Semi-Annual Report to Shareholders 1

To Our Shareholders,

We are pleased to provide you with Legg Mason Income Trust’s semi-annual report for the period ended June 30, 2006, combining reports for the Legg Mason Core Bond Fund, High Yield Portfolio, Investment Grade Income Portfolio and Limited Duration Bond Portfolio.

The following table summarizes key statistics for the Primary Class of each portfolio, as of June 30, 2006:


					Net Asset Value
	SEC Yield^A		Average Life		Per Share

Core Bond		5.04%		9.62 years	$	9.40
High Yield		7.11%		7.52 years	$	8.95
Investment Grade		5.72%		10.16 years	$	10.03
Limited Duration		4.94%		3.07 years	$	10.11

For the period ended June 30, 2006, total returns for the Primary Class of shares of the Core Bond, High Yield, Investment Grade and Limited Duration Portfolios were -1.22%, +3.77%, - -1.15%, and +1.15%, respectively. Total returns for the Institutional Class of shares of the High Yield, Investment Grade and Limited Duration Portfolios were +4.08%, -0.90%, and +1.40%, respectively. (Total return measures investment performance in terms of appreciation or depreciation in a portfolio’s net asset value per share, plus dividends and any capital gain distributions.)

For each of our Funds, historical performance is not indicative of future results, and the principal value of the Core Bond, High Yield, Investment Grade and Limited Duration Portfolios will fluctuate so that shares, when redeemed, may be worth more or less than their original cost.

At a special meeting of shareholders of Legg Mason U.S. Government Money Market Portfolio, shareholders approved a Plan of Liquidation, Dissolution and Termination of the Fund. The Fund’s assets were liquidated on February 27, 2006. Details of the shareholder meeting results can be found in the notes to financial statements.


^A	SEC yields are for the 30 days ended June 30, 2006, and are the average annualized net investment income per share for this period. Yields are subject to change at any time.

2 Semi-Annual Report to Shareholders

Many of our shareholders regularly add to their Primary Class Fund holdings by authorizing automatic, monthly transfers from their bank checking or brokerage accounts. Dollar cost averaging is a convenient and sensible way to invest, as it encourages continued purchases over time regardless of fluctuating price levels. Of course, it does not ensure a profit nor protect against declines in the value of your investment. Your financial adviser will be happy to help you establish a dollar cost averaging plan should you wish to do so.


	Sincerely,



John F. Curley, Jr. Chairman		Mark R. Fetting President

Semi-Annual Report to Shareholders 3

Expense Example

Core Bond Fund

As a shareholder of the Fund, you incur ongoing costs, including management fees, distribution and service (12b-1) fees, and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. Each example is based on an investment of $1,000 invested on January 1, 2006, and held through June 30, 2006.

Actual Expenses

The first line in the table below provides information about actual account values and actual expenses for the Fund. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line in the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare these 5% hypothetical examples with the 5% hypothetical examples that appear in the shareholder reports of other funds.

The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio of 1.00% multiplied by the average value over the period, multiplied by the number of days in the most recent fiscal half-year (181), and divided by 365.

Performance Information

Core Bond Fund

The graph on the following page compares the Fund’s total returns to that of a closely matched broad-based securities market index. The graph illustrates the cumulative total return of an initial $10,000 investment in the Fund’s Primary Class shares, for the periods indicated. The line for the Fund represents the total return after deducting all Fund investment management and other administrative expenses and the transaction costs of buying and selling securities. The line representing the securities market index does not include any transaction costs associated with buying and selling securities in the index or other administrative expenses. Both the Fund’s and the index’s results assume reinvestment of all dividends and distributions.

Total return measures investment performance in terms of appreciation or depreciation in a fund’s net asset value per share, plus dividends and any capital gain distributions. It assumes that dividends and distributions were reinvested at the time they were paid. Average annual returns tend to smooth out variations in a fund’s return, so that they differ from actual year-to-year results.

The performance data quoted represents past performance and does not guarantee future results. The performance stated may have been due to extraordinary market conditions, which may not be duplicated in the future. Current performance may be lower or higher than the performance data quoted. To obtain the most recent month-end performance information please visit www.leggmasonfunds.com. The investment return and principal value of the Fund will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than the original cost. Calculations assume reinvestment of dividends and capital gain distributions. Performance would have been lower if fees had not been waived in various periods.

The graph and table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.


^A	A market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed rate, publicly placed, dollar-denominated, and nonconvertible investment grade debt issues with at least $100 million par amount outstanding and with at least one year to final maturity. Index returns are for the periods beginning February 29, 2004.

