included
elsewhere in this report and should be read in conjunction with the Fund's
financial statements.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

VALUATION OF SECURITIES
Valuation of securities by the Portfolio is discussed in Note 2 of the
Portfolio's Notes to Financial Statements, which are included elsewhere in this
report.

INVESTMENT INCOME
The Fund records its proportionate share of net investment income and realized
gains and losses each day. All of the net investment income and realized gain
and loss of the Portfolio is allocated on a pro-rata basis among the Fund and
the other investors in the Portfolio at the time of such determination.

DIVIDENDS TO SHAREHOLDERS
Substantially all of the Fund's net investment income and net realized capital
gains, if any, are declared as dividends daily and paid monthly. Net short-term
capital gains, if any, will be distributed in accordance with the requirements
of the Internal Revenue Code of 1986, as amended (the "Code"), and may be
reflected in the Fund's daily dividend rate. Substantially all of the realized
net long-term capital gains, if any, are declared and paid annually, except that
an additional capital gains distribution may be made in a given year to the
extent necessary to avoid the imposition of federal excise tax on the Fund.

Income dividends and capital gain distributions are determined in accordance
with income tax regulations, which may differ from generally accepted accounting
principles.

FEDERAL INCOME TAXES
The Fund is treated as a separate entity for federal income tax purposes and
intends to qualify each year as a "regulated investment company" under
Subchapter M of the Code and to make distributions of substantially all of its
income, including net realized capital gains, if any, to relieve it from
substantially all Federal and excise taxes. Therefore, no Federal tax provision
is required.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.

NOTE 3 - TRANSACTIONS WITH AFFILIATES

Prior to December 21, 1998, the Fund did not invest all of its investable assets
in the Portfolio. Rather, the Trust, on behalf of the Fund, had entered into an
Investment Advisory Agreement with Cadre Financial Services, Inc. ("Cadre"), a
wholly-owned subsidiary of Ambac Financial Group, Inc., whereby Cadre provided
investment advisory services to the Fund. For its services, Cadre was paid an
annual fee of 0.15% of the Fund's average daily net assets. This agreement was
terminated on December 21, 1998.

The Trust, on behalf of the Fund, has entered into an Administration Agreement
with Cadre, under which Cadre is responsible for certain aspects of the
administration and operation of the Fund. For its services, Cadre is paid an
annual fee of 0.19% of the Fund's first $250 million average daily net assets,
0.165% of the Fund's next $750 million average daily net assets and 0.14% of the
Fund's average daily net assets in excess of $1 billion. Prior to December 21,
1998, Cadre was entitled to administration fees of 0.10% of the Fund's first
$500 million average daily net assets, 0.075% of the Fund's next $500 million
average daily net assets and 0.05% of the Fund's average daily net assets in
excess of $1 billion.

The Trust, on behalf of the Fund, has entered into a Transfer Agent Agreement
with Cadre, under which Cadre is responsible for providing shareholder
recordkeeping services to the Fund. For its services, Cadre is paid an annual
fee of 0.05% of the Fund's first $250 million average daily net assets, 0.04% of
the Fund's next $750 million average daily net assets and 0.03% of the Fund's
average daily net assets in excess of $1 billion. Prior to December 21, 1998,
Cadre was entitled to transfer agent fees of 0.05% of the Fund's average daily
net assets.

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive distributor of the Trust's shares.

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.


NOTE 4 - WAIVER OF FEES AND REIMBURSEMENT OF EXPENSES

Cadre has voluntarily agreed to waive a portion of its fees and to reimburse the
Fund for certain expenses to the extent the total operating expenses of the Fund
exceed 0.45% (annualized) of the Funds average daily net

assets. During the year ended October 31, 1999, Cadre waived fees of $24,064 and
reimbursed expenses of $36,348 so that the Fund could meet this expense
limitation.

The Fund has adopted an Excess Expense Reimbursement Plan (the "Plan") pursuant
to which the Fund has agreed to reimburse Cadre for any waived fees or
reimbursed expenses to the extent the Fund's total operating expenses are less
than the expense limitation of 0.45% (annualized) of the Fund's average daily
net assets. The Plan which has a term of three years, terminates on March 16,
2002. During the year ended October 31, 1999, the Fund did not reimburse Cadre
for any fees waived or expenses reimbursed pursuant to the terms of the Plan.

                          ----------------------------

To the Shareholders and Board of Trustees of
Cadre Institutional Investors Trust
U.S. Government Money Market Portfolio

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - U.S. Government Money Market Portfolio (the
"Portfolio"), including the schedule of investments, as of October 31, 1999, and
the related statements of operations and changes in net assets for the period
December 21, 1998 (commencement of operations) through October 31, 1999. These
financial statements are the responsibility of the Portfolio's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cadre Institutional Investors
Trust - U.S. Government Money Market Portfolio as of October 31, 1999, the
results of its operations and the changes in its net assets for the period
December 21, 1998 (commencement of operations) through October 31, 1999, in
conformity with generally accepted accounting principles.

CADRE INSTITUTIONAL INVESTORS TRUST
U.S. GOVERNMENT MONEY MARKET PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April, 1996 as a Delaware business trust
and is registered as an open-end management investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"). The Trust is
comprised of ten series as follows: Cadre Liquid Asset Fund - U.S. Government
Series, Cadre Liquid Asset Fund - Money Market Series, Cadre Affinity Fund -
U.S. Government Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve
Fund - U.S. Government Series, Cadre Reserve Fund - Money Market Series, Cadre
SweepCash Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market
Series, U.S. Government Money Market Portfolio and Money Market Portfolio.
Previously the Trust offered the Ambac U.S. Treasury Money Market Fund, which
ceased operations on June 30, 1997. The accompanying financial statements and
financial highlights are those of the U.S. Government Money Market Portfolio
(the "Portfolio"). The Portfolio commenced investment operations on December 21,
1998 upon a tax free transfer of securities from the Cadre Liquid Asset Fund -
U.S. Government Series.


NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements.

VALUATION OF SECURITIES
Investments are valued at amortized cost, which approximates market value. The
amortized cost method of valuation values a security at its cost on the date of
purchase and thereafter assumes a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of the instruments.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME
Securities transactions are recorded on a trade date basis. Interest income,
which includes the amortization of discounts and premiums, if any, is recorded
on an accrual basis. Net realized gains or losses on sales of securities are
determined by the identified cost method.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


REPURCHASE AGREEMENTS
The Portfolio may engage in repurchase agreement transactions with institutions
that the Trust's adviser has determined are creditworthy pursuant to guidelines
established by the Trust's Board of Trustees. The Portfolio's custodian or
designated subcustodians, as the case may be under tri-party repurchase
agreements, takes possession of the collateral pledged for investments in
repurchase agreements on behalf of the Portfolio. It is the policy of the
Portfolio to value the underlying collateral daily on a mark-to-market basis to
determine that the value, including accrued interest, is at least equal to the
repurchase price plus accrued interest. In the event of default of the
obligation to repurchase, the Portfolio has the right to liquidate the
collateral and apply the proceeds in satisfaction of the obligation. Under
certain circumstances, in the event of default or bankruptcy by the other party
to the agreement, realization and/or retention of the collateral or proceeds may
be subject to legal proceedings.

FEDERAL INCOME TAXES
The Portfolio intends to be treated as a partnership for federal income tax
purposes. As such, each investor in the Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that the
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended. The cost of securities is
substantially the same for book and tax purposes.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.


NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Portfolio, has entered into an Investment Advisory
Agreement with Cadre Financial Services, Inc. ("Cadre"), a wholly-owned
subsidiary of Ambac Financial Group, Inc., whereby Cadre provides investment
advisory services and administrative services to the Portfolio. For its
services, Cadre is paid an annual fee of 0.06% of the Fund's average daily net
assets

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive placement agent of the Portfolio's
shares.

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.

CIIT CHAIRMAN'S ANNUAL REPORT LETTER
- --------------------------------------------------------------------------------

Dear Shareholders,

As 1999 comes to a close and we stand poised for the new millenium, I cannot
help but reflect on what a year this has been for the Cadre Institutional
Investors Trust (the "Fund"). Since the Fund's inception in 1995, there has not
been such a robust year of development. This year saw the successful
implementation of Y2K readiness projects by our service providers and the full
implementation of the Fund's new master/feeder investment structure. During this
year, we have enjoyed explosive growth of new assets and investors to record
levels.

As many of you know, the Fund developed a master/feeder investment structure to
permit the Fund to expand its distribution channels to new markets and
shareholders, while permitting us to combine investment assets into our master
portfolios. Through this development, the Fund now offers six investment series,
each of which has received a AAA rating. As a result, the total assets of the
Fund have grown to a record high, as of October 31, 1999, of $893 million; and,
the number of shareholders has reached a new high of 335 shareholders. 2000 will
present a significant challenge if we hope to surpass the accomplishments of
1999, but I am confident that the Fund's service agents, Cadre Financial
Services, Inc. and Cadre Securities, Inc. stand ready to meet this challenge.

We will strive hard to exceed our 1999 accomplishments. For 2000, Cadre will
remain focused on the Fund's guiding principles of safety, liquidity and yield,
while continuing two major Fund initiatives -Technology and Education.

As we move into the new millennium, we are all faced with increasing demands and
decreasing resources. We all face the charge "Do more with less". Therefore, we
will increase our focus on one of the most valuable benefits of the Fund - Time.
Through the greater use of technology, we expect that the Fund will yield
greater TIME savings for you and your staff. Technology gives us the ability to
provide you with immediate access to your investments, online, permitting faster
processing time and the ability to conduct business on your time. Cadre has
invested great resources in the Fund's online reporting system, Compass, and
will do even more in 2000. During this coming year, Compass will be further
developed to provide enhanced reporting and transaction capability. Through
Compass, the Fund will continue to benefit its shareholders by reducing the time
spent managing your liquid assets.

Finally, important to us all, is the role of education. In the ever-changing
landscape of investments, it is very demanding to stay abreast of the latest
developments. The investment world is growing in complexity and the demands of
our positions are becoming increasingly challenging. For 2000, Cadre will focus
on providing value-added education in the many areas affecting your role as a
financial officer. Cadre intends to provide valuable investment and technology
seminars designed to help each of us better understand prudent investing and
effective cash management.

These initiatives will be as rewarding as they are difficult, but with your
continued support of the Fund, we are certain they will be accomplished. We look
forward to the millennium ahead.

