SMITH BARNEY ADJUSTABLE RATE GOVERNMENT INCOME FUND
================================================================================


Dear Shareholder:

We are pleased to present the annual report for the Smith Barney Adjustable Rate
Government Income Fund ("Fund") for the year ended May 31, 1997. The period's
prevailing economic and market conditions and an outline of our investment
strategy appear in this report. In addition, a detailed summary of the Fund's
historical performance as well as its current holdings and portfolio management
strategy can be found in the appropriate sections that follow.

Fund Performance Update

The Fund's investment objective is to seek high current income and to limit the
degree of fluctuation of its net asset value (NAV) resulting from movements in
interest rates. The Fund seeks these objectives by investing primarily in a
portfolio of adjustable rate mortgage-backed securities (ARMs), U.S. government
securities and asset-backed securities (ABS). The Fund calculates an NAV daily
and Class A share's NAV is reported in the mutual funds listing in national
newspapers under the heading Smith Barney Funds A as "AdjGvA."

As of May 31, 1997, the Fund's Class A shares had an NAV of $9.84. For the
year-to-date period ended May 31, 1997, the Fund's Class A shares outperformed
the Merrill Lynch 1-3 Year U.S. Treasury Index by posting a total return of
2.21% versus 1.46%. The Fund's outperformance reflects the strong performance of
ARMs and other short duration alternatives to U.S. Treasuries. (The Merrill
Lynch 1-3 Year U.S. Treasury Index is a market capitalization weighted index
including all U.S. Treasury Notes and Bonds with maturities greater than or
equal to one year and less than three years.)

For the year ended May 31, 1997, the Class A shares of the Fund had a total
return of 5.31%. In comparison, the Fund's Lipper Analytical Services, Inc. peer
group generated an average return of 6.50% for the same period. (Lipper
Analytical Services, Inc. is a major fund tracking organization.)

Bond Market Update

In our view, the domestic bond market's performance during the last year was
driven by two factors: the pace of economic growth and resulting investor
concerns over potential rising inflation. After a strong second quarter of 1996,


                                                                               1

the pace of economic growth slowed during the remainder of last year to a
2%-2.5% annual level, which is viewed by many economists as a non-inflationary
growth rate. Economic data indicating slow growth and continued moderation in
broad inflation measures, such as consumer spending, enabled the Federal Reserve
Board ("Fed") to leave short-term interest rates unchanged at their August and
September policy meetings. However, stronger economic data from the government
and growing concerns about inflation caused U.S. Treasury yields to rise in late
1996 and for much of 1997. After reaching their lowest levels since March of
1996, U.S. Treasury yields began rising in December 1996 after Fed Chairman Alan
Greenspan's much publicized concerns of "irrational exuberance" in the financial
markets. Although inflationary measures such as commodity and producer prices
have remained relatively stable, employment growth remained strong.

The combination of a robust economy, relatively low unemployment and strong
consumer confidence prompted the Fed to raise the federal funds rate by 25 basis
points (0.25%) at their March 25, 1997, monetary policy meeting. (The federal
funds rate is the interest rate banks charge each other for overnight loans and
is a closely watched indicator of the direction of interest rates.) However,
government reports released in April and May appeared to indicate moderate
economic growth and relatively tame inflation causing the bond market to
subsequently rally. Particularly important during these two months were the
Fed's lack of action at its May 20, 1997 meeting and a lower-than-expected
upward revision to the first quarter's Gross Domestic Product (GDP) figure.