Semi-Annual Report to Shareholders 27

Expense Example

High Yield Portfolio

As a shareholder of the Fund, you incur ongoing costs, including management fees, distribution and service (12b-1) fees on Primary Class shares; and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. Each example is based on an investment of $1,000 invested on January 1, 2006, and held through June 30, 2006.

Actual Expenses

The first line for each class in the table below provides information about actual account values and actual expenses for each class. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line for each class in the table below provides information about hypothetical account values and hypothetical expenses based on the relevant class’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the class’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare these 5% hypothetical examples with the 5% hypothetical examples for the relevant class that appear in the shareholder reports of other funds.


		Beginning		Ending		Expenses Paid^A
		Account		Account		During the
		Value		Value		Period
		1/1/06		6/30/06		1/1/06 to 6/30/06

Primary Class:
	Actual	$	1,000.00	$	1,037.70	$	7.33
	Hypothetical (5% return before expenses)		1,000.00		1,017.60		7.25
Institutional Class:
	Actual	$	1,000.00	$	1,040.80	$	4.81
	Hypothetical (5% return before expenses)		1,000.00		1,020.08		4.76

These calculations are based on expenses incurred in the most recent fiscal half-year. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratios of 1.45% and 0.95% for the Primary Class and Institutional Class, respectively, multiplied by the average values over the period, multiplied by the number of days in the most recent fiscal half-year (181), and divided by 365.

The graphs on the following pages compare the Fund’s total returns to that of two closely matched broad-based securities market indices. The graphs illustrate the cumulative total return of an initial $10,000 investment in the Primary Class and an initial $1,000,000 investment in the Institutional Class of the Fund, for the periods indicated. The lines for the Fund represent the total return after deducting all Fund investment management and other administrative expenses and the transaction costs of buying and selling securities. The line representing the securities market index does not include any transaction costs associated with buying and selling securities in the index or other administrative expenses. Both the Fund’s and the index’s results assume reinvestment of all dividends and distributions.

Performance Information

Investment Grade Income Portfolio

The graphs on the following pages compare the Fund’s total returns to that of two closely matched broad-based securities market indices. The graphs illustrate the cumulative total return of an initial $10,000 investment in Primary Class shares and an initial $1,000,000 investment in Institutional Class shares of the Fund, for the periods indicated. The lines for the Fund represent the total return after deducting all Fund investment management and other administrative expenses and the transaction costs of buying and selling securities. The line representing each securities market index does not include any transaction costs associated with buying and selling securities in the index or other administrative expenses. Both the Fund’s and the indices results assume reinvestment of all dividends and distributions.

Performance Information

Limited Duration Bond Portfolio

The graphs on the following pages compare the Fund’s total returns to those of closely matched broad-based securities market indices. The lines illustrate the cumulative total return of an initial $10,000 investment in Primary Class shares and an initial $1,000,000 investment in Institutional Class shares of the Fund, for the periods indicated. The lines for the Fund represent the total return after deducting all Fund investment management and other administrative expenses and the transaction costs of buying and selling securities. The lines representing each securities market index do not include any transaction costs associated with buying and selling securities in the index or other administrative expenses. Both the Fund’s and the indices’ results assume reinvestment of all dividends and distributions.

Prior to August 31, 2004, the Fund was known as the Legg Mason U.S. Government Intermediate-Term Portfolio and followed a policy of investing at least 80% of its assets in securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities, or repurchase agreements secured by such investments, with a dollar-weighted average portfolio maturity between three and ten years. The Fund’s performance prior to such change might have been better or worse had the Fund been managed in accordance with its current objective, policies and strategies.

Notes to Financial Statements

Legg Mason Income Trust, Inc.

(Amounts in Thousands) (Unaudited)

1. Organization and Significant Accounting Policies:

The Legg Mason Income Trust, Inc. (“Corporation”), consisting of the Core Bond Fund (“Core Bond”), the High Yield Portfolio (“High Yield”), the Investment Grade Income Portfolio (“Investment Grade”), and the Limited Duration Bond Portfolio, (“Limited Duration”) (each a “Fund”), is registered under the Investment Company Act of 1940 (“1940 Act”), as amended, as an open-end, diversified investment company.

The High Yield, Investment Grade and Limited Duration Portfolios consist of two classes of shares: Primary Class and Institutional Class. The income and expenses of each of these Funds are allocated proportionately to the two classes of shares based on daily net assets, except for Rule 12b-1 distribution fees, which are charged only on Primary Class shares, and transfer agent and shareholder servicing expenses, which are determined separately for each class.

Preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements:

Security Valuation

Securities owned by the Funds for which market quotations are readily available are valued at current market value. Securities for which market quotations are not readily available are fair valued pursuant to procedures approved by and under the general oversight of the Board of Directors. In determining fair value, all relevant qualitative and quantitative factors available are considered. These factors are subject to change over time and are reviewed periodically. The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized, since such amounts depend on future developments inherent in long-term investments. Further, because of the inherent uncertainty of valuation, those estimated values may differ significantly from quoted or published values or from the values that would have been used had a ready market of the investments existed, and the differences could be material.

With respect to High Yield, where a security is traded on more than one market, which may include foreign markets, the securities are generally valued on the market considered by the Fund’s adviser to be the primary market. The Fund will value its foreign securities in U.S. dollars on the basis of the then-prevailing exchange rates.

Semi-Annual Report to Shareholders 99

Foreign Currency Translation

Assets and liabilities initially expressed in non-U.S. currencies are translated into U.S. dollars using currency exchange rates determined prior to the close of trading on the New York Stock Exchange, usually at 2:00 p.m. Eastern time. Purchases and sales of securities and income and expenses are translated into U.S. dollars at the prevailing market rates on the dates of such transactions. The effects of changes in non-U.S. currency exchange rates on investment securities and other assets and liabilities are included with the net realized and unrealized gain or loss on investment securities.

Security Transactions

Security transactions are accounted for as of the trade date. Realized gains and losses from security transactions are reported on an identified cost basis for both financial reporting and federal income tax purposes.

For the six months ended June 30, 2006, investment transactions (excluding short-term investments) were as follows:


	Purchases				Proceeds From Sales

	U.S. Gov’t.				U.S. Gov’t.
	Securities		Other		Securities		Other

Core Bond	$	176,772	$	5,880	$	175,921	$	5,662
High Yield		—		80,183		—		88,662
Investment Grade		62,008		86,521		55,888		67,475
Limited Duration		233,152		36,568		232,353		58,165

Repurchase Agreements

The Funds may engage in repurchase agreement transactions. Under the terms of a typical repurchase agreement, a fund takes possession of an underlying debt obligation subject to an obligation of the seller to repurchase, and a fund to resell, the obligation at an agreed-upon price and time, thereby determining the yield during a fund’s holding period. This arrangement results in a fixed rate of return that is not subject to market fluctuations during the fund’s holding period. The value of the collateral is at all times at least equal to the total amount of the repurchase obligation, including interest. In the event of counterparty default, a fund has the right to use the collateral to satisfy the terms of the repurchase agreement. However, there could be potential loss to the fund in the event the fund is delayed or prevented from exercising its right to dispose of the collateral securities, including the risk of a possible decline in the value of the collateral securities during the period in which the fund seeks to assert its rights. The Funds’ investment adviser reviews the value of the collateral and the creditworthiness of those banks and dealers with which the Funds enter into repurchase agreements to evaluate potential risks.

Investment Income and Distributions to Shareholders

Interest income and expenses are recorded on the accrual basis. Bond premiums and discounts are amortized for financial reporting and federal income tax purposes. Dividend income and distributions to shareholders are allocated at the class level and are recorded on the ex-dividend date. Dividends from net investment income are declared daily and paid monthly for each Fund except High Yield, which declares and pays dividends monthly. Net capital gain distributions, which are calculated at the Fund level, are declared and paid after the end of the tax year in which the gain is realized. An additional distribution may be made in December, to the extent necessary in order to comply with federal excise tax regulations. Distributions are determined in accordance with federal income tax regulations, which may differ from those determined in accordance with accounting principles generally accepted in the United States of America; accordingly, periodic reclassifications are made within the Funds’ capital accounts to reflect income and gains available for distribution under federal income tax regulations.

Compensating Balance Credits

The Funds have an arrangement with their custodian bank, whereby a portion of the custodian’s fee is paid indirectly by credits earned on each Fund’s cash on deposit with the bank. This deposit arrangement is an alternative to purchasing overnight investments.

Other

In the normal course of business, the Funds enter into contracts that provide general indemnifications. The Funds’ maximum exposure under these arrangements is dependent upon claims that may be made against the Funds in the future and, therefore, cannot be estimated; however, based on experience, the risk of material loss from such claims is considered remote.

2. Federal Income Taxes:

No provision for federal income or excise taxes is required since each Fund intends to continue to qualify as a regulated investment company and distribute substantially all of its taxable income and capital gain to its shareholders. Because federal income tax regulations differ from accounting principles generally accepted in the United States of America, income and capital gain distributions determined in accordance with tax regulations may differ from net investment income and realized gains recognized for financial reporting purposes. Accordingly, the character of distributions and composition of net assets for tax purposes differ from those reflected in the accompanying financial statements.