Sincerely,

William T. Sullivan, Jr.
Chairman

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE AFFINITY FUND - U.S. GOVERNMENT SERIES
ECONOMIC OVERVIEW
- --------------------------------------------------------------------------------

In September 1998, the failure of Long Term Capital Management, a large hedge
fund, caused global financial panic, which resulted in a global flight to
quality in the U.S. Treasury market. This flight to quality caused the yield on
the 30-Year Treasury Bond to decline below 4.75%, its lowest level in history.
The Federal Reserve responded by aggressively lowering the overnight bank rate
by 75 basis points. In a period of six weeks, the Fed lowered the Fed Funds
target interest rate, in a series of three 25 basis point moves (from 5.50% to
4.75%), which included a rare inter-meeting move in October of 1998. The decline
in interest rates was a result of the view that the domestic economy would slow
dramatically. However, global financial markets stabilized and the domestic
economy continued to show resilience.

During the period, Gross Domestic Product (GDP) grew at an annualized rate of
4.3% and in the third quarter GDP was up an impressive 5.5%. The consumer has
been the catalyst for this strong economy. The consumer has benefited from a
tight labor market as evidenced by an unemployment rate of 4.1% combined with
the wealth effect, a result of the impressive gains in the stock market. In
fact, in the first quarter of 1999, consumer spending, which accounts for two
thirds of economic activity posted its largest gain in eleven years.

This economic strength combined with a lower rate of unemployment, concerned Fed
officials enough to begin raising the Fed Funds target interest rate. In fact,
beginning on June 30th of 1999, the Fed embarked on a series of three 25 basis
point rate increases, with the most recent move occurring on November 16th. This
last move completely reversed all the monetary stimulus provided by the Fed in
the fourth quarter of 1998.

Although the economy continues to grow at a brisk pace and the Fed has responded
by reversing all of the reductions of 1998, inflation still remains absent. The
GDP price deflator, a measure of price increases followed by many investors,
rose at a 1.1% pace in the third quarter, down from the 1.4% rate of the
previous quarter. This data mirrors other inflationary measures. The Producer
Price Index (PPI) decreased .1% in October and excluding the volatile food and
energy components, the core PPI increased .3%. Through October, core PPI has
risen at a .9% annual rate, down from a 1.6% rate during the first ten months of
last year. Prices also remain well behaved at the consumer level. The Consumer
Price Index (CPI) increased .2% in October and the core CPI increased .2%.
Through October, core CPI has risen at a 1.9% annual rate, down from a 2.0% rate
during the first ten months of last year

Despite the unemployment rate being at its lowest level since 1970, wages remain
well under control. The employment cost index (ECI) increased .9% in the third
quarter and benefit costs rose .8%. For the twelve months ended September 30th
the ECI rose 3.1%, down from a 3.7% increase for the 12 month period ended
September 30th 1998.

Worker productivity has played a large role in the economy's ability to maintain
a low unemployment rate with little signs of inflation. In the third quarter,
worker productivity increased at a 4.2% annual rate, which was the largest gain
since the first quarter of 1998.

In the statement that accompanied the November rate increase, the Fed stated
that "the pool of available workers willing to take jobs has been drawn down
further in recent months, a trend that must eventually be contained if
inflationary imbalances are to remain in check." Therefore, we believe that
continued tightening of the labor market or signs of inflation could force
another Fed rate increase by the first quarter of 2000.

To the Shareholders and Board of Trustees of

Cadre Affinity Fund - U.S. Government Series:

We have audited the accompanying statement of assets and liabilities of Cadre

statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Cadre
Institutional Investors Trust - Cadre Affinity Fund - U.S. Government Series as

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE AFFINITY FUND - U.S. GOVERNMENT SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April, 1996 as a Delaware business trust
and is registered as an open-end management investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"). The Trust is
comprised of ten series as follows: Cadre Liquid Asset Fund - U.S. Government
Series, Cadre Liquid Asset Fund - Money Market Series, Cadre Affinity Fund -
U.S. Government Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve
Fund - U.S. Government Series, Cadre Reserve Fund - Money Market Series, Cadre
SweepCash Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market
Series, U.S. Government Money Market Portfolio and Money Market Portfolio.
Previously the Trust offered the Ambac U.S. Treasury Money Market Fund, which
ceased operations on June 30, 1997. The accompanying financial statements and
financial highlights are those of Cadre Affinity Fund - U.S. Government Series
(the "Fund"). The Fund commenced investment operations on May 3, 1999.

The Fund invests all of its investable assets in the U.S. Government Money
Market Portfolio ("the Portfolio"). The Portfolio has the same investment
objectives as the Fund.

The value of the Fund's investment in the Portfolio, as reflected in the
Statement of Assets and Liabilities, reflects the Fund's proportionate interest
in the net assets of the Portfolio (13.5% at October 31, 1999). The Portfolio
has the same investment objective as the Fund and the performance of the Fund is
directly affected by the performance of the Portfolio. The financial statements
of the Portfolio, including the Schedule of Investments, are included elsewhere
in this report and should be read in conjunction with the Fund's financial
statements.


NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

VALUATION OF SECURITIES
Valuation of securities by the Portfolio is discussed in Note 2 of the
Portfolio's Notes to Financial Statements, which are included elsewhere in this
report.

INVESTMENT INCOME
The Fund records its proportionate share of net investment income and realized
gains and losses each day. All of the net investment income and realized gain
and loss of the Portfolio is allocated on a pro-rata basis among the Fund and
the other investors in the Portfolio at the time of such determination.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE AFFINITY FUND - U.S. GOVERNMENT SERIES
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


DIVIDENDS TO SHAREHOLDERS
Substantially all of the Fund's net investment income and net realized capital
gains, if any, are declared as dividends daily and paid monthly. Net short-term
capital gains, if any, will be distributed in accordance with the requirements
of the Internal Revenue Code of 1986, as amended (the "Code"), and may be
reflected in the Fund's daily dividend rate. Substantially all of the realized
net long-term capital gains, if any, are declared and paid annually, except that
an additional capital gains distribution may be made in a given year to the
extent necessary to avoid the imposition of federal excise tax on the Fund.
Income dividends and capital gain distributions are determined in accordance
with income tax regulations, which may differ from generally accepted accounting
principles.

FEDERAL INCOME TAXES
The Fund is treated as a separate entity for federal income tax purposes and
intends to qualify each year as a "regulated investment company" under
Subchapter M of the Code and to make distributions of substantially all of its
income, including net realized capital gains, if any, to relieve it from
substantially all Federal and excise taxes. Therefore, no Federal tax provision
is required.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.


NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Fund, has entered into an Administration Agreement
with Cadre Financial Services, Inc. ("Cadre"), a wholly-owned subsidiary of the
Ambac Financial Group, Inc., under which Cadre is responsible for certain
aspects of the administration and operation of the Fund. For its services, Cadre
is paid an annual fee of 0.10% of the Fund's first $250 million average daily
net assets, 0.075% of the Fund's next $750 million average daily net assets and
0.05% of the Fund's average daily net assets in excess of $1 billion.

The Trust, on behalf of the Fund, has entered into a Transfer Agent Agreement
with Cadre, under which Cadre is responsible for providing shareholder
recordkeeping services to the Fund. For its services, Cadre is paid an annual
fee of 0.05% of the Fund's first $250 million average daily net assets, 0.04% of
the Fund's next $750 million average daily net assets and 0.03% of the Fund's
average daily net assets in excess of $1 billion.

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive distributor of the Trust's shares.

- --------------------------------------------------------------------------------

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend.

Members of the Audit Committee receive an attendance fee of $750 for each Audit
Committee meeting they attend. The Chairman of the Audit Committee receives an
additional $1,000 annual fee. Officers of the Trust receive no compensation from
the Trust.


NOTE 4 - WAIVER OF FEES AND REIMBURSEMENT OF EXPENSES

Cadre has voluntarily agreed to waive a portion of its fees and to reimburse the
Fund for certain expenses to the extent the total operating expenses of the Fund
exceed 0.55% (annualized) of the Funds average daily net assets. During the
period May 3, 1999 (commencement of operations) through October 31, 1999, Cadre
waived fees of $33,664 and reimbursed expenses of $39,150 so that the Fund could
meet this expense limitation.

The Fund has adopted an Excess Expense Reimbursement Plan (the "Plan") pursuant
to which the Fund has agreed to reimburse Cadre for any waived fees or
reimbursed expenses to the extent the Fund's total operating expenses go below
the expense limitation of 0.55% (annualized) of the Fund's average daily net
assets. The Plan has a term of three years from its adoption date of March 16,
2002. During the period May 3, 1999 (commencement of operations) through October
31, 1999, the Fund did not reimburse Cadre for any fees waived or expenses
reimbursed pursuant to the terms of the plan.

                          ----------------------------

To the Shareholders and Board of Trustees of
Cadre Institutional Investors Trust
U.S. Government Money Market Portfolio

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - U.S. Government Money Market Portfolio (the
"Portfolio"), including the schedule of investments, as of October 31, 1999, and
the related statements of operations and changes in net assets for the period
December 21, 1998 (commencement of operations) through October 31, 1999. These
financial statements are the responsibility of the Portfolio's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cadre Institutional Investors
Trust - U.S. Government Money Market Portfolio as of October 31, 1999, the
results of its operations and the changes in its net assets for the period
December 21, 1998 (commencement of operations) through October 31, 1999, in
conformity with generally accepted accounting principles.

CADRE INSTITUTIONAL INVESTORS TRUST
U.S. GOVERNMENT MONEY MARKET PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April, 1996 as a Delaware business trust
and is registered as an open-end management investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"). The Trust is
comprised of ten series as follows: Cadre Liquid Asset Fund - U.S. Government
Series, Cadre Liquid Asset Fund - Money Market Series, Cadre Affinity Fund -
U.S. Government Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve
Fund - U.S. Government Series, Cadre Reserve Fund - Money Market Series, Cadre
SweepCash Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market
Series, U.S. Government Money Market Portfolio and Money Market Portfolio.
Previously the Trust offered the Ambac U.S. Treasury Money Market Fund, which
ceased operations on June 30, 1997. The accompanying financial statements and
financial highlights are those of the U.S. Government Money Market Portfolio
(the "Portfolio"). The Portfolio commenced investment operations on December 21,
1998 upon a tax free transfer of securities from the Cadre Liquid Asset Fund -
U.S. Government Series.


NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements.

