WHAT IS YOUR ANALYSIS OF THE INTEREST RATE ENVIRONMENT DURING THE
12-MONTH FISCAL YEAR?

Although it did not occur until near the very end of the reporting
period, the fiscal year was marked by the first change in monetary
policy in over a year. On March 25, 1997, the Federal Reserve Board
(the "Fed"), in the face of stronger than expected demand, voted to
raise the federal funds target rate from 5.25% to 5.50%. The move was
viewed as being preemptive against the threat of future inflationary
pressures, possibly brought about by tight labor market conditions.

Until that point, movements in interest rates reflected shifting
market sentiment about the need for the Fed to move to a more
restrictive policy. The second quarter of 1996 was characterized by
much stronger than expected growth and fueled by consumer spending and
housing. Signs of slower growth began to emerge in the third quarter
of 1996, temporarily allaying market fears about inflation, but then
picked up once again through the fourth quarter of 1996 and into 1997.
With inflation still appearing to be benign, the market tolerated the
pace of growth over this period. However, Fed Chairman Alan
Greenspan's Humphrey-Hawkins Testimony before Congress in late
February marked a turning point for the short-term government market
- -- and the bond and equity markets as well. At the meeting, his
relatively hawkish statements revealed fears at the Fed that the
transitory factors, which had been keeping inflation under control in
the face of fairly robust growth, may be coming to an end. The ensuing
weeks brought continued evidence of persistent strength, which ended
in the Fed's action at the Federal Open Market Committee in late
March.

For most of the reporting period, movements in short-term interest
rates bounced back and forth as sentiment swayed regarding the need
for a more restrictive policy. The yield on the six-month Treasury
bill, for example, rose from 5.00% at the beginning of April to 5.50%
in early June as conviction grew that the next change in monetary
policy might be a tightening. The next few months were characterized
by significant market volatility and debate over the sustainability of
the economy. Interest rate movements reflected the uncertainty -- the
yield on the six-month Treasury bill rose to 5.60% in early July, fell
to 5.30% by early August, rose to 5.60% by early September, and,
finally, fell to 5.25% by the end of the month. Rates then traded
within a range over the fourth quarter and into early 1997 -- with the
six-month Treasury bill moving between 5.20% to 5.40% -- as the
continued friendly inflation picture provided some comfort to market
participants. Finally, rates began to rise in late February, and by
the time the Fed tightened in late March, had built in much of the
expectation regarding the move. The six-month bill rose steadily from
5.20% to close at 5.60% by the end of the reporting period.

WHAT WERE YOUR STRATEGIES FOR LIBERTY U.S. GOVERNMENT MONEY MARKET TRUST
DURING THE REPORTING PERIOD?

As signs of economic strength became more apparent, we lowered the
average maturity target range of the trust from between 40 and 50 days
to between 35 and 45 days in early June, and remained in that range
throughout the remainder of the reporting period. As expectation of an
imminent Fed tightening grew in the first quarter of 1997, we moved
the average maturity of the portfolio to the lower half of the target
range in anticipation of higher interest rates.

Once an average maturity range is targeted, the portfolio seeks to
maximize performance through ongoing relative value analysis. The
trust reduced its exposure to the Treasury market in favor of
government agency securities, as the yield advantage offered in this
sector proved attractive. The trust's portfolio remained barbelled in
structure, which combined a significant portion in repurchase
agreements and floating rate securities with purchases of longer-term
securities with six- to twelve-month Treasury and government agency
securities. This portfolio structure continued to provide a
competitive yield.

WHAT IS YOUR OUTLOOK FOR RATES FOR THE BALANCE OF 1997?

Although current expectations are that the Fed will find cause to
tighten monetary policy further in 1997 -- perhaps as soon as in the
second quarter -- it is also anticipated that the overall tightening
cycle will not be long in terms of magnitude or duration. The
preemptive move by the Fed should help to preclude the need for more
aggressive action down the road by preventing the buildup of
inflationary pressures. We would look to see moderately higher
short-term interest rates throughout the course of the year, but not
to the extent evidenced in the last tightening cycle in 1994. As such,
we will likely continue in our modestly defensive stance for the
portfolio until market conditions indicate otherwise.

