Report of Independent Registered Public Accounting Firm



To the Trustees of The Legg Mason Profit Sharing and 401 (k) Plan and Trust:


In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of The Legg Mason Profit Sharing and 401 (k) Plan and Trust (the “Plan”) at December 31, 2005 and 2004, and the changes in net assets available for benefits for the year ended December 31, 2005  in conformity with accounting principles generally accepted in the United States of America.  These financial statements are the responsibility of the Plan’s management.  Our responsibility is to express an opinion on these financial statements based on our audits.  We conducted our audits of these 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 provide a reasonable basis for our opinion.


Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole.  The supplemental schedule of assets (held at end of year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.  This supplemental schedule is the responsibility of the Plan's management.  The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Description of Plan


The following description of the Legg Mason Profit Sharing and 401(k) Plan and Trust (the “Plan”) provides only general information.  Participants should refer to the plan agreement for a more complete description of the Plan’s provisions.  


General

The Plan is a defined contribution plan which covers substantially all employees of Legg Mason & Co., LLC ("LM & Co"), and affiliated participating companies (the “Company”) and is subject to the provisions of the Employee Retirement Income Security Act (“ERISA”).  An employee becomes eligible to participate in the Plan on their date of hire.  A participant shares in employer contributions and forfeitures by completing 1,000 hours of service, as defined by the Plan, in a Plan year and being employed on the last day of the Plan year.  


Contributions

Contributions by employees are voluntary and may be composed of all or any of the following:


A.

A rollover of accumulated deductible employee contributions as contemplated by Section 408(d)(3) of the Internal Revenue Code.


B.

A voluntary compensation deferral whereby the participant may elect to defer, in the form of Company contributions to the Plan on the participant’s behalf, compensation that would otherwise have been paid to the participant during the Plan year.  This compensation deferral, if elected, cannot be less than 1% nor more than 50% of the compensation that would otherwise have been paid to the participant during the Plan year.  


The Company will contribute a matching contribution to all eligible employees equal to 50% of the employee’s contribution up to 6% of such employee’s annual earnings up to a maximum of $3,000 per employee annually.  Additionally, the Company may make discretionary profit sharing contributions to the Plan.  See Note 3 for further disclosure.


Participant Accounts

Each participant’s account is credited with the participant’s contributions and an allocation of (a) the Company’s contributions, (b) Plan earnings/losses, and (c) forfeitures of terminated participants’ non-vested accounts.  Allocations are based on participant earnings or account balances, as defined.  The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Notes to Financial Statements

December 31, 2005 and 2004



Vesting

Participants are immediately vested in voluntary contributions, rollover contributions, and income earned thereon.  Participants will immediately vest in the Company’s matching contribution only if they are eligible to receive one.  Vesting in the Company’s discretionary profit sharing contributions are based on years of continuous service as presented in the following chart:



Years of Service

Percentage Vested

  

less than 2

0%

2

25%

3

50%

4

75%

5

100%


A participant’s account becomes 100% vested in the profit sharing contribution, regardless of years of service, at age 65 or in the event of permanent disability or death.


Payment of Benefits

Upon an employee’s withdrawal from the Plan or a break in service of more than five years, any non-vested portion of a participant’s account is forfeited and is reallocated to participants’ accounts in the same proportion as the Company’s contribution to the Plan attributable to the Plan year in which the forfeitures occurred.


Participants are entitled to a benefit equal to the vested portion of their account which will be distributed in the form of a lump sum payment unless the participant elects another option as provided by the Plan.


Loans to Participants

Participants are eligible to obtain loans from the Plan. Participants can borrow up to 50% of their vested account balance, but not more than $50,000 less the highest outstanding loan balance during the preceding twelve months. Loan repayment periods range from one to twenty-four years.  The loans accrue interest at a rate commensurate with prevailing rates as determined by the Plan.  As of December 31, 2005, interest rates on these loans ranged from 4.0% to 10.5%.  The Company has the authority to deny plan loans to any director or executive officer to the extent necessary to conform to the Sarbanes Oxley Act of 2002.  The Company has the right to discontinue the policy of extending loans to participants, however, it may not affect the terms or provisions of any loans outstanding at that time.


Administrative Expenses

The Company pays all of the administration and operations expenses of the Plan.


Plan Changes

On January 1, 2005, the plan changed record keepers to The 401(k) Company.   Participants could not make any changes to their account balances through January 18, 2005.


On December 1, 2005, Legg Mason, Inc. completed the sale of its subsidiary, Legg Mason Wood Walker, Inc.  As a result, the Plan Sponsor was changed to LM & Co.

Significant Accounting Policies


A.  Basis of Accounting

The financial statements of the Plan are prepared on the accrual basis of accounting.  


B.

Investments Valuation and Income Recognition

Plan investments are stated at fair value.  Shares of registered investment companies are reported at their stated net asset value per share and shares of common stock are valued at quoted market prices.  Unit values of the common stock fund are based on the quoted market price of common stock held by the fund, along with cash equivalents.  Participant loans are valued at cost plus accrued interest, which approximates fair value.  Purchases and sales of securities are reflected on a trade date basis.  