Despite experiencing significant swings, the yield of the 2-year U.S. Treasury
Note ended the year at 6.20%, which is slightly lower then where it began on May
31, 1996. Over the year, investor demand for spread product (i.e., bonds that
offer higher yields compared to U.S. Treasuries) enabled most other taxable
fixed income asset classes to outperform U.S. Treasuries. For instance,
mortgage-backed securities (MBS), which represent a major portion of the Fund's
holdings, posted good relative performance primarily due to low interest rate
volatility and relatively low refinancing risk. Over the period, the MBS market
as measured by the Lehman Mortgage Index (The Lehman Mortgage Index covers all
fixed-rate securities backed by mortgage pools of the Government National
Mortgage Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC), and
Federal National Mortgage Association (FNMA).) generated a total return of 2.63%
versus the U.S. Treasury market's return as measured by the Merrill Lynch 5-7
Year U.S. Treasury Index of 1.04%. (The Merrill Lynch 5-7 Year U.S. Treasury
Index is a market capitalization weighted index including all U.S. Treasury
Notes and Bonds with maturities greater than or equal to five years and less
than seven years.)

Within the short maturity sector of the market, ARMs and ABS also posted
excellent relative performance. We believe that the ARM market has benefited
from improving fundamental conditions over the past two years, as interest rate
volatility has generally remained at historically low levels. This has resulted
in some portions of the ARM market, particularly "seasoned," or older production
securities, to reform particularly well versus comparable maturity U.S.
Treasuries. In our view, the ABS market also has benefited from low interest
rate volatility as the best performing ABS in 1996 were those securities backed
by home equity loans.

Fund's Investment Strategy

Duration is a rough measure of the price sensitivity of a fixed income security
relative to a given change in interest rates. The Fund uses a "targeted
duration" approach which strives for a duration of roughly 1 to 1.5 years and
should result in a fund whose NAV performance is similar to that of a 1- or
2-year U.S. Treasury security. Changes in the prices and yields of these U.S.
Treasury securities affect the value of the Fund's securities. In addition to
interest rates, the prepayment rates of the mortgage-backed securities held in
the portfolio usually affects the Fund's NAV.

The Fund's assets are actively managed based on our relative value analysis of
individual securities and sectors. In searching for relative value
opportunities, we target securities and market sectors within the short duration
market that have underperformed and have strong potential for price
appreciation. During the reporting period, the Fund substantially increased its
exposure to the floating-rate ABS and collateralized mortgage obligations
(CMOs). We increased the weightings to these sectors by selling ARMs and fixed
rate ABS, both of which had performed well during the period under review.

Bond Market Outlook

Our outlook for the bond market is cautiously optimistic. Over the short term,
we believe that the recent rally may continue, since inflation news has been
positive (Consumer Price Index registered a year-over-year increase of just
2.3%) and U.S. securities appear inexpensive relative to their global
counterparts. Additionally, Fed Chairman Alan Greenspan appears to be
comfortable with the "new paradigm" that productivity gains may allow the
economy to expand at a faster clip without igniting price pressures. Thus, we do
not foresee another Fed tightening in 1997 in the absence of a visible inflation
shock.

However, the tight labor market is still a cause for concern. Many investors
anxiously await the turning point when low unemployment and lean staffing levels
led many employees to shed the insecurity from the corporate


                                                                               3

restructurings of the early 1990s and demand higher wages. Moreover, recent wage
increases, the buoyant stock market and record levels of consumer confidence are
expected to lead to stronger consumer spending and overall economic growth in
the third quarter. Therefore, we think an uninterrupted decline in yields is by
no means a certainty.

In closing, thank you for investing in the Smith Barney Adjustable Rate
Government Income Fund. We look forward to continuing to help you achieve your
financial goals.

Sincerely,

/s/ Heath B. McLendon

Heath B. McLendon

Adjustable Rate Mortgage-Backed Securities (ARMs) are instruments that bear
interest at rates that adjust at periodic intervals at a fixed amount over the
market levels of interest rates as reflected in specified indexes. ARMs directly
or indirectly represent an interest in, or are backed by and are payable from
mortgage loans secured by real property.

Asset-Backed Securities are similar in structure to Mortgage-Backed Securities,
except that the underlying asset pools consist of credit card, automobile or
other types of receivables, or of commercial loans.