3. Financial Instruments:

Options and Futures

As part of their investment programs, the Funds may utilize options and futures. Options may be written (sold) or purchased by the Funds. When a Fund purchases a put or call option, the premium paid is recorded as an investment and its value is marked-to-market daily. When a Fund writes a put or call option, an amount equal to the premium received by the Fund is recorded as a liability and its value is marked-to-market daily.

When options, whether written or purchased, expire, are exercised or are closed (by entering into a closing purchase or sale transaction), the Fund realizes a gain or loss as described in the chart below:


Purchased option:		Impact on the Fund:

The option expires		Realize a loss in the amount of the cost of the option.

The option is closed through a closing sale transaction		Realize a gain or loss depending on whether the proceeds from the closing sale transaction are greater or less than the cost of the option.

The Fund exercises a call option		The cost of the security purchased through the exercise of the option will be increased by the premium originally paid to purchase the option.

The Fund exercises a put option		Realize a gain or loss from the sale of the underlying security. The proceeds of that sale will be reduced by the premium originally paid to purchase the put option.


Written option:		Impact on the Fund:

The option expires		Realize a gain equal to the amount of the premium received.

The option is closed through a closing purchase transaction		Realize a gain or loss without regard to any unrealized gain or loss on the underlying security and eliminate the option liability. The Fund will realize a loss in this transaction if the cost of the closing purchase exceeds the premium received when the option was written.

A written call option is exercised by the option purchaser		Realize a gain or loss from the sale of the underlying security. The proceeds of that sale will be increased by the premium originally received when the option was written.

A written put option is exercised by the option purchaser		The amount of the premium originally received will reduce the cost of the security that the Fund purchased when the option was exercised.

The risk associated with purchasing options is limited to the premium originally paid. Options written by a Fund involve, to varying degrees, risk of loss in excess of the option value reflected in the statement of net assets. The risk in writing a covered call option is that a Fund may forgo the opportunity of profit if the market price of the underlying security increases and the option is exercised. The risk in writing a put option is that a Fund may incur a loss if the market price of the underlying security decreases and the option is exercised. In addition, there is the risk a Fund may not be able to enter into a closing transaction because of an illiquid secondary market or, for over-the-counter options, because of the counterparty’s inability to perform.

Activity in written call and put options during the six months ended June 30, 2006, was as follows:

Core Bond Fund:


	Calls						Puts

	Actual						Actual
	Contracts			Premiums			Contracts			Premiums

Options outstanding at December 31, 2005		104		$	58			68		$	43
Options written		399			184			73			41
Options closed		(54	)		(40	)		(22	)		(15	)
Options expired		(214	)		(114	)		(50	)		(35	)
Options exercised		(5	)		(1	)		(25	)		(12	)

Options outstanding at June 30, 2006		230		$	87			44		$	22

Upon entering into a futures contract, the Fund is required to deposit with the broker cash or cash equivalents in an amount equal to a certain percentage of the contract amount. This is known as the “initial margin.” Subsequent payments (“variation margin”) are made or received by the Fund each day, depending on the daily fluctuation in the value of the contract. The daily changes in contract value are recorded as unrealized gains or losses and the Fund recognizes a realized gain or loss when the contract is closed. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded.

The Funds enter into futures contracts as a hedge against anticipated changes in interest rates. There are several risks in connection with the use of futures contracts as a hedging device. Futures contracts involve, to varying degrees, risk of loss in excess of the amounts reflected in the financial statements. The change in the value of futures contracts primarily corresponds with the value of their underlying instruments, which may not correlate with the change in the value of the hedged instruments. In addition, there is the risk that a Fund may not be able to enter into a closing transaction because of an illiquid secondary market.

Semi-Annual Report to Shareholders 103

The open futures positions and related appreciation or depreciation at June 30, 2006, are listed at the end of each Fund’s portfolio of investments.

Forward Currency Exchange Contracts

As part of its investment program, High Yield may utilize forward currency exchange contracts. The nature and risks of these financial instruments and the reasons for using them are set forth more fully in the Corporation’s prospectus and statement of additional information.

Forward foreign currency contracts are marked-to-market daily using forward foreign currency exchange rates supplied by an independent pricing service. The change in a contract’s market value is recorded by High Yield as an unrealized gain or loss. When the contract is closed or delivery is taken, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations in the underlying prices of the Fund’s securities, but it does establish a rate of exchange that can be achieved in the future. These forward foreign currency contracts involve market risk in excess of amounts reflected in the financial statements. Although forward foreign currency contracts used for hedging purposes limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase. In addition, the Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. The Fund’s adviser will enter into forward foreign currency contracts only with parties approved by the Board of Directors because there is a risk of loss to the Fund if the counterparties do not complete the transaction.