VALUATION OF SECURITIES
Investments are valued at amortized cost, which approximates market value. The
amortized cost method of valuation values a security at its cost on the date of
purchase and thereafter assumes a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of the instruments.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME
Securities transactions are recorded on a trade date basis. Interest income,
which includes the amortization of discounts and premiums, if any, is recorded
on an accrual basis. Net realized gains or losses on sales of securities are
determined by the identified cost method.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


REPURCHASE AGREEMENTS
The Portfolio may engage in repurchase agreement transactions with institutions
that the Trust's adviser has determined are creditworthy pursuant to guidelines
established by the Trust's Board of Trustees. The Portfolio's custodian or
designated subcustodians, as the case may be under tri-party repurchase
agreements, takes possession of the collateral pledged for investments in
repurchase agreements on behalf of the Portfolio. It is the policy of the
Portfolio to value the underlying collateral daily on a mark-to-market basis to
determine that the value, including accrued interest, is at least equal to the
repurchase price plus accrued interest. In the event of default of the
obligation to repurchase, the Portfolio has the right to liquidate the
collateral and apply the proceeds in satisfaction of the obligation. Under
certain circumstances, in the event of default or bankruptcy by the other party
to the agreement, realization and/or retention of the collateral or proceeds may
be subject to legal proceedings.

FEDERAL INCOME TAXES
The Portfolio intends to be treated as a partnership for federal income tax
purposes. As such, each investor in the Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that the
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended. The cost of securities is
substantially the same for book and tax purposes.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.


NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Portfolio, has entered into an Investment Advisory
Agreement with Cadre Financial Services, Inc. ("Cadre"), a wholly-owned
subsidiary of Ambac Financial Group, Inc., whereby Cadre provides investment
advisory services and administrative services to the Portfolio. For its
services, Cadre is paid an annual fee of 0.06% of the Fund's average daily net
assets

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive placement agent of the Portfolio's
shares.

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE RESERVE FUND - U.S. GOVERNMENT SERIES
CIIT CHAIRMAN'S ANNUAL REPORT LETTER
- --------------------------------------------------------------------------------

Dear Shareholders,

As 1999 comes to a close and we stand poised for the new millenium, I cannot
help but reflect on what a year this has been for the Cadre Institutional
Investors Trust (the "Fund"). Since the Fund's inception in 1995, there has not
been such a robust year of development. This year saw the successful
implementation of Y2K readiness projects by our service providers and the full
implementation of the Fund's new master/feeder investment structure. During this
year, we have enjoyed explosive growth of new assets and investors to record
levels.

As many of you know, the Fund developed a master/feeder investment structure to
permit the Fund to expand its distribution channels to new markets and
shareholders, while permitting us to combine investment assets into our master
portfolios. Through this development, the Fund now offers six investment series,
each of which has received a AAA rating. As a result, the total assets of the
Fund have grown to a record high, as of October 31, 1999, of $893 million; and,
the number of shareholders has reached a new high of 335 shareholders. 2000 will
present a significant challenge if we hope to surpass the accomplishments of
1999, but I am confident that the Fund's service agents, Cadre Financial
Services, Inc. and Cadre Securities, Inc. stand ready to meet this challenge.

We will strive hard to exceed our 1999 accomplishments. For 2000, Cadre will
remain focused on the Fund's guiding principles of safety, liquidity and yield,
while continuing two major Fund initiatives -Technology and Education.

As we move into the new millennium, we are all faced with increasing demands and
decreasing resources. We all face the charge "Do more with less". Therefore, we
will increase our focus on one of the most valuable benefits of the Fund - Time.
Through the greater use of technology, we expect that the Fund will yield
greater TIME savings for you and your staff. Technology gives us the ability to
provide you with immediate access to your investments, online, permitting faster
processing time and the ability to conduct business on your time. Cadre has
invested great resources in the Fund's online reporting system, Compass, and
will do even more in 2000. During this coming year, Compass will be further
developed to provide enhanced reporting and transaction capability. Through
Compass, the Fund will continue to benefit its shareholders by reducing the time
spent managing your liquid assets.

Finally, important to us all, is the role of education. In the ever-changing
landscape of investments, it is very demanding to stay abreast of the latest
developments. The investment world is growing in complexity and the demands of
our positions are becoming increasingly challenging. For 2000, Cadre will focus
on providing value-added education in the many areas affecting your role as a
financial officer. Cadre intends to provide valuable investment and technology
seminars designed to help each of us better understand prudent investing and
effective cash management.

These initiatives will be as rewarding as they are difficult, but with your
continued support of the Fund, we are certain they will be accomplished. We look
forward to the millennium ahead.

Sincerely,

William T. Sullivan, Jr.
Chairman

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE RESERVE FUND - U.S. GOVERNMENT SERIES
ECONOMIC OVERVIEW
- --------------------------------------------------------------------------------

In September 1998, the failure of Long Term Capital Management, a large hedge
fund, caused global financial panic, which resulted in a global flight to
quality in the U.S. Treasury market. This flight to quality caused the yield on
the 30-Year Treasury Bond to decline below 4.75%, its lowest level in history.
The Federal Reserve responded by aggressively lowering the overnight bank rate
by 75 basis points. In a period of six weeks, the Fed lowered the Fed Funds
target interest rate, in a series of three 25 basis point moves (from 5.50% to
4.75%), which included a rare inter-meeting move in October of 1998. The decline
in interest rates was a result of the view that the domestic economy would slow
dramatically. However, global financial markets stabilized and the domestic
economy continued to show resilience.

During the period, Gross Domestic Product (GDP) grew at an annualized rate of
4.3% and in the third quarter GDP was up an impressive 5.5%. The consumer has
been the catalyst for this strong economy. The consumer has benefited from a
tight labor market as evidenced by an unemployment rate of 4.1% combined with
the wealth effect, a result of the impressive gains in the stock market. In
fact, in the first quarter of 1999, consumer spending, which accounts for two
thirds of economic activity posted its largest gain in eleven years.

This economic strength combined with a lower rate of unemployment, concerned Fed
officials enough to begin raising the Fed Funds target interest rate. In fact,
beginning on June 30th of 1999, the Fed embarked on a series of three 25 basis
point rate increases, with the most recent move occurring on November 16th. This
last move completely reversed all the monetary stimulus provided by the Fed in
the fourth quarter of 1998.

Although the economy continues to grow at a brisk pace and the Fed has responded
by reversing all of the reductions of 1998, inflation still remains absent. The
GDP price deflator, a measure of price increases followed by many investors,
rose at a 1.1% pace in the third quarter, down from the 1.4% rate of the
previous quarter. This data mirrors other inflationary measures. The Producer
Price Index (PPI) decreased .1% in October and excluding the volatile food and
energy components, the core PPI increased .3%. Through October, core PPI has
risen at a .9% annual rate, down from a 1.6% rate during the first ten months of
last year. Prices also remain well behaved at the consumer level. The Consumer
Price Index (CPI) increased .2% in October and the core CPI increased .2%.
Through October, core CPI has risen at a 1.9% annual rate, down from a 2.0% rate
during the first ten months of last year

Despite the unemployment rate being at its lowest level since 1970, wages remain
well under control. The employment cost index (ECI) increased .9% in the third
quarter and benefit costs rose .8%. For the twelve months ended September 30th
the ECI rose 3.1%, down from a 3.7% increase for the 12 month period ended
September 30th 1998.

Worker productivity has played a large role in the economy's ability to maintain
a low unemployment rate with little signs of inflation. In the third quarter,
worker productivity increased at a 4.2% annual rate, which was the largest gain
since the first quarter of 1998.

In the statement that accompanied the November rate increase, the Fed stated
that "the pool of available workers willing to take jobs has been drawn down
further in recent months, a trend that must eventually be contained if
inflationary imbalances are to remain in check." Therefore, we believe that
continued tightening of the labor market or signs of inflation could force
another Fed rate increase by the first quarter of 2000.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

To the Shareholders and Board of Trustees of
Cadre Institutional Investors Trust
Cadre Reserve Fund - U.S. Government Series:

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - Cadre Reserve Fund - U.S. Government Series (the
"Fund"), as of October 31, 1999, and the related statements of operations,
changes in net assets and the financial highlights for the period January 5,
1999 (commencement of operations) through October 31, 1999. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Cadre
Institutional Investors Trust - Cadre Reserve Fund - U.S Government Series as of
October 31, 1999, the results of its operations, the changes in its net assets,
and the financial highlights for the period January 5, 1999 (commencement of
operations) through October 31, 1999, in conformity with generally accepted
accounting principles.

                                                 /s/ KPMG LLP
                                                 ------------

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE RESERVE FUND - U.S. GOVERNMENT SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April, 1996 as a Delaware business trust
and is registered as an open-end management investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"). The Trust is
comprised of ten series as follows: Cadre Liquid Asset Fund - U.S. Government
Series, Cadre Liquid Asset Fund - Money Market Series, Cadre Affinity Fund -
U.S. Government Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve
Fund - U.S. Government Series, Cadre Reserve Fund - Money Market Series, Cadre
SweepCash Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market
Series, U.S. Government Money Market Portfolio and Money Market Portfolio.
Previously the Trust offered the Ambac U.S. Treasury Money Market Fund, which
ceased operations on June 30, 1997. The accompanying financial statements and
financial highlights are those of Cadre Reserve Fund - U.S. Government Series
(the "Fund"). The Fund commenced investment operations on January 5, 1999.

The Fund invests all of its investable assets in the U.S. Government Money
Market Portfolio (the "Portfolio"). The Portfolio is a series of the trust that
has substantially the same investment objectives, policies and restrictions as
the Fund.

 The value of the Fund's investment in the Portfolio, as reflected in the
Statement of Assets and Liabilities, reflects the Fund's proportionate interest
in the net assets of the Portfolio (62.1% at October 31, 1999). The Portfolio
has the same investment objective as the Fund and the performance of the Fund is
directly affected by the performance of the Portfolio. The financial statements
of the Portfolio, including the Schedule of Investments, are included elsewhere
in this report and should be read in conjunction with the Fund's financial
statements.


NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

VALUATION OF SECURITIES
Valuation of securities by the Portfolio is discussed in Note 2 of the
Portfolio's Notes to Financial Statements, which are included elsewhere in this
report.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE RESERVE FUND - U.S. GOVERNMENT SERIES
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
OCTOBER 31, 1999
- --------------------------------------------------------------------------------

INVESTMENT INCOME
The Fund records its proportionate share of net investment income and realized
gains and losses each day. All of the net investment income and realized gain
and loss of the Portfolio is allocated on a pro-rata basis among the Fund and
the other investors in the Portfolio at the time of such determination.

