To Our Shareholders,

   We are pleased to provide you with Legg Mason Income Trust’s annual report for the year ended December 31, 2005, combining reports for the Legg Mason Core Bond Fund, High Yield Portfolio, Investment Grade Income Portfolio, Limited Duration Bond Portfolio and the U.S. Government Money Market Portfolio.

   The following table summarizes key statistics for the Primary Class of each portfolio, as of December 31, 2005:

					Net Asset Value
	SEC YieldA		Average Life		Per Share
Core Bond		4.07%		8.42 years	$	9.71
High Yield		6.61%		6.94 years	$	8.93
Investment Grade		5.00%		10.31 years	$	10.40
Limited DurationB		3.89%		3.32 years	$	10.20
U.S. Government Money MarketC		3.55%		49 days	$	1.00

   For the year ended December 31, 2005, total returns for the Primary Class of shares of the Core Bond, High Yield, Investment Grade and Limited Duration Portfolios were +0.94%, +2.39%, +1.69%, and +1.83%, respectively. Total returns for the Institutional Class of shares of High Yield, Investment Grade and Limited Duration Portfolios were +2.94%, +2.27%, and +2.29%, 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. The U.S. Government Money Market Portfolio seeks to preserve the value of your investment at $1.00 per share; however, it is possible to lose money by investing in the Fund. The U.S. Government Money Market Portfolio is primarily invested in government agency securities. Although most government agency securities are not backed by the full faith and credit of the U.S. government, all such securities held in the Portfolio at December 31, 2005 carry the highest quality ratings of the Standard & Poor’s and Moody’s rating services.

   PricewaterhouseCoopers LLP, the Funds’ independent registered public accounting firm, has completed its annual audit examination, and audited financial statements for the fiscal year ended December 31, 2005, are included in this report.

^A  SEC yields reported for the Core Bond, High Yield, Investment Grade and Limited Duration Portfolios are for the 30 days ended December 31, 2005. For the U.S. Government Money Market Portfolio, the SEC yield is for the 7 days ended December 31, 2005.

^B  Limited Duration was formerly the U.S. Government Intermediate Portfolio, see page 85 for additional information about the change.

^C  An investment in the U.S. Government Money Market Portfolio is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

   On January 3, 2006, the Board of Directors of the Legg Mason U.S. Government Money Market Portfolio approved, subject to shareholder approval, a Plan of Liquidation, Dissolution and Termination whereby all the Fund’s assets would be liquidated and the Fund would subsequently be dissolved. The estimated time of liquidation is February 27, 2006.

   Many of our shareholders regularly add to their Primary Class Fund holdings by authorizing automatic, monthly transfers from their bank checking or brokerage accounts. Your financial adviser will be happy to help you establish a dollar cost averaging plan should you wish to do so.

   Finally, we wanted to update you on previously announced news regarding Legg Mason. We recently completed a business transaction with Citigroup that enabled us to become one of the top five mutual fund companies in the United States.^D As of December 31, 2005, Legg Mason, Inc.’s assets under management totalled $850.8 billion. Of that amount, $362.6 billion were in mutual funds advised by the investment advisory affiliates of Legg Mason, Inc. On page 3 you will find a letter from Raymond A. “Chip” Mason, Legg Mason’s chairman and chief executive officer, describing the significance of this transaction and our deep commitment to the clients of all of our asset management businesses.

Sincerely,

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

To Our Clients and Shareholders Worldwide,

   Today represents a major milestone in the proud, over a century history of Legg Mason. With the successful acquisition of Citigroup’s worldwide asset management business, Legg Mason has transformed itself from a well-regarded money management and regional securities firm into a global asset manager with more than $800 billion in assets under management. We undertook this important step to enable us to concentrate all of our resources on what we believe we do best: managing your money.

   While we understand some things will change, there are two core beliefs that you can continue to count on from us. First, we believe that the bedrock of any successful organization is its character and integrity. Second, we are deeply committed to encouraging and supporting the many talented money managers throughout the Legg Mason organization in their quest to be both independent and performance driven. All of our managers share a common organizational mission: “To be one of the best money managers in the world.”

