Chairman, President and Chief Executive Officer



Dear Shareholder,
The philosopher Bertrand Russell famously remarked that, "Change is one thing,
progress is another." You will notice in the following pages that we have begun
to implement some changes to your shareholder report and we will be reflecting
other changes in future reports. Our aim is to make meaningful improvements in
reporting on the management of your Fund and its performance, not just to enact
change for change's sake. Please bear with us during this transition period.

I invite you to read this report in full. Please take the opportunity to talk
to your financial adviser about this report or any other questions or concerns
you have about your Fund and your financial future. As always, thank you for
entrusting your assets to us. We look forward to helping you continue to meet
your financial goals.

Sincerely,

/s/ R. Jay Gerken
R. Jay Gerken
Chairman, President and Chief Executive Officer

which they are traded and; securities for which no sales price was reported and
U.S. government agencies and obligations are valued at the mean between the bid
and asked prices; (c) securities maturing within 60 days are valued at cost
plus accreted discount or minus amortized premium, which approximates value;
(d) securities for which market quotations are not available will be valued in
good faith at fair value by or under the direction of the Board of Directors;
(e) interest income, adjusted for amortization of premium and accretion of
discount, is recorded on an accrual basis; (f) dividend income is recorded on

in foreign currencies are translated into U.S. dollars based on the rate of
exchange of such currencies against U.S. dollars on the date of valuation.
Purchases and sales of securities, and income and expenses are translated at
the rate of exchange quoted on the respective date that such transactions are
recorded. Differences between income or expense amounts recorded and collected
or paid are adjusted when reported by the custodian; (j) the character of
income and gains to be distributed are determined in accordance with income tax
regulations which may differ from accounting principles generally accepted in
the United States of America; (k) the Funds intend to comply with the
applicable provisions 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; and (l) 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. Management Agreement and Transactions with Affiliated Persons

Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary
of Citigroup Inc. ("Citigroup") acts as investment manager of the Smith Barney

sub-transfer agent. CTB receives account fees and asset-based fees that vary

4. 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 contract.
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 Funds record 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.