DIVIDENDS TO SHAREHOLDERS
Substantially all of the Fund's net investment income and net realized capital
gains, if any, are declared as dividends daily and paid monthly. Net short-term
capital gains, if any, will be distributed in accordance with the requirements
of the Internal Revenue Code of 1986, as amended (the "Code"), and may be
reflected in the Fund's daily dividend rate. Substantially all of the realized
net long-term capital gains, if any, are declared and paid annually, except that
an additional capital gains distribution may be made in a given year to the
extent necessary to avoid the imposition of federal excise tax on the Fund.
Income dividends and capital gain distributions are determined in accordance
with income tax regulations, which may differ from generally accepted accounting
principles.

FEDERAL INCOME TAXES
The Fund is treated as a separate entity for federal income tax purposes and
intends to qualify each year as a "regulated investment company" under
Subchapter M of the Code and to make distributions of substantially all of its
income, including net realized capital gains, if any, to relieve it from
substantially all Federal and excise taxes. Therefore, no Federal tax provision
is required.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.


NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Fund, has entered into an Administration Agreement
with Cadre Financial Services, Inc. ("Cadre"), a wholly-owned subsidiary of
Ambac Financial Group, Inc., under which Cadre is responsible for certain
aspects of the administration and operation of the Fund. For its services, Cadre
is paid an annual fee of 0.10% of the Fund's first $250 million average daily
net assets, 0.075% of the Fund's next $750 million average daily net assets and
0.05% of the Fund's average daily net assets in excess of $1 billion.

The Trust, on behalf of the Fund, has entered into a Transfer Agent Agreement
with Cadre, under which Cadre is responsible for providing shareholder
recordkeeping services to the Fund. For its services, Cadre is paid an annual
fee of 0.05% of the Fund's first $250 million average daily net assets, 0.04% of
the Fund's next $750 million average daily net assets and 0.03% of the Fund's
average daily net assets in excess of $1 billion.

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive distributor of the Trust's shares.

- --------------------------------------------------------------------------------

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend.

Members of the Audit Committee receive an attendance fee of $750 for each Audit
Committee meeting they attend. The Chairman of the Audit Committee receives an
additional $1,000 annual fee. Officers of the Trust receive no compensation from
the Trust.


NOTE 4 - WAIVER OF FEES AND REIMBURSEMENT OF EXPENSES

Cadre has voluntarily agreed to waive a portion of its fees and to reimburse the
Fund for certain expenses to the extent the total operating expenses of the Fund
exceed 0.20% (annualized) of the Funds average daily net assets. During the
period January 5, 1999(commencement of operations) through October 31, 1999,
Cadre waived fees of $110,427 and reimbursed expenses of $106,236 so that the
Fund could meet this expense limitation.

The Fund has adopted an Excess Expense Reimbursement Plan (the "Plan") pursuant
to which the Fund has agreed to reimburse Cadre for any waived fees or
reimbursed expenses to the extent the Fund's total operating expenses go below
the expense limitation of 0.20% (annualized) of the Fund's average daily net
assets. The Plan has a term of three years from its adoption date of March 16,
2002. During the period January 5, 1999 (commencement of operations) through

                          ----------------------------

To the Shareholders and Board of Trustees of
Cadre Institutional Investors Trust
U.S. Government Money Market Portfolio

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - U.S. Government Money Market Portfolio (the
"Portfolio"), including the schedule of investments, as of October 31, 1999, and
the related statements of operations and changes in net assets for the period
December 21, 1998 (commencement of operations) through October 31, 1999. These
financial statements are the responsibility of the Portfolio's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cadre Institutional Investors
Trust - U.S. Government Money Market Portfolio as of October 31, 1999, the
results of its operations and the changes in its net assets for the period
December 21, 1998 (commencement of operations) through October 31, 1999, in
conformity with generally accepted accounting principles.

CADRE INSTITUTIONAL INVESTORS TRUST
U.S. GOVERNMENT MONEY MARKET PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April, 1996 as a Delaware business trust
and is registered as an open-end management investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"). The Trust is
comprised of ten series as follows: Cadre Liquid Asset Fund - U.S. Government
Series, Cadre Liquid Asset Fund - Money Market Series, Cadre Affinity Fund -
U.S. Government Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve
Fund - U.S. Government Series, Cadre Reserve Fund - Money Market Series, Cadre
SweepCash Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market
Series, U.S. Government Money Market Portfolio and Money Market Portfolio.
Previously the Trust offered the Ambac U.S. Treasury Money Market Fund, which
ceased operations on June 30, 1997. The accompanying financial statements and
financial highlights are those of the U.S. Government Money Market Portfolio
(the "Portfolio"). The Portfolio commenced investment operations on December 21,
1998 upon a tax free transfer of securities from the Cadre Liquid Asset Fund -
U.S. Government Series.


NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements.

VALUATION OF SECURITIES
Investments are valued at amortized cost, which approximates market value. The
amortized cost method of valuation values a security at its cost on the date of
purchase and thereafter assumes a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of the instruments.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME
Securities transactions are recorded on a trade date basis. Interest income,
which includes the amortization of discounts and premiums, if any, is recorded
on an accrual basis. Net realized gains or losses on sales of securities are
determined by the identified cost method.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
OCTOBER 31, 1999
- --------------------------------------------------------------------------------


REPURCHASE AGREEMENTS
The Portfolio may engage in repurchase agreement transactions with institutions
that the Trust's adviser has determined are creditworthy pursuant to guidelines
established by the Trust's Board of Trustees. The Portfolio's custodian or
designated subcustodians, as the case may be under tri-party repurchase
agreements, takes possession of the collateral pledged for investments in
repurchase agreements on behalf of the Portfolio. It is the policy of the
Portfolio to value the underlying collateral daily on a mark-to-market basis to
determine that the value, including accrued interest, is at least equal to the
repurchase price plus accrued interest. In the event of default of the
obligation to repurchase, the Portfolio has the right to liquidate the
collateral and apply the proceeds in satisfaction of the obligation. Under
certain circumstances, in the event of default or bankruptcy by the other party
to the agreement, realization and/or retention of the collateral or proceeds may
be subject to legal proceedings.

FEDERAL INCOME TAXES
The Portfolio intends to be treated as a partnership for federal income tax
purposes. As such, each investor in the Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that the
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended. The cost of securities is
substantially the same for book and tax purposes.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.


NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Portfolio, has entered into an Investment Advisory
Agreement with Cadre Financial Services, Inc. ("Cadre"), a wholly-owned
subsidiary of Ambac Financial Group, Inc., whereby Cadre provides investment
advisory services and administrative services to the Portfolio. For its
services, Cadre is paid an annual fee of 0.06% of the Fund's average daily net
assets

Cadre Securities, Inc. (the "Distributor"), a whollyo-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive placement agent of the Portfolio's
shares.

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE LIQUID ASSET FUND - MONEY MARKET SERIES
CIIT CHAIRMAN'S ANNUAL REPORT LETTER
- --------------------------------------------------------------------------------

Dear Shareholders,

As 1999 comes to a close and we stand poised for the new millenium, I cannot
help but reflect on what a year this has been for the Cadre Institutional
Investors Trust (the "Fund"). Since the Fund's inception in 1995, there has not
been such a robust year of development. This year saw the successful
implementation of Y2K readiness projects by our service providers and the full
implementation of the Fund's new master/feeder investment structure. During this
year, we have enjoyed explosive growth of new assets and investors to record
levels.

As many of you know, the Fund developed a master/feeder investment structure to
permit the Fund to expand its distribution channels to new markets and
shareholders, while permitting us to combine investment assets into our master
portfolios. Through this development, the Fund now offers six investment series,
each of which has received a AAA rating. As a result, the total assets of the
Fund have grown to a record high, as of October 31, 1999, of $893 million; and,
the number of shareholders has reached a new high of 335 shareholders. 2000 will
present a significant challenge if we hope to surpass the accomplishments of
1999, but I am confident that the Fund's service agents, Cadre Financial
Services, Inc. and Cadre Securities, Inc. stand ready to meet this challenge.

We will strive hard to exceed our 1999 accomplishments. For 2000, Cadre will
remain focused on the Fund's guiding principles of safety, liquidity and yield,
while continuing two major Fund initiatives -Technology and Education.

As we move into the new millennium, we are all faced with increasing demands and
decreasing resources. We all face the charge "Do more with less". Therefore, we
will increase our focus on one of the most valuable benefits of the Fund - Time.
Through the greater use of technology, we expect that the Fund will yield
greater TIME savings for you and your staff. Technology gives us the ability to
provide you with immediate access to your investments, online, permitting faster
processing time and the ability to conduct business on your time. Cadre has
invested great resources in the Fund's online reporting system, Compass, and
will do even more in 2000. During this coming year, Compass will be further
developed to provide enhanced reporting and transaction capability. Through
Compass, the Fund will continue to benefit its shareholders by reducing the time
spent managing your liquid assets.

Finally, important to us all, is the role of education. In the ever-changing
landscape of investments, it is very demanding to stay abreast of the latest
developments. The investment world is growing in complexity and the demands of
our positions are becoming increasingly challenging. For 2000, Cadre will focus
on providing value-added education in the many areas affecting your role as a
financial officer. Cadre intends to provide valuable investment and technology
seminars designed to help each of us better understand prudent investing and
effective cash management.

These initiatives will be as rewarding as they are difficult, but with your
continued support of the Fund, we are certain they will be accomplished. We look
forward to the millennium ahead.

Sincerely,

William T. Sullivan, Jr.
Chairman

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE LIQUID ASSET FUND - MONEY MARKET SERIES
ECONOMIC OVERVIEW
- --------------------------------------------------------------------------------

In September 1998, the failure of Long Term Capital Management, a large hedge
fund, caused global financial panic, which resulted in a global flight to
quality in the U.S. Treasury market. This flight to quality caused the yield on
the 30-Year Treasury Bond to decline below 4.75%, its lowest level in history.
The Federal Reserve responded by aggressively lowering the overnight bank rate
by 75 basis points. In a period of six weeks, the Fed lowered the Fed Funds
target interest rate, in a series of three 25 basis point moves (from 5.50% to
4.75%), which included a rare inter-meeting move in October of 1998. The decline
in interest rates was a result of the view that the domestic economy would slow
dramatically. However, global financial markets stabilized and the domestic
economy continued to show resilience.

During the period, Gross Domestic Product (GDP) grew at an annualized rate of
4.3% and in the third quarter GDP was up an impressive 5.5%. The consumer has
been the catalyst for this strong economy. The consumer has benefited from a
tight labor market as evidenced by an unemployment rate of 4.1% combined with
the wealth effect, a result of the impressive gains in the stock market. In
fact, in the first quarter of 1999, consumer spending, which accounts for two
thirds of economic activity posted its largest gain in eleven years.