   As a global money manager, we now offer institutions, mutual fund and high net worth individual investors around the world a constellation of sophisticated money management services from which to choose—from equity to alternative to fixed income products offered throughout the United States, United Kingdom, Europe, Japan, Hong Kong, Australia, Singapore, Latin America and Canada.

   So, whether you are a satisfied client of Legg Mason Capital Management, Western Asset Management, Private Capital Management, Royce, Brandywine, Batterymarch, Permal or any of the many former Citigroup mutual funds or separate accounts that now comprise the ‘new’ Legg Mason, you should know that we pledge to you that we will work hard to meet your investment objectives, every day.

Sincerely,

/s/ Raymond A. Mason

Management’s Discussion of Fund Performance

Core Bond Fund

   The average annual total return for the Core Bond Fund for the period from its inception to December 31, 2005, is presented below, along with the total return of its benchmark:

				Since
		One Year		InceptionA
Core Bond Fund
	Primary Class		+0.94%		+1.54%
Lehman Aggregate Bond IndexB			+2.43%		+4.88%

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 period.

   Our investment strategy produced generally negative results. The total return (appreciation or depreciation in the Fund’s net asset value per share, plus dividends and any capital gain distributions) of the Fund’s Primary Class lagged the performance of its primary benchmark, the Lehman Aggregate Bond Index, delivering 0.94% versus 2.43% for the index. The Fund’s underweight duration stance suffered as yields fell, but its barbelled exposure to maturities benefited from a flatter yield curve. A neutral-to-underweight exposure to the credit sector was rewarded as spreads widened, but an emphasis on BBB-rated bonds suffered since they underperformed higher-quality bonds. An overweight exposure to Treasury Inflation-Protected Securities^C subtracted modestly from performance as they underperformed Treasuries.

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 July 1, 2005, and held through December 31, 2005.

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.

	Beginning		Ending		Expenses PaidA
	Account		Account		During the
	Value		Value		Period
	7/1/05		12/31/05		7/1/05 to 12/31/05
Actual	$	1,000.00	$	992.60	$	5.02
Hypothetical (5% return before expenses)		1,000.00		1,020.16		5.09

^A  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 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 (184), 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.

Management’s Discussion of Fund Performance

High Yield Portfolio

   Average annual total returns for the High Yield Portfolio (“Fund”) and its benchmark for various periods ended December 31, 2005, are presented below:

		One		Five		Ten		Since
		Year		Years		Years		InceptionA
High Yield
	Primary Class		+2.39%		+5.66%		+4.59%		+5.03%
	Institutional Class		+2.94%		+6.06%		N/A		+1.77%
Lehman High Yield Index 2% Issuer ConstrainedB			+2.76%		+9.12%		+6.70%		+6.87%
Lehman High Yield IndexC			+2.74%		+8.85%		+6.54%		+6.74%

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 for the Primary Class please visit www.leggmasonfunds.com; for the Institutional Class please call 1-888-425-6432. 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.

   For the calendar year 2005 the Primary Class of the Fund returned 2.39% versus 2.76% for the Fund’s primary benchmark, the Lehman High Yield Index 2% Issuer Constrained. Effective September 1, 2005, the Fund changed its comparative index from the Lehman High Yield Index to the Lehman High Yield Index 2% Issuer Constrained (“High Yield Constrained Index”). As a result of significant changes to the Lehman High Yield composition and Lehman index methodology rules, the adviser has determined that the High Yield Constrained Index is more representative of the overall high yield market and therefore, more accurately reflects the types of securities in which the fund invests. The option-adjusted-spread (“OAS”)^D of the index widened from +288 basis points (“bps”)^E on 12/31/04, to +336 bps on 12/31/05. A significant part of the spread widening is attributable

^A The inception date of the Primary Class is February 1, 1994. The inception date of the Institutional Class is May 5, 1998. Index returns are for periods beginning January 31, 1994.

^B A market value-weighted index that tracks the daily price, coupon, and total return performance of non-investment grade, fixed rate, publicly placed, dollar-denominated, and non-convertible debt registered with the U.S. Securities and Exchange Commission. The index limits the maximum exposure to any one issuer to 2%.

^C A market value-weighted index that tracks the daily price, coupon, and total return performance of non-investment grade, fixed rate, publicly placed, dollar-denominated, and non-convertible debt registered with the U.S. Securities and Exchange Commission.