At June 30, 2006, High Yield had no open forward currency exchange contracts.

Swap Agreements

The use of swaps involves risks that are different from those associated with ordinary portfolio securities transactions. Swap agreements may be considered to be illiquid. Although a Fund will not enter into any swap agreement unless the adviser believes that the other party to the transaction is creditworthy, a Fund does bear the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of the agreement counterparty. The nature and risks of these financial instruments and the reasons for using them are set forth more fully in the Corporation’s prospectus and statement of additional information.

The Funds may invest in different types of swap agreements. Credit default swap contracts represent the exchange of commitments to provide a level of credit protection for a commitment to receive interest at a fixed rate based on the potential risk of default of the relevant underlying issuer. Interest rate swap contracts involve the exchange of commitments to pay and receive interest based on a notional principal amount. Total return swap contracts involve the exchange of commitments to pay and receive interest based on the total return of an index over a specified period.

At June 30, 2006, there were no swap contracts outstanding for any fund.

4. Transactions With Affiliates:

Each Fund has a management agreement with Legg Mason Fund Adviser, Inc. (“LMFA”). Pursuant to their respective agreements, LMFA provides the Funds with management and administrative services for which each Fund pays a fee, computed daily and payable monthly, at annual rates of each Fund’s average daily net assets. LMFA has contractually agreed to waive its fees to the extent Core Bond and Limited Duration’s expenses (exclusive of taxes, interest, brokerage and extraordinary expenses) exceed during any month certain annual rates. These contractual expense limitations are due to expire on April 30, 2007. LMFA has voluntarily agreed to waive fees to the extent that Investment Grade’s expense (exclusive of taxes, interest, brokerage and extraordinary expenses) exceed during any month certain annual rates. This voluntary waiver is currently expected to continue until April 30, 2007, but may be terminated at any time. Pursuant to an agreement approved by the Board, each Fund has agreed to repay LMFA for waived fees and reimbursed expenses provided that payment does not cause operating expenses to exceed 1.00% of the Primary Class’s average net assets and 0.50% of the Institutional Class’s average net assets and the payment is made within three years after the year in which LMFA earned the fee or incurred the expense. At June 30, 2006, High Yield has no expense

Western Asset Management Company (“Adviser”) serves as investment adviser to the Funds. The Adviser is responsible for the actual investment activity of each Fund. LMFA pays the Adviser a fee, computed daily and payable monthly, at an annual rate of 40% of the management fee received by LMFA for Core Bond; 77% of the management fee received by LMFA for High Yield; 40% of the management fee received for Investment Grade. For Limited Duration, LMFA pays the Adviser a fee, computed daily and payable monthly, of 0.20% of its average daily net assets, not to exceed the fee received by LMFA.

Legg Mason Investor Services, LLC (“LMIS”) serves as distributor of the Funds. LMIS receives an annual distribution fee and an annual service fee based on each Fund’s Primary Class’s average daily net assets, computed daily and payable monthly as shown in the table below. For the six months ended June 30, 2006, LMIS waived $166 and $71 of the distribution and service fees for Investment Grade and Limited Duration, respectively.

For this assistance, the transfer agent paid LMFS the following amounts during the six months ended June 30, 2006: Core Bond, $9; High Yield, $21; Investment Grade, $36; and Limited Duration, $22.

LMFA, the Adviser, LMIS and LMFS are corporate affiliates and wholly owned subsidiaries of Legg Mason, Inc.

Under a Deferred Compensation Plan (“Plan”), directors may elect to defer receipt of all or a specified portion of their compensation. A participating director may select one or more funds in which his or her deferred director’s fees will be deemed to be invested. Deferred amounts remain in the fund until distributed in accordance with the Plan.

5. Line of Credit:

The Funds, along with certain other Legg Mason Funds, participate in a $400 million line of credit (“Credit Agreement”) to be used for temporary or emergency purposes. Pursuant to the Credit Agreement, each participating Fund is liable only for principal and interest payments related to borrowings made by that Fund. Borrowings under the Credit Agreement bear interest at a rate equal to the federal funds rate plus the federal funds rate margin. For the six months ended June 30, 2006, the Funds had no borrowings under the credit agreement.

6. Fund Share Transactions:

Information regarding how each Fund voted proxies relating to portfolio securities during the most recent twelve-month period ended June 30 is also available on the SEC’s website or through the Legg Mason Funds’ website at www.leggmasonfunds.com/about.