This economic strength combined with a lower rate of unemployment, concerned Fed
officials enough to begin raising the Fed Funds target interest rate. In fact,
beginning on June 30th of 1999, the Fed embarked on a series of three 25 basis
point rate increases, with the most recent move occurring on November 16th. This
last move completely reversed all the monetary stimulus provided by the Fed in
the fourth quarter of 1998.

Although the economy continues to grow at a brisk pace and the Fed has responded
by reversing all of the reductions of 1998, inflation still remains absent. The
GDP price deflator, a measure of price increases followed by many investors,
rose at a 1.1% pace in the third quarter, down from the 1.4% rate of the
previous quarter. This data mirrors other inflationary measures. The Producer
Price Index (PPI) decreased .1% in October and excluding the volatile food and
energy components, the core PPI increased .3%. Through October, core PPI has
risen at a .9% annual rate, down from a 1.6% rate during the first ten months of
last year. Prices also remain well behaved at the consumer level. The Consumer
Price Index (CPI) increased .2% in October and the core CPI increased .2%.
Through October, core CPI has risen at a 1.9% annual rate, down from a 2.0% rate
during the first ten months of last year

Despite the unemployment rate being at its lowest level since 1970, wages remain
well under control. The employment cost index (ECI) increased .9% in the third
quarter and benefit costs rose .8%. For the twelve months ended September 30th
the ECI rose 3.1%, down from a 3.7% increase for the 12 month period ended
September 30th 1998.

Worker productivity has played a large role in the economy's ability to maintain
a low unemployment rate with little signs of inflation. In the third quarter,
worker productivity increased at a 4.2% annual rate, which was the largest gain
since the first quarter of 1998.

In the statement that accompanied the November rate increase, the Fed stated
that "the pool of available workers willing to take jobs has been drawn down
further in recent months, a trend that must eventually be contained if
inflationary imbalances are to remain in check." Therefore, we believe that
continued tightening of the labor market or signs of inflation could force
another Fed rate increase by the first quarter of 2000.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

To the Shareholders and Board of Trustees of Cadre Institutional Investors Trust
Cadre Liquid Asset Fund - Money Market Series:

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - Cadre Liquid Asset Fund - Money Market Series
(the "Fund"), as of October 31, 1999, and the related statements of operations,
changes in net assets and the financial highlights for the period May 3, 1999
(commencement of operations) through October 31, 1999. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Cadre
Institutional Investors Trust - Cadre Liquid Asset Fund - Money Market Series as
of October 31, 1999, the results of its operations, the changes in its net
assets, and the financial highlights for the period May 3, 1999 (commencement of

accounting principles.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE LIQUID ASSET FUND - MONEY MARKET SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------

NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April 1996 as a Delaware business trust and
is registered as an open-end management investment company under the Investment
Company Act of 1940, as amended (the "1940 Act"). The Trust is comprised of ten
series as follows: Cadre Liquid Asset Fund - U.S. Government Series, Cadre
Liquid Asset Fund - Money Market Series, Cadre Affinity Fund - U.S. Government
Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve Fund - U.S.
Government Series, Cadre Reserve Fund - Money Market Series, Cadre SweepCash
Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market Series, U.S.
Government Money Market Portfolio and Money Market Portfolio. Previously the
Trust offered the Ambac U.S. Treasury Money Market Fund, which ceased operations
on June 30, 1997. The accompanying financial statements and financial highlights
are those of the Cadre Liquid Asset Fund - Money Market Series (the "Fund"). The
Fund commenced operations on May 3, 1999.

The Fund invests all of its investable assets in the Money Market Portfolio (the
"Portfolio"). The Portfolio has the same investment objectives as the Fund.

The value of the Fund's investment in the Portfolio, as reflected in the
Statement of Assets and Liabilities, reflects the Fund's proportionate interest
in the net assets of the Portfolio (5.1% at October 31, 1999.) The Portfolio has
the same investment objectives as the Fund and the performance of the Fund is
directly affected by the performance of the Portfolio. The financial statements
of the Portfolio, including the Schedule of Investments, are included elsewhere
in this report and should be read in conjunction with the Fund's financial
statements.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

VALUATION OF SECURITIES
Valuation of securities by the Portfolio is discussed in Note 2 of the
Portfolio's Notes to Financial Statements, which are included elsewhere in this
report.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE LIQUID ASSET FUND - MONEY MARKET SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999 (CONTINUED)
- --------------------------------------------------------------------------------

INVESTMENT INCOME
The Fund records its proportionate share of net investment income and realized
gains and losses each day. The net investment income and realized gain and loss
of the Portfolio is allocated on a pro-rata basis among the Fund and the other
investors in the Portfolio at the time of such determination.

DIVIDENDS TO SHAREHOLDERS
Substantially all of the Fund's net investment income and net realized capital
gains, if any, are declared as dividends daily and paid monthly. Net short-term
capital gains, if any, will be distributed in accordance with the requirements
of the Internal Revenue Code of 1986, as amended (the "Code"), and may be
reflected in the Fund's daily dividend rate. Substantially all of the realized
net long-term capital gains, if any, are declared and paid annually, except that
an additional capital gains distribution may be made in a given year to the
extent necessary to avoid the imposition of federal excise tax on the Fund.
Income dividends and capital gain distributions are determined in accordance
with income tax regulations, which may differ from generally accepted accounting
principles.

FEDERAL INCOME TAXES
The Trust is treated as a separate entity for federal income tax purposes and
intends to qualify each year as a "regulated investment company" under
Subchapter M of the Code and to make distributions of substantially all of its
income, including net realized capital gains, if any, to relieve it from
substantially all Federal income and excise taxes. Therefore, no Federal tax
provision is required.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.

NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Fund, has entered into an Administration Agreement
with Cadre Financial Services, Inc., a wholly-owned subsidiary of Ambac
Financial Group, Inc., ("Cadre"), under which Cadre is responsible for certain
aspects of the administration and operation of the Fund. For its services, Cadre
is paid an annual fee of 0.19% of the Fund's first $250 million average daily
net assets, 0.165% of the Fund's next $750 million average daily net assets and
0.14% of the Fund's average daily net assets in excess of $1 billion.

The Trust, on behalf of the Fund, has entered into a Transfer Agent Agreement
with Cadre, under which Cadre is responsible for providing shareholder
recordkeeping services to the Fund. For its services, Cadre is paid an annual
fee of 0.05% of the Fund's first $250 million average daily net assets, 0.04% of
the Fund's next $750 million average daily net assets and 0.03% of the Fund's
average daily net assets in excess of $1 billion.

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive distributor of the Trust's shares.

- --------------------------------------------------------------------------------

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.

NOTE 4 - WAIVER OF FEES AND REIMBURSEMENT OF EXPENSES

Cadre has voluntarily agreed to waive a portion of its fees and to reimburse the
Fund for certain expenses to the extent the total operating expenses of the fund
exceed 0.47% (annualized) of the Funds average daily net assets. During the
period May 3, 1999 (commencement of operations) through October 31, 1999, Cadre
waived fees of $42,118 and reimbursed expenses of $49,221 so that the Fund could
meet this expense limitation.

The Fund has adopted an Excess Expense Reimbursement Plan (the "Plan") pursuant
to which the Fund has agreed to reimburse Cadre for any waived fees or
reimbursed expenses to the extent the Fund's total operating expenses go below
the expense limitation of 0.47% (annualized) of the Fund's average daily net
assets. The Plan has a term of three years from its adoption date of March 16,
2002. During the period May 3, 1999 (commencement of operations) through October
31, 1999, the Fund did not reimburse Cadre for any amounts pursuant to the terms
of the Plan.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

To the Shareholders and Board of Trustees of
Cadre Institutional Investors Trust
Money Market Portfolio:

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - Money Market Portfolio (the "Portfolio"),
including the schedule of investment, as of October 31, 1999, and the related
statement of operations and the statement of changes in net assets for the
period May 3, 1999 (commencement of operations) through October 31, 1999. These
financial statements are the responsibility of the Portfolio's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cadre Institutional Investors
Trust - Money Market Portfolio as of October 31, 1999, the results of its
operations and the changes in its net assets for the period May 3, 1999
(commencement of operations) through October 31, 1999, in conformity with
generally accepted accounting principles.

CADRE INSTITUTIONAL INVESTORS TRUST
MONEY MARKET PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------

NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April 1996 as a Delaware business trust and
is registered as an open-end management investment company under the Investment
Company Act of 1940, as amended, (the "1940 Act"). The Trust is comprised of ten
series as follows: Cadre Liquid Asset Fund - U.S. Government Series, Cadre
Liquid Asset Fund - Money Market Series, Cadre Affinity Fund - U.S. Government
Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve Fund - U.S.
Government Series, Cadre Reserve Fund - Money Market Series, Cadre SweepCash
Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market Series, U.S.
Government Money Market Portfolio and Money Market Portfolio (collectively, the
"Funds"). Previously the Trust offered the Ambac U.S. Treasury Money Market
Fund, which ceased operations on June 30, 1997. The accompanying financial
statements and supplementary data are those of the Money Market Portfolio (the
"Portfolio"). The Portfolio commenced operations on May 3, 1999.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements.

VALUATION OF SECURITIES
Investments are valued at amortized cost, which approximates market value. The
amortized cost method of valuation values a security at its cost on the date of
purchase and thereafter assumes a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of instruments.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME
Securities transactions are recorded on a trade date basis. Interest income,
which includes the amortization of discounts and premiums, if any, is recorded
on an accrual basis. Net realized gains and losses on sales of securities are
determined by the identified cost method.

REPURCHASE AGREEMENTS
The Portfolio may engage in repurchase agreement transactions with institutions
that the Trust's adviser has determined are creditworthy pursuant to guidelines
established by the Trust's Board of Trustees. The Portfolio's custodian or
designated custodians, as the case may be under tri-party repurchase agreements,
takes possession of the collateral pledged for investments in

repurchase agreements on behalf of the Portfolio. It is the policy of the
Portfolio to value the underlying collateral daily on a mark-to-market basis to
determine that the value, including accrued interest, is at least equal to the
repurchase price plus accrued interest. In the event of default of the
obligations to repurchase, the Portfolio has the right to liquidate the
collateral and apply the proceeds in satisfaction of the obligations. Under
certain circumstances, in the event of default or bankruptcy by the other party
to the agreement, realization and/or retention of the collateral or proceeds may
be subject to legal proceedings.

FEDERAL INCOME TAXES
The Portfolio intends to be treated as a partnership for federal income tax
purposes. As such, each investor in the Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that the
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended. The cost of securities is
substantially the same for book and tax purposes.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.

NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Fund, has entered into an Investment Advisory
Agreement with Cadre Financial Services, Inc. ("Cadre"), a wholly-owned
subsidiary of Ambac Financial Group, Inc., under which Cadre is responsible for
certain aspects of the administration and operation of the Fund. For its
services, Cadre is paid an annual fee of 0.08% of the Portfolio's average daily
net assets.

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive distributor of the Trust's shares.

Certain officers of the Trust may be officers of the Cadre and/or the
Distributor or their affiliates. Such officers receive no compensation from the
Trust for serving in their respective roles. Trustees who are not employees of
Cadre and/or the Distributor or their affiliated companies, are each paid an
annual retainer of $5,000 and receive an attendance fee of $750 for each meeting
of the Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE AFFINITY FUND - MONEY MARKET SERIES
CIIT CHAIRMAN'S ANNUAL REPORT LETTER
- --------------------------------------------------------------------------------

Dear Shareholders,

As 1999 comes to a close and we stand poised for the new millenium, I cannot
help but reflect on what a year this has been for the Cadre Institutional
Investors Trust (the "Fund"). Since the Fund's inception in 1995, there has not
been such a robust year of development. This year saw the successful
implementation of Y2K readiness projects by our service providers and the full
implementation of the Fund's new master/feeder investment structure. During this
year, we have enjoyed explosive growth of new assets and investors to record
levels.

As many of you know, the Fund developed a master/feeder investment structure to
permit the Fund to expand its distribution channels to new markets and
shareholders, while permitting us to combine investment assets into our master
portfolios. Through this development, the Fund now offers six investment series,
each of which has received a AAA rating. As a result, the total assets of the
Fund have grown to a record high, as of October 31, 1999, of $893 million; and,
the number of shareholders has reached a new high of 335 shareholders. 2000 will
present a significant challenge if we hope to surpass the accomplishments of
1999, but I am confident that the Fund's service agents, Cadre Financial
Services, Inc. and Cadre Securities, Inc. stand ready to meet this challenge.

We will strive hard to exceed our 1999 accomplishments. For 2000, Cadre will
remain focused on the Fund's guiding principles of safety, liquidity and yield,
while continuing two major Fund initiatives -Technology and Education.

As we move into the new millennium, we are all faced with increasing demands and
decreasing resources. We all face the charge "Do more with less". Therefore, we
will increase our focus on one of the most valuable benefits of the Fund - Time.
Through the greater use of technology, we expect that the Fund will yield
greater TIME savings for you and your staff. Technology gives us the ability to
provide you with immediate access to your investments, online, permitting faster
processing time and the ability to conduct business on your time. Cadre has
invested great resources in the Fund's online reporting system, Compass, and
will do even more in 2000. During this coming year, Compass will be further
developed to provide enhanced reporting and transaction capability. Through
Compass, the Fund will continue to benefit its shareholders by reducing the time
spent managing your liquid assets.

Finally, important to us all, is the role of education. In the ever-changing
landscape of investments, it is very demanding to stay abreast of the latest
developments. The investment world is growing in complexity and the demands of
our positions are becoming increasingly challenging. For 2000, Cadre will focus
on providing value-added education in the many areas affecting your role as a
financial officer. Cadre intends to provide valuable investment and technology
seminars designed to help each of us better understand prudent investing and
effective cash management.

These initiatives will be as rewarding as they are difficult, but with your
continued support of the Fund, we are certain they will be accomplished. We look
forward to the millennium ahead.

Sincerely,

William T. Sullivan, Jr.
Chairman

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE AFFINITY FUND - MONEY MARKET SERIES
ECONOMIC OVERVIEW
- --------------------------------------------------------------------------------

In September 1998, the failure of Long Term Capital Management, a large hedge
fund, caused global financial panic, which resulted in a global flight to
quality in the U.S. Treasury market. This flight to quality caused the yield on
the 30-Year Treasury Bond to decline below 4.75%, its lowest level in history.
The Federal Reserve responded by aggressively lowering the overnight bank rate
by 75 basis points. In a period of six weeks, the Fed lowered the Fed Funds
target interest rate, in a series of three 25 basis point moves (from 5.50% to
4.75%), which included a rare inter-meeting move in October of 1998. The decline
in interest rates was a result of the view that the domestic economy would slow
dramatically. However, global financial markets stabilized and the domestic
economy continued to show resilience.

During the period, Gross Domestic Product (GDP) grew at an annualized rate of
4.3% and in the third quarter GDP was up an impressive 5.5%. The consumer has
been the catalyst for this strong economy. The consumer has benefited from a
tight labor market as evidenced by an unemployment rate of 4.1% combined with
the wealth effect, a result of the impressive gains in the stock market. In
fact, in the first quarter of 1999, consumer spending, which accounts for two
thirds of economic activity posted its largest gain in eleven years.

This economic strength combined with a lower rate of unemployment, concerned Fed
officials enough to begin raising the Fed Funds target interest rate. In fact,
beginning on June 30th of 1999, the Fed embarked on a series of three 25 basis
point rate increases, with the most recent move occurring on November 16th. This
last move completely reversed all the monetary stimulus provided by the Fed in
the fourth quarter of 1998.

Although the economy continues to grow at a brisk pace and the Fed has responded
by reversing all of the reductions of 1998, inflation still remains absent. The
GDP price deflator, a measure of price increases followed by many investors,
rose at a 1.1% pace in the third quarter, down from the 1.4% rate of the
previous quarter. This data mirrors other inflationary measures. The Producer
Price Index (PPI) decreased .1% in October and excluding the volatile food and
energy components, the core PPI increased .3%. Through October, core PPI has
risen at a .9% annual rate, down from a 1.6% rate during the first ten months of
last year. Prices also remain well behaved at the consumer level. The Consumer
Price Index (CPI) increased .2% in October and the core CPI increased .2%.
Through October, core CPI has risen at a 1.9% annual rate, down from a 2.0% rate
during the first ten months of last year

Despite the unemployment rate being at its lowest level since 1970, wages remain
well under control. The employment cost index (ECI) increased .9% in the third
quarter and benefit costs rose .8%. For the twelve months ended September 30th
the ECI rose 3.1%, down from a 3.7% increase for the 12 month period ended
September 30th 1998.

Worker productivity has played a large role in the economy's ability to maintain
a low unemployment rate with little signs of inflation. In the third quarter,
worker productivity increased at a 4.2% annual rate, which was the largest gain
since the first quarter of 1998.

In the statement that accompanied the November rate increase, the Fed stated
that "the pool of available workers willing to take jobs has been drawn down
further in recent months, a trend that must eventually be contained if
inflationary imbalances are to remain in check." Therefore, we believe that
continued tightening of the labor market or signs of inflation could force
another Fed rate increase by the first quarter of 2000.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

To the Shareholders and Board of Trustees of Cadre Institutional Investors Trust
Cadre Affinity Fund - Money Market Series:

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - Cadre Affinity Fund - Money Market Series (the
"Fund"), as of October 31, 1999, and the related statements of operations,
changes in net assets and the financial highlights for the period May 3, 1999
(commencement of operations) through October 31, 1999. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Cadre
Institutional Investors Trust - Cadre Affinity Fund - Money Market Series as of
October 31, 1999, the results of its operations, the changes in its net assets,
and the financial highlights for the period May 3, 1999 (commencement of
operations) through October 31, 1999, in conformity with generally accepted
accounting principles.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE AFFINITY FUND - MONEY MARKET SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------

NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April 1996 as a Delaware business trust and
is registered as an open-end management investment company under the Investment
Company Act of 1940, as amended (the "1940 Act"). The Trust is comprised of ten
series as follows: Cadre Liquid Asset Fund - U.S. Government Series, Cadre
Liquid Asset Fund - Money Market Series, Cadre Affinity Fund - U.S. Government
Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve Fund - U.S.
Government Series, Cadre Reserve Fund - Money Market Series, Cadre SweepCash
Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market Series, U.S.
Government Money Market Portfolio and Money Market Portfolio. Previously the
Trust offered the Ambac U.S. Treasury Money Market Fund, which ceased operations
on June 30, 1997. The accompanying financial statements and financial highlights
are those of the Cadre Affinity Fund - Money Market Series (the "Fund"). The
Fund commenced operations on May 3, 1999.

The Fund invests all of its investable assets in the Money Market Portfolio (the
"Portfolio"). The portfolio has the same investment objective as the Fund.

The value of the Fund's investment in the Portfolio, as reflected in the
Statement of Assets and Liabilities, reflects the Fund's proportionate interest
in the net assets of the Portfolio (7.0% at October 31, 1999.) The Portfolio has
the same investment objective as the Fund and the performance of the Fund is
directly affected by the performance of the Portfolio. The financial statements
of the Portfolio, including the Schedule of Investments, are included elsewhere
in this report and should be read in conjunction with the Fund's financial
statements.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

VALUATION OF SECURITIES
Valuation of securities by the Portfolio is discussed in Note 2 of the
Portfolio's Notes to Financial Statements, which are included elsewhere in this
report.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE AFFINITY FUND - MONEY MARKET SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999 (CONTINUED)
- --------------------------------------------------------------------------------

INVESTMENT INCOME
The Fund records its proportionate share of net investment income and realized
gains and losses each day. The net investment income and realized gain and loss
of the Portfolio is allocated on a pro-rata basis among the Fund and the other
investors in the Portfolio at the time of such determination.

DIVIDENDS TO SHAREHOLDERS
Substantially all of the Fund's net investment income and net realized capital
gains, if any, are declared as dividends daily and paid monthly. Net short-term
capital gains, if any, will be distributed in accordance with the requirements
of the Internal Revenue Code of 1986, as amended (the "Code"), and may be
reflected in the Fund's daily dividend rate. Substantially all of the realized
net long-term capital gains, if any, are declared and paid annually, except that
an additional capital gains distribution may be made in a given year to the
extent necessary to avoid the imposition of federal excise tax on the Fund.
Income dividends and capital gain distributions are determined in accordance
with income tax regulations, which may differ from generally accepted accounting
principles.

FEDERAL INCOME TAXES
The Trust is treated as a separate entity for federal income tax purposes and
intends to qualify each year as a "regulated investment company" under
Subchapter M of the Code and to make distributions of substantially all of its
income, including net realized capital gains, if any, to relieve it from
substantially all Federal income and excise taxes. Therefore, no Federal tax
provision is required.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.

NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Fund, has entered into an Administration Agreement
with Cadre Financial Services, Inc., a wholly-owned subsidiary of Ambac
Financial Group, Inc., ("Cadre"), under which Cadre is responsible for certain
aspects of the administration and operation of the Fund. For its services, Cadre
is paid an annual fee of 0.19% of the Fund's first $250 million average daily
net assets, 0.165% of the Fund's next $750 million average daily net assets and
0.14% of the Fund's average daily net assets in excess of $1 billion.

