Dear Shareholder:

We are pleased to present the semi-annual report for the Smith Barney Adjustable
Rate Government Income Fund ("Fund") for the period ended November 30, 1999. We
hope you find this report useful and informative. The prevailing economic and
market conditions and a summary 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.

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 to achieve these objectives by investing
primarily in adjustable rate mortgage-backed securities ("ARMs"), U.S.
government securities and asset-backed securities. The Fund calculates an NAV
daily and reports the Class A share's NAV listing in national newspapers under
the heading Smith Barney Funds A as "AdjGvA".

As of November 30, 1999, the Fund's Class A shares had an NAV of $9.65. For the
six-month period, the Fund's Class A shares posted a total return of 1.66%
without sales charges, underperforming the Merrill Lynch 1-3 Year U.S. Treasury
Index's return of 2.04%. (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.)
The Fund's performance was also slightly lower than the Lipper, Inc. U.S.
Government 1-Year Treasury Bill Index, which posted a return of 1.95% over the
same period. (Lipper, Inc. is a major fund-tracking organization.)

Bond Market Update
The U.S. economy continued to grow during the reporting period as U.S. exports
and manufacturing industries began to rebound. Additionally, consumer strength
remains an important contributor to U.S. economic growth as low unemployment and
rising personal income fuel domestic demand. Despite inflationary concerns as

measured by the Consumer Price Index ("CPI")1 and the Producer Price Index
("PPI")2 remaining relatively benign, the Federal Reserve Board ("Fed") adopted
a tightening bias and raised short-term interest rates in June, August and
November. Following the latest interest-rate hike, the Fed indicated that it
believed that growth "continues in excess of the economy's growth potential."
Nevertheless, the Fed adopted a neutral bias regarding inflation.

U.S. Treasury yields rose over the period, with the yield of the two-year
Treasury increasing by 60 basis points from 5.41% to 6.01%. (A basis point is a
measure of fluctuation of an investment equal to 1/100 of one percent or 0.01%.)
In the opinion of Blackrock Financial Management Inc. ("Blackrock"), the Fund's
sub-investment adviser, bond prices, which move inversely to their yields,
declined due to investor response to strong economic data and the overall
market's uncertainty regarding Fed policy. Recently, a weaker U.S. dollar,
higher commodity prices and strong gains in the U.S. and European stock markets
have also depressed overall demand for bonds.

Mortgage-backed securities outperformed the broader domestic investment-grade
fixed income markets during the period, as the Lehman Brothers Mortgage Bond
Index3 posted a 1.21% total return versus 0.72% for the Lehman Brothers
Aggregate Bond Index.4 Higher interest rates throughout the period helped to
alleviate prepayment fears and pushed mortgage rates above 8% for the first time
since 1997. Additionally, new mortgage issuance declined in response to lower
refinancing activity across all coupons, providing, in the investment team's
view, favorable technical conditions for mortgage-backed securities.

Investment Strategy

The investment objectives of the Fund are to seek to provide high current income
and to limit the degree of fluctuation of its net asset value resulting from
movements in interest rates.

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 dollar weighted average life (or period
until next interest rate reset date) between one and three years, resulting in a
fund whose NAV performance should be similar to that of a one- or two-year U.S.
Treasury security. Changes in the prices and yields of these Treasury securities
affect the value of the Fund's securities. In addition to interest rates,
prepayment rates of the mortgage securities held in the portfolio usually affect
the Fund's NAV.

------------
1 The CPI measures prices of a fixed basket of goods bought by a typical
  consumer, including food, transportation, utilities, clothing, entertainment
  and medical care.
2 The PPI measures the change in wholesale prices as released monthly by the
  U.S. Bureau of Labor Statistics.
3 The Lehman Brothers Mortgage Bond Index is a broad measure of the performance
  of mortgage-backed bonds in the U.S. market.
4 The Lehman Brothers Aggregate Bond Index is a broad measure of the performance
  of taxable bonds in the U.S. market, with maturities of at least one year.

--------------------------------------------------------------------------------
2                                        1999 Semi-Annual Report to Shareholders

The Fund's assets are actively managed based on the Fund's subadviser, relative
value analysis of individual securities and sectors. In searching for relative
value opportunities, the BlackRock team targets securities and market sectors
within the short duration market that have underperformed and may have strong
potential for price appreciation. (Of course, past performance is not indicative
of future results.)

After generally maintaining the Fund's allocation to the ARMs sector steady for
nearly two years, the Fund became a net buyer of ARMs during the third quarter
of 1999 as that sector decreased in price due to higher new issuance. Higher
interest rates and a steeper yield curve have spurred the new issuance of ARMs,
with ARMs now accounting for nearly one third of all mortgage issuance versus
only 10% a year ago. (The yield curve measures the difference between short- and
long-term rates.) In particular, the BlackRock team found excellent relative
value in hybrid ARMs, which begin as fixed-rate mortgages and then convert into
adjustable-rate securities. The team continues to find floating-rate, asset-
backed securities and Small Business Administration Loans attractive due to
their compelling yields and potentially strong credit quality, and the Fund
added to its holdings in these areas.

Market Outlook
BlackRock expects that a neutral to negative stance on the bond market may be
warranted as economic pressures build. The combination of higher stock and
commodity prices, confident consumers, continued tightening of labor markets and
a global recovery that should boost U.S. exports and reduce the trade deficit
may lead to higher interest rates.