Dividend income is recorded on the ex-dividend date.  Dividends earned from mutual fund investments and the Legg Mason Common Stock Fund are reinvested into additional shares of those funds.  Dividends earned from Legg Mason stock are reallocated to other funds based on current investment elections.  Interest income is accrued as earned.


The Plan presents, in the statement of changes in net assets available for plan benefits, the net appreciation in the fair value of its investments, which consists of realized gains and losses, and the change in the unrealized appreciation or depreciation of those investments during the Plan year.


C.

Contribution

Employee contributions are recorded in the period during which the Company makes payroll deductions from the Plan participants’ earnings.  Company contributions are made annually and recorded in the period to which it relates.


D.

Payment of Benefits

 Benefits are recorded when paid.


E.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of additions to and deduction from Plan assets during the reporting period.  Actual results could differ from those estimates.


F.

Risks and Uncertainties

The Plan provides for investment options in mutual funds.  Investment securities held by mutual funds are exposed to various risks, such as interest rate, market and credit.  Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants’ account balances and the amounts reported in the statements of net assets available for plan benefits.


G.

Investment Options

Upon enrollment in the Plan, a participant may direct his/her account balance into any of the investment options listed on the schedule of assets (held at end of year).

3.

Employer Contribution


The Company approved discretionary contributions for 2005 and 2004 of $29,994,934 and $28,349,961, respectively.  The Company made matching contributions aggregating $7,871,946 in 2005 and $7,608,553 in 2004.  These Company contributions were transferred to the Plan subsequent to December 31 of each year, and accordingly, are included in contributions receivable in the financial statements.

6.

Plan Termination


Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA.  In the event of Plan termination, participants would become fully vested in their accounts.



7.

Income Tax Status


The Internal Revenue Service has determined and informed the Company by a letter dated August 31, 2004, that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (“IRC”). Although the Plan has been amended since receiving the determination letter, the Plan administrator and the Plan’s tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC.



8.

Forfeitures


Terminating members of the Plan are paid the current value of the vested balance in their plan account as soon as administratively feasible.  Unvested amounts are forfeited and reallocated to continuing participants in the year in which they are forfeited.  As of December 31, 2005 and 2004, forfeitures totaled $759,233 and $858,162, respectively.  Forfeitures are allocated in subsequent years based on the respective profit sharing allocations.  During 2005, $843,214 in forfeitures were credited to participant accounts.

Other Matters


The Plan invests in shares of Legg Mason, Inc. common stock which qualifies as a party-in-interest transaction, through two plan alternatives, one of which is a unitized fund consisting primarily of shares of the common stock of Legg Mason, Inc. The other consists of common stock transferred in from an old plan.  Sales of 87,765 shares or $9,767,270 of Legg Mason, Inc. common stock were made during 2005.  There were no purchases of Legg Mason, Inc. common stock during 2005.  The market value of Legg Mason, Inc. common stock at December 31, 2005 and 2004 was $13,574,270 (113,412 shares) and $14,738,219 (201,177 shares), respectively.


Cash balances maintained by the Plan and the Legg Mason, Inc. common stock directly owned by the Plan are held by M&T Bank and Deutche Bank, respectively, in investment accounts.  The shares of common stock held by the unitized Legg Mason Common Stock Fund are held by a third party custodian.


Sales of 821,659 shares or $42,160,610 and purchases of 597,415 shares or $26,327,012 of the Legg Mason Common Stock Fund units were made during 2005.  The market value of the Legg Mason Common Stock Fund at December 31, 2005 and 2004 was $60,656,354 (1,025,434 units) and $45,088,384 (1,249,678 units), respectively.


Legg Mason Investor Services serves as distributor for the Legg Mason funds held by the Plan.  Additionally, certain affiliated participating and non-participating companies act as manager or investment advisor for the Legg Mason funds.  The Legg Mason funds in the Plan qualify as a party-in-interest.



10.

Subsequent Events


On December 1, 2005, Legg Mason, Inc. acquired substantially all of Citigroup, Inc.'s worldwide asset management business ("CAM") in exchange for Legg Mason's Private Client and Capital Markets ("PC/CM") business, common and preferred stock and cash.  As a result of the exchange, approximately 2,600 PC/CM employees were terminated and may transfer their assets out of the Plan.  Approximately $247,700,000 in PC/CM assets have been transferred out in 2006.  On January 1, 2006, approximately 1,300 CAM employees became eligible to participate in the Plan.  To date, $23,500,000 in assets have been rolled into the Plan.


On February 16, 2006, the Legg Mason Cash Reserve Trust Fund was liquidated.  The balance in the fund, $32,457,643, was automatically transferred to the Citi Institutional Reserve Fund Class A, unless otherwise directed by an individual participant.