LIBERTY U.S. GOVERNMENT MONEY MARKET TRUST
NOTES TO FINANCIAL STATEMENTS

MARCH 31, 1997

1. ORGANIZATION

Liberty U.S. Government Money Market Trust (the "Trust") is registered
under the Investment Company Act of 1940, as amended (the "Act"), as a
open-end management investment company. The Trust offers two classes
of shares: Class A Shares and Class B Shares. The investment objective
of the Trust is stability of principal and current income consistent
with stability of principal.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies
consistently followed by the Trust in the preparation of its financial
statements. These policies are in conformity with generally accepted
accounting principles.

INVESTMENT VALUATIONS -- The Trust's use of the amortized cost method
to value its portfolio securities is in accordance with Rule 2a-7
under the Act.

REPURCHASE AGREEMENTS -- It is the policy of the Trust to require the
custodian bank to take possession, to have legally segregated in the
Federal Reserve Book Entry System, or to have segregated within the
custodian bank's vault, all securities held as collateral under
repurchase agreement transactions. Additionally, procedures have been
established by the Trust to monitor, on a daily basis, the market
value of each repurchase agreement's collateral to ensure that the
value of collateral at least equals the repurchase price to be paid
under the repurchase agreement transaction.

The Trust will only enter into repurchase agreements with banks and
other recognized financial institutions, such as broker/dealers, which
are deemed by the Trust's adviser to be creditworthy pursuant to the
guidelines and/or standards reviewed or established by the Board of
Trustees (the "Trustees"). Risks may arise from the potential
inability of counterparties to honor the terms of the repurchase
agreement. Accordingly, the Trust could receive less than the
repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS -- Interest income and
expenses are accrued daily. Bond premium and discount, if applicable,
are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the
ex-dividend date.

FEDERAL TAXES -- It is the Trust's policy to comply with the
provisions of the Code applicable to regulated investment companies
and to distribute to shareholders each year substantially all of its
income. Accordingly, no provisions for federal tax are necessary.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS -- The Trust may engage
in when-issued or delayed delivery transactions. The Trust records
when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make
payment for the securities purchased. Securities purchased on a
when-issued or delayed delivery basis are marked to market daily and
begin earning interest on the settlement date.

USE OF ESTIMATES -- The preparation of financial statements in
conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the amounts
of assets, liabilities, expenses and revenues reported in the
financial statements. Actual results could differ from those
estimated.

OTHER -- Investment transactions are accounted for on the trade date.

3. SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest (without
par value) for each class of shares.

Transactions in shares were as follows:

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of
LIBERTY U.S. GOVERNMENT MONEY MARKET TRUST:

We have audited the accompanying statement of assets and liabilities
of Liberty U.S. Government Money Market Trust (a Massachusetts
business trust), including the schedule of portfolio of investments,
as of March 31, 1997, and the related statement of operations for the
year then ended, the statement of changes in net assets for each of
the two years in the period then ended, and the financial highlights
for each of the periods presented. These financial statements and
financial highlights are the responsibility of the Trust's management.
Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

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 March 31, 1997, by
correspondence with the custodian and brokers. 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 Liberty U.S. Government Money Market Trust as of
March 31, 1997, the results of its operations for the year then ended,
the changes in its net assets for each of the two years in the period
then ended, and financial highlights for the period presented, in
conformity with generally accepted accounting principles.

Mutual funds are not bank deposits or obligations, are not guaranteed
by any bank, and are not insured or guaranteed by the U.S. government,
the Federal Deposit Insurance Corporation, the Federal Reserve Board,
or any other government agency. Investment in mutual funds involves
investment risk, including the possible loss of principal. Although
money market funds seek to maintain a stable net asset value of $1.00
per share, there is no assurance that they will be able to do so.

This report is authorized for distribution to prospective investors
only when preceded or accompanied by the trust's prospectus which
contains facts concerning its objective and policies, management fees,
expenses, and other information.