The Trust, on behalf of the Fund, has entered into a Transfer Agent Agreement
with Cadre, under which Cadre is responsible for providing shareholder
recordkeeping services to the Fund. For its services, Cadre is paid an annual
fee of 0.05% of the Fund's first $250 million average daily net assets, 0.04% of
the Fund's next $750 million average daily net assets and 0.03% of the Fund's
average daily net assets in excess of $1 billion.

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive distributor of the Trust's shares.

- --------------------------------------------------------------------------------

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.

NOTE 4 - WAIVER OF FEES AND REIMBURSEMENT OF EXPENSES

Cadre has voluntarily agreed to waive a portion of its fees and to reimburse the
Fund for certain expenses to the extent the total operating expenses of the find
exceed 0.57% (annualized) of the Funds average daily net assets. During the
period May 3, 1999 (commencement of operations) through October 31, 1999, Cadre
waived fees of $36,349 and reimbursed expenses of $29,610 so that the Fund could
meet this expense limitation.

The Fund has adopted an Excess Expense Reimbursement Plan (the "Plan") pursuant
to which the Fund has agreed to reimburse Cadre for any waived fees or
reimbursed expenses to the extent the Fund's total operating expenses go below
the expense limitation of 0.57% (annualized) of the Fund's average daily net
assets. The Plan has a term of three years from its adoption date of March 16,
2002. During the period May 3, 1999 (commencement of operations) through October
31, 1999, the Fund did not reimburse Cadre for any amounts pursuant to the terms
of the Plan.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

To the Shareholders and Board of Trustees of
Cadre Institutional Investors Trust
Money Market Portfolio:

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - Money Market Portfolio (the "Portfolio"),
including the schedule of investment, as of October 31, 1999, and the related
statement of operations and the statement of changes in net assets for the
period May 3, 1999 (commencement of operations) through October 31, 1999. These
financial statements are the responsibility of the Portfolio's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cadre Institutional Investors
Trust - Money Market Portfolio as of October 31, 1999, the results of its
operations and the changes in its net assets for the period May 3, 1999
(commencement of operations) through October 31, 1999, in conformity with
generally accepted accounting principles.

Liquid Asset Fund - Money Market Series, Cadre Affinity Fund - U.S. Government
Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve Fund - U.S.
Government Series, Cadre Reserve Fund - Money Market Series, Cadre SweepCash
Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market Series, U.S.
Government Money Market Portfolio and Money Market Portfolio (collectively, the
"Funds"). Previously the Trust offered the Ambac U.S. Treasury Money Market
Fund, which ceased operations on June 30, 1997. The accompanying financial
statements and supplementary data are those of the Money Market Portfolio (the
"Portfolio"). The Portfolio commenced operations on May 3, 1999.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements.

VALUATION OF SECURITIES
Investments are valued at amortized cost, which approximates market value. The
amortized cost method of valuation values a security at its cost on the date of
purchase and thereafter assumes a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of instruments.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME
Securities transactions are recorded on a trade date basis. Interest income,
which includes the amortization of discounts and premiums, if any, is recorded
on an accrual basis. Net realized gains and losses on sales of securities are
determined by the identified cost method.

REPURCHASE AGREEMENTS
The Portfolio may engage in repurchase agreement transactions with institutions
that the Trust's adviser has determined are creditworthy pursuant to guidelines
established by the Trust's Board of Trustees. The Portfolio's custodian or
designated custodians, as the case may be under tri-party repurchase agreements,
takes possession of the collateral pledged for investments in

repurchase agreements on behalf of the Portfolio. It is the policy of the
Portfolio to value the underlying collateral daily on a mark-to-market basis to
determine that the value, including accrued interest, is at least equal to the
repurchase price plus accrued interest. In the event of default of the
obligations to repurchase, the Portfolio has the right to liquidate the
collateral and apply the proceeds in satisfaction of the obligations. Under
certain circumstances, in the event of default or bankruptcy by the other party
to the agreement, realization and/or retention of the collateral or proceeds may
be subject to legal proceedings.

FEDERAL INCOME TAXES
The Portfolio intends to be treated as a partnership for federal income tax
purposes. As such, each investor in the Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that the
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended. The cost of securities is
substantially the same for book and tax purposes.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.

NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Fund, has entered into an Investment Advisory
Agreement with Cadre Financial Services, Inc. ("Cadre"), a wholly-owned
subsidiary of Ambac Financial Group, Inc., under which Cadre is responsible for
certain aspects of the administration and operation of the Fund. For its
services, Cadre is paid an annual fee of 0.08% of the Portfolio's average daily
net assets.

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive distributor of the Trust's shares.

Certain officers of the Trust may be officers of the Cadre and/or the
Distributor or their affiliates. Such officers receive no compensation from the
Trust for serving in their respective roles. Trustees who are not employees of
Cadre and/or the Distributor or their affiliated companies, are each paid an
annual retainer of $5,000 and receive an attendance fee of $750 for each meeting
of the Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.

CADRE RESERVE FUND - MONEY MARKET SERIES
CIIT CHAIRMAN'S ANNUAL REPORT LETTER
- --------------------------------------------------------------------------------

Dear Shareholders,

As 1999 comes to a close and we stand poised for the new millenium, I cannot
help but reflect on what a year this has been for the Cadre Institutional
Investors Trust (the "Fund"). Since the Fund's inception in 1995, there has not
been such a robust year of development. This year saw the successful
implementation of Y2K readiness projects by our service providers and the full
implementation of the Fund's new master/feeder investment structure. During this
year, we have enjoyed explosive growth of new assets and investors to record
levels.

As many of you know, the Fund developed a master/feeder investment structure to
permit the Fund to expand its distribution channels to new markets and
shareholders, while permitting us to combine investment assets into our master
portfolios. Through this development, the Fund now offers six investment series,
each of which has received a AAA rating. As a result, the total assets of the
Fund have grown to a record high, as of October 31, 1999, of $893 million; and,
the number of shareholders has reached a new high of 335 shareholders. 2000 will
present a significant challenge if we hope to surpass the accomplishments of
1999, but I am confident that the Fund's service agents, Cadre Financial
Services, Inc. and Cadre Securities, Inc. stand ready to meet this challenge.

We will strive hard to exceed our 1999 accomplishments. For 2000, Cadre will
remain focused on the Fund's guiding principles of safety, liquidity and yield,
while continuing two major Fund initiatives -Technology and Education.

As we move into the new millennium, we are all faced with increasing demands and
decreasing resources. We all face the charge "Do more with less". Therefore, we
will increase our focus on one of the most valuable benefits of the Fund - Time.
Through the greater use of technology, we expect that the Fund will yield
greater TIME savings for you and your staff. Technology gives us the ability to
provide you with immediate access to your investments, online, permitting faster
processing time and the ability to conduct business on your time. Cadre has
invested great resources in the Fund's online reporting system, Compass, and
will do even more in 2000. During this coming year, Compass will be further
developed to provide enhanced reporting and transaction capability. Through
Compass, the Fund will continue to benefit its shareholders by reducing the time
spent managing your liquid assets.

Finally, important to us all, is the role of education. In the ever-changing
landscape of investments, it is very demanding to stay abreast of the latest
developments. The investment world is growing in complexity and the demands of
our positions are becoming increasingly challenging. For 2000, Cadre will focus
on providing value-added education in the many areas affecting your role as a
financial officer. Cadre intends to provide valuable investment and technology
seminars designed to help each of us better understand prudent investing and
effective cash management.

These initiatives will be as rewarding as they are difficult, but with your
continued support of the Fund, we are certain they will be accomplished. We look
forward to the millennium ahead.

Sincerely,

William T. Sullivan, Jr.
Chairman

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE RESERVE FUND - MONEY MARKET SERIES
ECONOMIC OVERVIEW
- --------------------------------------------------------------------------------

In September 1998, the failure of Long Term Capital Management, a large hedge
fund, caused global financial panic, which resulted in a global flight to
quality in the U.S. Treasury market. This flight to quality caused the yield on
the 30-Year Treasury Bond to decline below 4.75%, its lowest level in history.
The Federal Reserve responded by aggressively lowering the overnight bank rate
by 75 basis points. In a period of six weeks, the Fed lowered the Fed Funds
target interest rate, in a series of three 25 basis point moves (from 5.50% to
4.75%), which included a rare inter-meeting move in October of 1998. The decline
in interest rates was a result of the view that the domestic economy would slow
dramatically. However, global financial markets stabilized and the domestic
economy continued to show resilience.

During the period, Gross Domestic Product (GDP) grew at an annualized rate of
4.3% and in the third quarter GDP was up an impressive 5.5%. The consumer has
been the catalyst for this strong economy. The consumer has benefited from a
tight labor market as evidenced by an unemployment rate of 4.1% combined with
the wealth effect, a result of the impressive gains in the stock market. In
fact, in the first quarter of 1999, consumer spending, which accounts for two
thirds of economic activity posted its largest gain in eleven years.

This economic strength combined with a lower rate of unemployment, concerned Fed
officials enough to begin raising the Fed Funds target interest rate. In fact,
beginning on June 30th of 1999, the Fed embarked on a series of three 25 basis
point rate increases, with the most recent move occurring on November 16th. This
last move completely reversed all the monetary stimulus provided by the Fed in
the fourth quarter of 1998.

Although the economy continues to grow at a brisk pace and the Fed has responded
by reversing all of the reductions of 1998, inflation still remains absent. The
GDP price deflator, a measure of price increases followed by many investors,
rose at a 1.1% pace in the third quarter, down from the 1.4% rate of the
previous quarter. This data mirrors other inflationary measures. The Producer
Price Index (PPI) decreased .1% in October and excluding the volatile food and
energy components, the core PPI increased .3%. Through October, core PPI has
risen at a .9% annual rate, down from a 1.6% rate during the first ten months of
last year. Prices also remain well behaved at the consumer level. The Consumer
Price Index (CPI) increased .2% in October and the core CPI increased .2%.
Through October, core CPI has risen at a 1.9% annual rate, down from a 2.0% rate
during the first ten months of last year

Despite the unemployment rate being at its lowest level since 1970, wages remain
well under control. The employment cost index (ECI) increased .9% in the third
quarter and benefit costs rose .8%. For the twelve months ended September 30th
the ECI rose 3.1%, down from a 3.7% increase for the 12 month period ended
September 30th 1998.