Collateralized Mortgage Obligations (CMOs) are Mortgage-Backed Securities
collateralized by mortgage loans or mortgage pass-through securities. Typically,
CMOs are collateralized by GNMA, FNMA or FHLMC Mortgage Pass-Through
Certificates, but also may be collateralized by whole loans or private mortgage
pass-through securities.

Planned Amortization Class Interest Only (PAC IOs) are CMO IOs which have
repayment schedules that are guaranteed if the actual speed of the prepayments
is within a designated range. PAC classes typically are combined with companion
classes that reduce the risk of the variation of the amount and timing of the
prepayments. Should the prepayments fall outside of the PAC band or ranges, the
class will not pay the prepayment as scheduled.

     1. SIGNIFICANT ACCOUNTING POLICIES

     The Smith Barney Adjustable Rate Government Income Fund ("Fund"), a
Massachusetts business trust, is registered under the Investment Company Act of
1940, as amended, as a diversified, open-end management investment company.

     The significant accounting policies followed by the Fund are: (a) security
transactions are accounted for on trade date; (b) U.S. government agencies and
obligations are valued at the quoted bid price in the over-the-counter market;
corporate debt securities, mortgage-backed securities and asset-backed
securities are valued on the basis of valuations provided by dealers in those
instruments or by an independent pricing service approved by the Fund's Board of
Trustees; (c) securities maturing within 60 days are valued at cost plus
accreted discount, or minus amortized premium, which approximates value; (d)
interest income, adjusted for accretion of original issue discount, is recorded
on an accrual basis; (e) dividends and distributions to shareholders are
recorded on the ex-dividend date; (f) gains or losses on the sale of securities
are calculated by using the specific identification method; (g) direct expenses
are charged to each class; management fees and general fund expenses are
allocated on the basis of relative net assets; (h) the Fund intends to comply
with the requirements of the Internal Revenue Code of 1986, as amended,
pertaining to regulated investment companies and to make distributions of
taxable income sufficient to relieve it from substantially all Federal income
and excise taxes; (i) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. Accordingly, overdistributed income of
$804,871 at May 31, 1997 have been reclassified to paid-in capital. Net
investment income, net realized gains and net assets were not affected by this
change; and (j) estimates and assumptions are required to be made regarding
assets, liabilities and changes in net assets resulting from operations when
financial statements are prepared. Changes in the economic environment,
financial markets and any other parameters used in determining these estimates
could cause actual results to differ.

     In addition, organization costs have been deferred and amortized on a
straight-line basis over a five year period, beginning with the commencement of
the Fund's operations in June 1992.

     2. INVESTMENT ADVISORY AGREEMENT, ADMINISTRATION AGREEMENT AND OTHER
        TRANSACTIONS

investment adviser to the Fund. The Fund pays SBSA an investment advisory fee
calculated at the annual rate of 0.40% of the average daily net assets. This fee
is calculated daily and paid monthly.

     SBSA has entered into a sub-advisory agreement with BlackRock Financial
Management Inc. ("BlackRock"), a wholly owned subsidiary of PNC Bank, N.A.
Pursuant to the sub-advisory agreement, BlackRock is responsible for the
day-to-day portfolio operations and investment decisions for the Fund. SBSA pays
BlackRock a monthly fee calculated at an annual rate of 0.20% of the average
daily net assets of the Fund. This fee is calculated daily and paid monthly.

     SBMFM also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the average daily net assets. This fee
is calculated daily and paid monthly.

     Smith Barney Inc. ("SB"), another subsidiary of SBH, acts as distributor of
the Fund's shares.

     There is a maximum contingent deferred sales charge ("CDSC") of 5.00% on
Class B shares, which applies if redemption occurs within one year from initial
purchase and declines thereafter by 1.00% per year until no CDSC is incurred.
For the year ended May 31, 1997, CDSCs paid to SB for Class B shares were
approximately $22,000.