^D This is a measuring tool for evaluating price differences between similar products with different embedded options. A larger OAS implies a greater return for greater risks.

to the inclusion of the autos into the high yield index in the second half of the year as opposed to an actual widening of the issues that were in the index for the entire year.

   The Fund’s underperformance is attributable to the adviser’s decision to overweight the lower quality spectrum of the high yield market. The CCC and lower rated issues in the index returned 0.89%. Consistent with the adviser’s overall strategy the portfolio maintained a short duration position, which had minimal impact on performance as short rates rose and long rates declined.

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 July 1, 2005, and held through December 31, 2005.

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 PaidA
		Account		Account		During the
		Value		Value		Period
		7/1/05		12/31/05		7/1/05 to 12/31/05
Primary Class:
	Actual	$	1,000.00	$	1,019.70	$	7.11
	Hypothetical (5% return before expenses)		1,000.00		1,018.16		7.11
Institutional Class:
	Actual	$	1,000.00	$	1,022.40	$	4.29
	Hypothetical (5% return before expenses)		1,000.00		1,020.96		4.29

^A  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 1.40% and 0.84% for the Primary Class and Institutional Class, respectively, multiplied by the average value over the period, multiplied by the number of days in the most recent fiscal half-year (184), and divided by 365.

Performance Information

High Yield 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 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.

   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.

Management’s Discussion of Fund Performance

Investment Grade Income Portfolio

   Average annual total returns for the Investment Grade Income Portfolio (“Fund”) and its benchmark for various periods ended December 31, 2005, are presented below:

		One		Five		Ten		Since
		Year		Years		Years		InceptionA
Investment Grade
	Primary Class		+1.69%		+6.86%		+6.37%		+7.61%
	Institutional Class		+2.27%		+7.43%		+6.95%		+6.98%
Lehman Credit Bond IndexB			+1.96%		+7.12%		+6.46%		+8.31%
Lehman Aggregate Bond IndexC			+2.43%		+5.87%		+6.16%		+7.77%

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 for the Primary Class please visit www.leggmasonfunds.com; for the Institutional Class please call 1-888-425-6432. 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.

   For the calendar year 2005 the Primary Class of the Fund returned 1.69% versus 1.96% for its primary benchmark, the Lehman Credit Bond Index. The option-adjusted-spread (“OAS”)^D of the index widened from +75 basis points (“bps”)^E to similar duration treasuries on 12/31/04, to +83 bps on 12/31/05. The asset class underperformed similar duration Treasuries in large part due to the poor performance of the auto sector. The Fund’s underperformance is primarily attributable to the adviser’s decision to overweight the consumer cyclical sub-sector (inclusive of the auto companies) which returned -4.71% for the period. Being overweight to the utility sector, which returned 3.02% and having

^A The inception date of the Primary Class is August 7, 1987. The inception date of the Institutional Class is December 1, 1995. Index returns are for periods beginning July 31, 1987.

It also includes Yankee bonds, which are dollar- denominated, SEC-registered public, non-convertible debt issued or guaranteed by foreign sovereign governments, municipalities, governmental agencies, and international agencies.

^C 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 non- convertible investment grade debt issues with at least $100 million par amount outstanding and with at least one year to final maturity.

exposure to U.S. Treasury securities helped relative performance. Consistent with the adviser’s overall strategy, the Fund maintained a short duration position which had minimal impact on performance as short rates rose and long rates declined.

Expense Example

Investment Grade Income 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 July 1, 2005, and held through December 31, 2005.

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 PaidA
		Account		Account		During the
		Value		Value		Period
		7/1/05		12/31/05		7/1/05 to 12/31/05
Primary Class:
	Actual	$	1,000.00	$	994.00	$	5.03
	Hypothetical (5% return before expenses)		1,000.00		1,020.16		5.09
Institutional Class:
	Actual	$	1,000.00	$	997.80	$	2.22
	Hypothetical (5% return before expenses)		1,000.00		1,022.68		2.24

^A  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 1.00% and 0.44% for the Primary Class and Institutional Class, respectively, multiplied by the average value over the period, multiplied by the number of days in the most recent fiscal half-year (184), and divided by 365.