Worker productivity has played a large role in the economy's ability to maintain
a low unemployment rate with little signs of inflation. In the third quarter,
worker productivity increased at a 4.2% annual rate, which was the largest gain
since the first quarter of 1998.

In the statement that accompanied the November rate increase, the Fed stated
that "the pool of available workers willing to take jobs has been drawn down
further in recent months, a trend that must eventually be contained if
inflationary imbalances are to remain in check." Therefore, we believe that
continued tightening of the labor market or signs of inflation could force
another Fed rate increase by the first quarter of 2000.

                          INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Trustees of Cadre Institutional Investors Trust
Cadre Reserve Fund - Money Market Series:

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - Cadre Reserve Fund - Money Market Series (the
"Fund"), as of October 31, 1999, and the related statements of operations,
changes in net assets and the financial highlights for the period May 3, 1999
(commencement of operations) through October 31, 1999. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Cadre
Institutional Investors Trust - Cadre Reserve Fund - Money Market Series as of
October 31, 1999, the results of its operations, the changes in its net assets,
and the financial highlights for the period May 3, 1999 (commencement of
operations) through October 31, 1999, in conformity with generally accepted
accounting principles.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE RESERVE FUND - MONEY MARKET SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------

NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April 1996 as a Delaware business trust and
is registered as an open-end management investment company under the Investment
Company Act of 1940, as amended (the "1940 Act"). The Trust is comprised of ten
series as follows: Cadre Liquid Asset Fund - U.S. Government Series, Cadre
Liquid Asset Fund - Money Market Series, Cadre Affinity Fund - U.S. Government
Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve Fund - U.S.
Government Series, Cadre Reserve Fund - Money Market Series, Cadre SweepCash
Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market Series, U.S.
Government Money Market Portfolio and Money Market Portfolio. Previously the
Trust offered the Ambac U.S. Treasury Money Market Fund, which ceased operations
on June 30, 1997. The accompanying financial statements and financial highlights
are those of the Cadre Reserve Fund - Money Market Series (the "Fund"). The Fund
commenced operations on May 19, 1999.

The Fund invests all of its investable assets in the Money Market Portfolio (the
"Portfolio"). The Portfolio has the same investment objective as the Fund.

The value of the Fund's investment in the Portfolio, as reflected in the
Statement of Assets and Liabilities, reflects the Fund's proportionate interest
in the net assets of the Portfolio (0.3% at October 31, 1999.) The Portfolio has
the same investment objective as the Fund and the performance of the Fund is
directly affected by the performance of the Portfolio. The financial statements
of the Portfolio, including the Schedule of Investments, are included elsewhere
in this report and should be read in conjunction with the Fund's financial
statements.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

VALUATION OF SECURITIES
Valuation of securities by the Portfolio is discussed in Note 2 of the
Portfolio's Notes to Financial Statements, which are included elsewhere in this
report.

CADRE INSTITUTIONAL INVESTORS TRUST
CADRE RESERVE FUND - MONEY MARKET SERIES
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1999
- --------------------------------------------------------------------------------

INVESTMENT INCOME
The Fund records its proportionate share of net investment income and realized
gains and losses each day. The net investment income and realized gain and loss
of the Portfolio is allocated on a pro-rata basis among the Fund and the other
investors in the Portfolio at the time of such determination.

DIVIDENDS TO SHAREHOLDERS
Substantially all of the Fund's net investment income and net realized capital
gains, if any, are declared as dividends daily and paid monthly. Net short-term
capital gains, if any, will be distributed in accordance with the requirements
of the Internal Revenue Code of 1986, as amended (the "Code"), and may be
reflected in the Fund's daily dividend rate. Substantially all of the realized
net long-term capital gains, if any, are declared and paid annually, except that
an additional capital gains distribution may be made in a given year to the
extent necessary to avoid the imposition of federal excise tax on the Fund.
Income dividends and capital gain distributions are determined in accordance
with income tax regulations, which may differ from generally accepted accounting
principles.

FEDERAL INCOME TAXES
The Trust is treated as a separate entity for federal income tax purposes and
intends to qualify each year as a "regulated investment company" under
Subchapter M of the Code and to make distributions of substantially all of its
income, including net realized capital gains, if any, to relieve it from
substantially all Federal income and excise taxes. Therefore, no Federal tax
provision is required.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.

NOTE 3 - TRANSACTIONS WITH AFFILIATES

The Trust, on behalf of the Fund, has entered into an Administration Agreement
with Cadre Financial Services, Inc., a wholly-owned subsidiary of Ambac
Financial Group, Inc., ("Cadre"), under which Cadre is responsible for certain
aspects of the administration and operation of the Fund. For its services, Cadre
is paid an annual fee of 0.10% of the Fund's first $250 million average daily
net assets, 0.075% of the Fund's next $750 million average daily net assets and
0.05% of the Fund's average daily net assets in excess of $1 billion.

The Trust, on behalf of the Fund, has entered into a Transfer Agent Agreement
with Cadre, under which Cadre is responsible for providing shareholder
recordkeeping services to the Fund. For its services, Cadre is paid an annual
fee of 0.05% of the Fund's first $250 million average daily net assets, 0.04% of
the Fund's next $750 million average daily net assets and 0.03% of the Fund's
average daily net assets in excess of $1 billion.

Cadre Securities, Inc. (the "Distributor"), a wholly-owned subsidiary of Ambac
Financial Group, Inc., acts as the exclusive distributor of the Trust's shares.

NOTES TO FINANCIAL STATEMENTS

- --------------------------------------------------------------------------------

Certain officers of the Trust may be officers of Cadre and/or the Distributor or
their affiliates. Such officers receive no compensation from the Trust for
serving in their respective roles. Trustees who are not employees of Cadre
and/or the Distributor or their affiliated companies, are each paid an annual
retainer of $5,000 and receive an attendance fee of $750 for each meeting of the
Board of Trustees they attend. Members of the Audit Committee receive an
attendance fee of $750 for each Audit Committee meeting they attend. The
Chairman of the Audit Committee receives an additional $1,000 annual fee.
Officers of the Trust receive no compensation from the Trust.

NOTE 4 - WAIVER OF FEES AND REIMBURSEMENT OF EXPENSES

Cadre has voluntarily agreed to waive a portion of its fees and to reimburse the
Fund for certain expenses to the extent the total operating expenses of the fund
exceed 0.22% (annualized) of the Funds average daily net assets. During the
period May 19, 1999 (commencement of operations) through October 31, 1999, Cadre
waived fees of $5,401 and reimbursed expenses of $ 54,177 so that the Fund could
meet this expense limitation.

The Fund has adopted an Excess Expense Reimbursement Plan (the "Plan") pursuant
to which the Fund has agreed to reimburse Cadre for any waived fees or
reimbursed expenses to the extent the Fund's total operating expenses go below
the expense limitation of 0.22% (annualized) of the Fund's average daily net
assets. The Plan has a term of three years from its adoption date of March 16,
2002. During the period May 19, 1999 (commencement of operations) through
October 31, 1999, the Fund did not reimburse Cadre for any amounts pursuant to
the terms of the Plan.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

To the Shareholders and Board of Trustees of
Cadre Institutional Investors Trust
Money Market Portfolio:

We have audited the accompanying statement of assets and liabilities of Cadre
Institutional Investors Trust - Money Market Portfolio (the "Portfolio"),
including the schedule of investment, as of October 31, 1999, and the related
statement of operations and the statement of changes in net assets for the
period May 3, 1999 (commencement of operations) through October 31, 1999. These
financial statements are the responsibility of the Portfolio's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of October 31, 1999, by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cadre Institutional Investors
Trust - Money Market Portfolio as of October 31, 1999, the results of its
operations and the changes in its net assets for the period May 3, 1999
(commencement of operations) through October 31, 1999, in conformity with
generally accepted accounting principles.

NOTE 1 - ORGANIZATION

Cadre Institutional Investors Trust (the "Trust") (formerly known as Ambac
Treasurer's Trust), was organized in April 1996 as a Delaware business trust and
is registered as an open-end management investment company under the Investment
Company Act of 1940, as amended, (the "1940 Act"). The Trust is comprised of ten
series as follows: Cadre Liquid Asset Fund - U.S. Government Series, Cadre
Liquid Asset Fund - Money Market Series, Cadre Affinity Fund - U.S. Government
Series, Cadre Affinity Fund - Money Market Series, Cadre Reserve Fund - U.S.
Government Series, Cadre Reserve Fund - Money Market Series, Cadre SweepCash
Fund - U.S. Government Series, Cadre SweepCash Fund - Money Market Series, U.S.
Government Money Market Portfolio and Money Market Portfolio (collectively, the
"Funds"). Previously the Trust offered the Ambac U.S. Treasury Money Market
Fund, which ceased operations on June 30, 1997. The accompanying financial
statements and supplementary data are those of the Money Market Portfolio (the
"Portfolio"). The Portfolio commenced operations on May 3, 1999.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements.

VALUATION OF SECURITIES
Investments are valued at amortized cost, which approximates market value. The
amortized cost method of valuation values a security at its cost on the date of
purchase and thereafter assumes a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of instruments.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME
Securities transactions are recorded on a trade date basis. Interest income,
which includes the amortization of discounts and premiums, if any, is recorded
on an accrual basis. Net realized gains and losses on sales of securities are
determined by the identified cost method.

REPURCHASE AGREEMENTS
The Portfolio may engage in repurchase agreement transactions with institutions
that the Trust's adviser has determined are creditworthy pursuant to guidelines
established by the Trust's Board of Trustees. The Portfolio's custodian or
designated custodians, as the case may be under tri-party repurchase agreements,
takes possession of the collateral pledged for investments in

NOTES TO FINANCIAL STATEMENTS

repurchase agreements on behalf of the Portfolio. It is the policy of the
Portfolio to value the underlying collateral daily on a mark-to-market basis to
determine that the value, including accrued interest, is at least equal to the
repurchase price plus accrued interest. In the event of default of the
obligations to repurchase, the Portfolio has the right to liquidate the
collateral and apply the proceeds in satisfaction of the obligations. Under
certain circumstances, in the event of default or bankruptcy by the other party
to the agreement, realization and/or retention of the collateral or proceeds may
be subject to legal proceedings.

FEDERAL INCOME TAXES
The Portfolio intends to be treated as a partnership for federal income tax
purposes. As such, each investor in the Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that the
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended. The cost of securities is
substantially the same for book and tax purposes.

EXPENSES
Expenses incurred by the Trust with respect to any two or more funds in the
Trust are allocated in proportion to the net assets of each fund, except where
allocation of direct expenses to each fund can otherwise be made fairly.
Expenses directly attributable to a fund are charged to that fund.