     Pursuant to a Distribution Plan, the Fund pays a service fee with respect
to Class A, B, C, and I shares calculated at the annual rate of 0.25% of the
average daily net assets of each respective class. The Fund also pays a
distribution fee with respect to Class A, B and C shares calculated at an annual
rate of 0.50% of the average daily net assets of each class. For the year ended

     During the year ended May 31, 1997, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding
short-term securities) were as follows:

</TABLE>


     4. CASH FLOW INFORMATION

     Cash, as used in the Statement of Cash Flows, is the amount reported in the
Statement of Assets and Liabilities. The Fund issues and redeems its shares,
invests in securities and distributes dividends from net investment income and
net realized gains (which are either paid in cash or reinvested into the Fund at
the discretion of shareholders). These activities are reported in the Statement
of Changes in Net Assets. Information on cash payments is presented in the
Statement of Cash Flows. Accounting practices that do not affect reporting
activities on a cash basis include unrealized gain or loss on investment
securities, accretion income recognized on investment securities and
amortization of deferred organization costs.

     5. REPURCHASE AGREEMENTS

     The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day) at
an agreed-upon higher repurchase price. The Fund requires continual maintenance
of the market value of the collateral in amounts equal to the repurchase price.

     As of May 31, 1997, the Fund had no open repurchase agreements.

     6. REVERSE REPURCHASE AGREEMENTS

     The Fund may enter into reverse repurchase agreement transactions for
leveraging purposes. A reverse repurchase agreement involves a sale by the Fund
of securities that it holds with an agreement by the Fund to repurchase the same
securities at an agreed upon price and date. A reverse repurchase agreement
involves the risk that the market value of the securities sold by the Fund may
decline below the repurchase price of the securities. The Fund will establish a
segregated account with its custodian, in which the Fund will maintain cash,
U.S. government securities or other liquid high grade debt obligations equal in
value to its obligations with respect to the reverse repurchase agreements.


                                                                              19

================================================================================

     7. DOLLAR ROLL TRANSACTIONS

     The Fund may enter into dollar roll transactions. A dollar roll transaction
involves a sale by the Fund of securities that it holds with an agreement by the
Fund to repurchase similar securities at an agreed upon price and date. The
securities repurchased will bear the same interest as those sold, but generally
will be collateralized by pools of mortgages with different prepayment histories
than those securities sold. Proceeds of the sale will be invested and the income
from these investments, together with any additional income for the Fund
exceeding the yield on the securities sold.

     As of May 31, 1997, the Fund had no open dollar roll transactions.

     8. SECURITIES TRADED ON A TO-BE-ANNOUNCED BASIS

     The Fund may trade securities on a "to-be-announced" ("TBA") basis. In a
TBA transaction, the Fund commits to purchasing or selling securities for which
specific information is not yet known at the time of the trade, particularly the
face amount and maturity date in GNMA transactions. Securities purchased on a
TBA basis are not settled until they are delivered to the Fund, normally 15 to
45 days later. These transactions are subject to market fluctuations and their
current value is determined in the same manner as for other securities.

     As of May 31, 1997, the Fund held one TBA security with a cost of
$2,000,000.

     9. OPTIONS CONTRACTS

     Premiums paid when put or call options are purchased by the Fund, represent
investments, which are marked-to-market daily and are included in the schedule
of investments. When a purchased option expires, the Fund will realize a loss in
the amount of the premium paid. When the Fund enters into a closing sales
transaction, the Fund will realize a gain or loss depending on whether the sales
proceeds from the closing sales transaction are greater or less than the premium
paid for the option. When the Fund exercises a put option, it will realize a
gain or loss from the sale of the underlying security and the proceeds from such
a sale will be decreased by the premium originally paid. When the Fund exercises
a call option, the cost of the security which the Fund purchases upon exercise
will be increased by the premium originally paid.

     As of May 31, 1997, the Fund had no open purchased put or call option
contracts.