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.

   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.

Management’s Discussion of Fund Performance

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 for the Primary Class please visit www.leggmasonfunds.com; for the Institutional Class please call 1-888-425-6432. 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.

   Our investment strategies were generally rewarded as the Fund’s total return (appreciation or depreciation in the Fund’s net asset value per share, plus dividends and any capital gain distributions) of the various share classes exceeded the performance of its primary benchmark, the Merrill Lynch 1-3 Year Treasury Index. For the calendar year, the Fund’s Primary Class returned 1.83% versus the benchmark’s return of 1.67%. The Fund’s modestly underweight duration posture for most of the period contributed to performance, since interest rates rose by more than the market had expected, and the Fund’s barbelled exposure to maturities for most of the period was rewarded by a flatter yield curve. Overweight exposure to short- and intermediate-maturity mortgage-backed securities and

^A  The inception date of the Primary Class is August 7, 1987. The inception date of the Institutional Class is December 1, 1994. Index returns are for periods beginning July 31, 1987.

^B  Prior to August 31, 2004, the Fund was known as 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.

^C  Effective June 30, 2004, Limited Duration changed its comparative index from the Lehman Intermediate Government Bond Index to the Merrill Lynch 1-3 year Treasury Index, because the new index is more representative of the types of securities in which the Fund invests.

^D  A total rate of return index based on daily closing prices and consisting of Treasury bills with a maturity of 1 to 3 years.

^E  The total return index consisting of investment grade corporate debt issues as well as U.S. government securities. The debt issues all maintain maturities within a range of 1 to 10 years.

asset-backed securities contributed substantially to performance, as their higher yields and relatively stable spreads resulted in excess returns relative to Treasuries. A modest exposure to BBB-rated corporate bonds detracted somewhat from performance, however, as spreads generally widened.

Expense Example

Limited Duration Bond 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 July 1, 2005, and held through December 31, 2005.

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 PaidA
		Account		Account		During the
		Value		Value		Period
		7/1/05		12/31/05		7/1/05 to 12/31/05
Primary Class:
	Actual	$	1,000.00	$	1,008.40	$	5.06
	Hypothetical (5% return before expenses)		1,000.00		1,020.16		5.09
Institutional Class:
	Actual	$	1,000.00	$	1,010.10	$	2.33
	Hypothetical (5% return before expenses)		1,000.00		1,022.68		2.35

^A  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 1.00% and 0.46% for the Primary Class and Institutional, Class respectively, multiplied by the average value over the period, multiplied by the number of days in the most recent fiscal half-year (184), and divided by 365.

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.

   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.

   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.

Expense Example

U.S. Government Money Market Portfolio

   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 July 1, 2005, and held through December 31, 2005.

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.

	Beginning		Ending		Expenses PaidA
	Account		Account		During the
	Value		Value		Period
	7/1/05		12/31/05		7/1/05 to 12/31/05
Actual	$	1,000.00	$	1,014.80	$	3.66
Hypothetical (5% return before expenses)		1,000.00	$	1,021.58	$	3.67

^A  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 ratio of 0.72% multiplied by the average value over the period, multiplied by the number of days in the most recent fiscal half-year (184), and divided by 365.

Notes to Financial Statements

Legg Mason Income Trust, Inc.

(Amounts in Thousands)

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”), the Limited Duration Bond Portfolio, (“Limited Duration”), and the U.S. Government Money Market Portfolio (“Government Money Market”) (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 Core Bond, High Yield, Investment Grade and Limited Duration 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.

   In accordance with Rule 2a-7, the investments of Government Money Market are valued on the basis of amortized cost, so long as the Fund’s Board of Directors determines that this method constitutes fair value. Under this method, securities are valued at cost when purchased and, thereafter, a constant proportionate accretion or amortization of any discount or premium is recorded until maturity of the security.

Legg Mason Income Trust, Inc. — Continued

Annual Report to Shareholders

114

   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.

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 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 recorded on the next business day after 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 year ended December 31, 2005, investment transactions (excluding short-term investments) were as follows:

	Purchases				Proceeds From Sales
	U.S. Gov’t.				U.S. Gov’t.

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.