Despite the strength in the U.S. economy, increased productivity gains have so
far succeeded in offsetting inflationary pressures. For example, the PPI for
November 1999 rose marginally by 0.2%, illustrating that fierce competition is
keeping a lid on costs as the global economy continues to expand. However,
BlackRock believes that continued economic growth will invariably lead to
inflationary pressures and a possible rise in interest rates by the Fed in early
2000.

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

Sincerely,

/s/ Heath B. McLendon

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 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 by class; (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. At May 31, 1999, reclassifications
were made to the Fund's capital accounts to reflect permanent book/tax
differences and income and gains available for distributions under income tax
regulations. Accordingly, a portion of overdistributed net investment income
amounting to $24,208 was 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.

2.   Investment Advisory Agreement,
     Administration Agreement and Other Transactions

SSB Citi Fund Management LLC ("SSBC"), formerly known as SSBC Fund Management
Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH") which, in
turn, is a subsidiary of Citigroup Inc. ("Citigroup"), acts as investment
adviser to the Fund. The Fund pays SSBC 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.

--------------------------------------------------------------------------------
Smith Barney Adjustable Rate Government Income Fund                           17

--------------------------------------------------------------------------------
Notes to Financial Statements (unaudited)(continued)
--------------------------------------------------------------------------------
SSBC 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-
today portfolio operations and investment decisions for the Fund. SSBC 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.

SSBC 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.

Effective October 1999, Smith Barney Private Trust Company, another subsidiary
of Citigroup, became the Fund's transfer agent and PFPC Global Fund Services
became the Fund's sub-transfer agent. During the period October 1, 1999 through
November 30, 1999, the Fund paid transfer agent fees of $9,239 to Smith Barney
Private Trust Company.

CFBDS, Inc. acts as the Fund's distributor. Salomon Smith Barney Inc. ("SSB"),
another subsidiary of SSBH, as well as certain other broker-dealers, continues
to sell Fund shares to the public as a member of the selling group.

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 the purchase of
a previously held fund (held by the shareholder prior to exchange into this
Fund) and declines thereafter by 1.00% per year until no CDSC is incurred. For
the six months ended November 30, 1999, CDSCs paid to SSB or CFBDS for Class B
shares were approximately $7,000.

Pursuant to a Distribution Plan, the Fund pays a service fee with respect to
Class A, B, 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 and B shares calculated at an annual rate of 0.50% of
the average daily net assets of each class. For the six months ended November
30, 1999, total Distribution Plan fees incurred were:

                                          Class A      Class B     Class I
================================================================================
Distribution Plan Fees                   $403,603       $8,880     $37,182
================================================================================

All officers and one Trustee of the Fund are employees of SSB.

3.  Investments

During the six months ended November 30, 1999, the aggregate cost of purchases
and proceeds from sales of investments (including maturities, but excluding
paydowns and short-term securities) were as follows:

================================================================================
Purchases                                                          $178,245,513
--------------------------------------------------------------------------------
Sales                                                               107,004,682
================================================================================

At November 30, 1999, aggregate gross unrealized appreciation and de preciation
of investments for Federal income tax purposes were substantially as follows:

================================================================================
Gross unrealized appreciation                                       $   141,299
Gross unrealized depreciation                                        (1,304,127)
--------------------------------------------------------------------------------
Net unrealized depreciation                                         $(1,162,828)
================================================================================

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 and accretion of income recognized on investment securities.

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.

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 as
collateral under the reverse repurchase agreement.

At November 30, 1999, the Fund had the following reverse repurchase agreements
outstanding:

 FACE
AMOUNT                                SECURITY                             VALUE

                  Multi ARM, 5.945% due 7/1/01                        32,448,000
--------------------------------------------------------------------------------
                TOTAL REVERSE REPURCHASE AGREEMENTS                  $35,952,000
================================================================================

During the six months ended November 30, 1999, the maximum and average amount of
reverse repurchase agreements outstanding at month ends were as follows:

================================================================================
Maximum amount outstanding                                           $39,034,494
--------------------------------------------------------------------------------
Average amount outstanding                                           $12,500,642
================================================================================

Interest rates ranged from 4.50% to 5.58% during the year. Total market value of
the collateral for the reverse repurchase agreements is $37,693,036.

Interest expense for the six months ended November 30, 1999 on borrowings by the
Fund under reverse repurchase agreements totalled $293,700.

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 received on the
sale, will generate income for the Fund exceeding the yield on the securities
sold.

At November 30, 1999, 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.

At November 30, 1999, the Fund did not hold any TBA securities.

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.

At November 30, 1999, the Fund had one purchased call option contract with a
total cost of $42,500.


--------------------------------------------------------------------------------
Smith Barney Adjustable Rate Government Income Fund                           21

--------------------------------------------------------------------------------
Notes to Financial Statements (unaudited) (continued)
--------------------------------------------------------------------------------
When the 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.

The following covered call option transactions occurred during the six months
ended November 30, 1999:

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).

At November 30, 1999, the Fund had the following open futures contracts:

                      Expiration    # of       Basis       Market    Unrealized

At November 30, 1999, 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 shares are available for
purchase to certain investors in the Smith Barney 401(k) Program. In addition,

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 November 30, 1999, total paid-in capital amounted to the following for each
class:

                                          Class A       Class B       Class I