                                                                              21
<PAGE>
 
================================================================================
Notes to Financial Statements (continued)
================================================================================

     When a Fund writes a covered call or put option, an amount equal to the
premium received by the Fund is recorded as a liability, the value of which is
marked-to-market daily. When a written option expires, the Fund realizes a gain
equal to the amount of the premium received. When the Fund enters into a closing
purchase transaction, the Fund realizes a gain (or loss if the cost of the
closing purchase transaction exceeds the premium received when the option was
written) without regard to any unrealized gain or loss on the underlying
security, and the liability related to such an option is eliminated. When a
written call option is exercised, the cost of the security sold will be
decreased by the premium originally received. When a written put option is
exercised, the amount of the premium originally received will reduce the cost of
the security which the Fund purchased upon exercise. When written index options
are exercised, settlement is made in cash.

     The risk associated with purchasing options is limited to the premium
originally paid. The Fund enters into options for hedging purposes. The risk in
writing a covered call option is that the Fund gives up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Fund is exposed to
the risk of loss if the market price of the underlying security declines.

     During the year ended May 31, 1997, the Fund did not write any options.

     10. FUTURES CONTRACTS

     Initial margin deposits made upon entering into futures contracts are
recognized as assets. Securities equal to the initial margin amount are
segregated by the custodian in the name of the broker. Additional securities are
also segregated up to the current market value of the futures contracts. During
the period the futures contract is open, changes in the value of the contract
are recognized as unrealized gains or losses by "marking-to-market" on a daily
basis to reflect the market value of the contract at the end of each day's
trading. Variation margin payments are received or made and recognized as assets
due from or liabilities due to broker, depending upon whether unrealized gains
or losses are incurred. When the contract is closed, the Fund records a realized
gain or loss equal to the difference between the proceeds from (or cost of) the
closing transactions and the Fund's basis in the contract. The Fund enters into
such contracts to hedge a portion of its portfolio. The Fund bears the market
risk that arises from changes in the value of the financial instruments and
securities indices (futures contracts) and the credit risk should a counterparty
fail to perform under such contracts.

</TABLE>


     11. SHORT SALES OF SECURITIES

     A short sale is a transaction in which the Fund sells securities it does
not own (but has borrowed) in anticipation of a decline in the market price of
the securities. To complete a short sale, the Fund may arrange through a broker
to borrow the securities to be delivered to the buyer. The proceeds received by
the Fund for the short sale are retained by the broker until the Fund replaces
the borrowed securities. In borrowing the securities to be delivered to the
buyer, the Fund becomes obligated to replace the securities borrowed at their
market price at the time of replacement, whatever that price may be.

     During the year ended May 31, 1997, the Fund did enter into several short
sale transactions; however, at the end of the year all these transactions had
closed and there were no open transactions.

     12. CAPITAL LOSS CARRYFORWARD

     As of May 31, 1997, the Fund had, for Federal income tax purposes,
approximately $6,685,000 of capital loss carryforwards available to offset any
future capital gains. To the extent that these carryforward losses are used to
offset capital gains, it is probable that the gains so offset will not be
distributed. The amount and expiration of the carryforwards are indicated below.
Expiration occurs on May 31 of the year indicated:

     13. SHARES OF BENEFICIAL INTEREST

     At May 31, 1997, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Fund has the
ability to issue multiple classes of shares. Class B and C shares are available
for


                                                                              23

purchase to investors in the Smith Barney 401(k) Program. In addition, Class B
shares can be purchased through exchanges. Each share represents an identical
interest in the Fund and has the same rights except that each class bears
certain expenses specifically related to the distribution of its shares.

     At May 31, 1997, total paid-in capital amounted to the following for each
class:

responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the two-year period ended May 31, 1995 and
for the period from June 22, 1992 (commencement of operations) to May 31, 1993,
were audited by other auditors whose report thereon, dated July 26, 1995,
expressed an unqualified opinion on those financial highlights.

     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 May
31, 1997, 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 the
Smith Barney Adjustable Rate Government Income Fund as of May 31, 1997, the
results of its operations and cash flows for the year then ended, and the
changes in its net assets and financial highlights for each of the years in the
two-year period then ended, in conformity with generally accepted accounting
principles.