   Distribution during the years ended December 31, 2005 and 2004, were characterized as follows for tax purposes:

	Core Bond				High Yield				Investment Grade
	2005		2004		2005		2004		2005		2004
Ordinary income	$	2,410	$	1,183	$	14,058	$	14,760	$	19,613	$	19,210
Long-term capital gains		—		—		—		—		2,957		8,438
Total Distribution	$	2,410	$	1,183	$	14,058	$	14,760	$	22,570	$	27,648

	Limited				Government

Long-term capital gains		—		—		—		—
Total Distribution	$	9,089	$	11,006	$	9,501	$	2,864

   Pursuant to federal income tax regulations applicable to investment companies, the Funds have elected to treat net capital losses realized between November 1 and December 31 of each year (“post-October loss”) as occurring on the first day of the following tax year. For the year ended December 31, 2005, realized capital losses reflected in the accompanying

Annual Report to Shareholders

117

financial statements, as shown in the table on the next page, will not be recognized for federal income tax purposes until 2006.

   The tax basis components of net assets at December 31, 2005, were:

	Core			High			Investment			Limited			Government
	Bond			Yield			Grade			Duration			Money Market
Unrealized appreciation	$	796		$	3,430		$	10,928		$	442		$	—

Net assets	$	71,825		$	169,788		$	386,770		$	237,710		$	406,408

   The Funds intend to retain realized capital gains that may be offset against available capital loss carryforwards for federal income tax purposes. At December 31, 2005, the Funds had capital loss carryforwards as follows:

Expiration					High			Limited
Date		Core Bond			Yield			Duration
	2008	$	—		$	(35,788	)	$	(3,833	)
	2009		—			(83,723	)		—

	2012		—			—			(4,536	)
	2013		(582	)		(84	)		(555	)

   At December 31, 2003, there were no capital loss carryforwards for Government Money Market and Investment Grade.

   For financial reporting purposes, capital accounts and distributions to shareholders are adjusted to reflect the tax character of permanent book/tax differences. For the year ended December 31, 2005, the Funds recorded the following permanent reclassifications, which

Notes to Financial Statements — Continued

Annual Report to Shareholders

relate primarily to reclassifications of gains/losses on paydown, securities and swap securities and distribution in excess. Results of operations and net assets were not affected by these reclassifications.

	Core			High			Investment			Limited			Government
	Bond			Yield			Grade			Duration			Money Market
Undistributed net investment income	$	67		$	34		$	1		$	391		$	—
Accumulated realized gain/(loss)		(67	)		36			(1	)		(376	)		—
Paid-in capital		—			(70	)		—			(15	)		—

   At December 31, 2005, the cost of investments for federal income tax purposes was $94,037 for Core Bond, $167,936 for High Yield, $380,125 for Investment Grade, $259,319 for Limited Durations, and $387,258 for Government Money Market.

3. Financial Instruments:

Options and Futures

   As part of their investment programs, Core Bond, High Yield, Investment Grade and Limited Duration may utilize options and futures. Options may be written (sold) or purchased by these 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.

Annual Report to Shareholders

119

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 year ended December 31, 2005, was as follows:

Core Bond Fund:

	Calls						Puts
	Actual						Actual
	Contracts			Premiums			Contracts			Premiums
Options outstanding at December 31, 2004		76		$	57			105		$	97
Options written		600,587			393			527			364
Options closed		(218	)		(154	)		(293	)		(223	)
Options expired		(600,296	)		(216	)		(236	)		(173	)
Options exercised		(45	)		(22	)		(35	)		(22	)
Options outstanding at December 31, 2005		104		$	58			68		$	43

   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.

   The open futures positions and related appreciation or depreciation at December 31, 2005, for Core Bond, Investment Grade, and Limited Duration 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

Annual Report to Shareholders

121

because there is a risk of loss to the Fund if the counterparties do not complete the transaction.

   At December 31, 2005, 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 December 31, 2005, 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 each Fund’s expenses (exclusive of taxes, interest, brokerage and extraordinary expenses) exceed during any month certain annual rates. These contractual expense limitations for Core Bond, Investment Grade and Limited Duration are due to expire on April 30, 2006. 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. LMFA has also contractually agreed to waive its fees (and to the extent necessary, bear other expenses) from December 1, 2005 through December 31, 2006, to the extent that expenses of Government Money Market (exclusive of interest, taxes, brokerage commissions, and extraordinary expenses) exceed an annual rate of 0.72%. At December 31, 2005, High Yield has no expense limitation. The following chart shows

   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; and 30% for Government Money Market. 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.

   On December 1, 2005, Legg Mason Investor Services, LLC (“LMIS”) replaced Legg Mason Wood Walker, Inc. (“Legg Mason”) as Distributor. The compensation arrangements between the Funds and LMIS are identical to the previous arrangements between the Funds and Legg Mason. 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 year ended December 31, 2005, Legg Mason waived $29 of the Core Bond’s distribution and service fees.

   LM Fund Services, Inc. (“LMFS”), a registered transfer agent, has an agreement with the Funds’ transfer agent to assist it with some of its duties. For this assistance, the transfer agent paid LMFS the following amounts during the year ended December 31, 2005: Core Bond, $18; High Yield, $51; Investment Grade, $80; Limited Duration, $51; and Government Money Market, $83.

   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, excluding Government Money Market, but including 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 year ended December 31, 2005, the Funds had no borrowings under the credit agreement.

6. Fund Share Transactions:

   At December 31, 2005, there were 2,000,000 shares authorized at $.001 par value for all classes of each portfolio of the Corporation. At December 31, 2005, for U.S. Government Money Market, net assets consisted of paid-in capital of $406,408 and accumulated net realized gain of $1. Share transactions for the Funds were as follows:

Report of Independent Registered Public Accounting Firm

To the Shareholders of Core Bond Fund, High Yield Portfolio, Investment Grade Income Portfolio, Limited Duration Bond Portfolio, and U.S. Government Money Market Portfolio, and to the Directors of Legg Mason Income Trust, Inc.:

   In our opinion, the accompanying statements of assets and liabilities for Core Bond Fund, High Yield Portfolio, Investment Grade Income Portfolio, and Limited Duration Bond Portfolio, including the portfolio of investments, and the statement of net assets for U.S. Government Money Market Portfolio, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Core Bond Fund, High Yield Portfolio, Investment Grade Income Portfolio, Limited Duration Bond Portfolio, and U.S. Government Money Market Portfolio (comprising Legg Mason Income Trust, Inc., hereafter referred to as the “Funds”) at December 31, 2005, the results of each of their operations, the changes in each of their net assets and the financial highlights for each of the fiscal periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

   As explained in Note 7, the Board of Directors of U.S. Government Money Market Portfolio approved, subject to shareholder approval, a Plan of Liquidation, Dissolution and Termination whereby all the U.S. Government Money Market Portfolio’s assets would be liquidated and U.S. Government Money Market Portfolio would subsequently be dissolved.

Board Consideration of Legg Mason Income Trust’s Investment Advisory Agreement and Management Agreement

   At its November 2005 meeting, the Board of Directors, including all of the Independent Directors, approved the continuation of the Management Agreements between Legg Mason Fund Adviser, Inc. (the “Manager”) and Income Trust on behalf of each of its separate series and the Investment Advisory Agreements between the Manager and Western Asset Management Company (the “Adviser”) for each separate series of Income Trust (each an “Agreement”). In voting to approve the continuation of each Agreement, the Board considered whether continuance would be in the best interests of each series of Income Trust and its shareholders, an evaluation largely based on the nature and quality of the services provided under each Agreement and the overall fairness of each Agreement to each series of Income Trust. In considering each Agreement, the Board did not identify any single factor or item of information as all-important or controlling. Based on its evaluation of all material factors, including those described below, the Board concluded that the terms of each Agreement are reasonable and fair and that the continuation of each Agreement is in the best interests of each series of Income Trust and its shareholders.

   Prior to the Board action, the Independent Directors met as a committee to consider its recommendation as to continuance of each Agreement. As part of the process to consider each Agreement, legal counsel to Income Trust requested certain information from the Manager and the Adviser on behalf of the Independent Directors, and in response, the Manager and the Adviser provided extensive reports that addressed specific factors designed to inform the Board’s consideration of each Agreement. Counsel also provided the Independent Directors and the Board with a memorandum detailing their responsibilities pertaining to the continuance of each Agreement.

   In addition to the November meeting, the Independent Directors meeting as a committee held additional meetings in September and October 2005 at which materials relating to each Agreement were reviewed and analyzed. The Independent Directors also retained an independent consultant to assist them in their review and analysis of each Agreement. The Board meets at least another three times per year in order to oversee the Legg Mason Funds, including meetings at which the portfolio managers of each series of Income Trust or others submit or make presentations and discuss performance, compliance and other applicable issues. The Board also drew upon its long association with the Manager, the Adviser and their personnel, and the Board members’ familiarity with their culture, and the manner in which they have sought to strengthen and enhance themselves.

   With respect to the nature, scope and quality of the services provided, the Board considered the experience and commitment of the Manager’s and the Adviser’s personnel and their efforts to build and support a strong service team. The Board also considered the nature and quality of the Adviser’s investment process. In assessing performance, the Board compared the returns of each series of Income Trust to the average of an appropriate Lipper category and a peer group of investment companies pursuing similar strategies, all over

multiple time periods. The Board also considered the performance of each series of Income Trust in the context of the risk undertaken by the portfolio manager. The Board noted the performance record of each series of Income Trust and the measures that the Manager and the Adviser were taking in an effort to maintain or achieve attractive long-term performance. The Board also considered the level of service provided by the Manager to Income Trust, including oversight of the transfer agent, the custodian, fund legal counsel, and investment adviser and fund compliance, and preparation of regulatory filings. The Board considered the Adviser’s procedures for executing portfolio transactions for each series of Income Trust. The Board also reviewed the Adviser’s report on its policies and procedures for the selection of brokers and dealers.

   In determining whether the terms of each Agreement are reasonable and fair, the Board considered the terms and fee structure of each Agreement. In that connection, the Board considered the costs to the Manager and the Adviser in providing services to each series of Income Trust and profitability for the Manager and its affiliates from their overall association with each series of Income Trust. The Board reviewed information about the advisory fee schedule and overall expense ratio of each series of Income Trust and comparable fee schedules and expense ratios of a peer group of funds. Although Limited Duration Bond Portfolio, Investment Grade Income Portfolio, High Yield Portfolio and Core Bond Fund had not yet grown to a size where any potential economies of scale might become apparent, the Board satisfied itself that the fees paid by each of these series at its current asset level are appropriate and noted the Manager’s agreement to waive fees for Limited Duration Bond Portfolio, Investment Grade Income Portfolio and Core Bond Fund. In considering whether any economies of scale experienced by the Manager and the Adviser in providing services to U.S. Government Money Market Portfolio were shared with that series, the Board further noted that the advisory fee structure for that series provides for a reduction of the effective fee rate as asset levels increase. The Board also compared the advisory fee schedule for each series of Income Trust to the advisory fees charged by the Adviser to its other accounts managed in a similar style. In that connection, the Board considered the differences in the level of services provided and the differences in responsibility of the Adviser to each series of Income Trust and to the other accounts. Finally, the Board considered the benefits accruing to the Manager, the Adviser and their affiliates by virtue of their relationship to each series of Income Trust.

Tax-Free Intermediate-Term Income Trust Legg Mason, Inc., based in Baltimore, Maryland, has built its reputation, at least in part, on the success of the Legg Mason Funds, introduced in 1979. The primary purpose of our funds is to enable investors to diversify their portfolios across various asset classes and, consequently, enjoy the stability and growth prospects generally associated with diversification.

The success of our funds is contingent on the experience, discipline, and acumen of our fund managers. We believe the quality of our managers is crucial to investment success. Unlike many firms, which focus on a particular asset class or the fluctuations of the market, at Legg Mason we focus on providing a collection of top-notch managers in all the major asset classes.

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.

Each Fund files its complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. You may obtain a free copy of each Fund’s portfolio holdings as filed on Form N-Q, by contacting each Fund at the appropriate phone number, address or website listed below. Additionally, each Fund’s Form N-Q is available on the SEC’s website (http://www.sec.gov) or may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. Information about the operation of the Public Reference Room may be obtained by calling 1-800-SEC-0330.
