Chairman, President and Chief Executive Officer

Dear Shareholder,

U.S. economic growth was mixed during the 12-month reporting period. After gross domestic product (“GDP”)ⁱ increased 1.7% in the fourth quarter of 2005, the economy then rebounded sharply in the first quarter of 2006. Over this period, GDP rose 5.6%, its best showing since the third quarter of 2003. In the second quarter of 2006, GDP growth was 2.6% and it further moderated to 2.0% in the third quarter. The economy then strengthened in the fourth quarter, due largely to increased consumer spending. Over this time, the advance estimate for GDP growth was 3.5%.

After increasing the federal funds rateⁱⁱ to 5.25% in June—its 17^th consecutive rate hike—the Federal Reserve Board (“Fed”)ⁱⁱⁱ paused from raising rates at its next five meetings. In its statement accompanying the January 2007 meeting, the Fed stated, “Recent indicators have suggested somewhat firmer economic growth, and some tentative signs of stabilization have appeared in the housing market. Readings on core inflation have improved modestly in recent months, and inflation pressures seem likely to moderate over time.”

During the reporting period, short- and long-term Treasury yields experienced periods of significant volatility. After peaking in late June with two–and 10–year Treasuries hitting 5.29% and 5.25%, respectively—rates fell sharply as the Fed paused from its tightening cycle. In addition, inflationary pressures eased as oil prices fell after reaching a record high in mid-July. Overall, during the 12 months ended December 31, 2006, two-year Treasury yields increased from 4.41% to 4.82%. Over the same period, 10-year Treasury yields moved from 4.39% to 4.71%. Looking at the 12-month period as a whole, the overall bond market, as measured by the Lehman Brothers U.S. Aggregate Index^iv, returned 4.33%.

Information About Your Fund

As you may be aware, several issues in the mutual fund industry have come under the scrutiny of federal and state regulators. Affiliates of the Fund’s manager have, in recent years, received requests for information from various government regulators regarding market timing, late trading, fees, and other mutual fund issues in connection with various investigations. The regulators appear to be examining, among other things, the Fund’s response to market timing and shareholder exchange activity, including compliance with prospectus disclosure related to these subjects. The Fund is not in a position to predict the outcome of these requests and investigations.

Legg Mason Partners Government Securities Fund III

Fund Overview

Q. What were the overall market conditions during the Fund’s reporting period?

A. The economy weakened during the period due, in part, to the lagged effect of higher short-term interest rates and a rapidly cooling housing market. Inflationary pressures intensified during the first half of the reporting period. However, as oil prices retreated from their July record high and housing prices moderated, inflation became less of an issue. The Federal Reserve Board (“Fed”)ⁱ boosted its target federal funds rateⁱⁱ from 4.25% when the reporting period began to 5.25% in June 2006. The Fed then held rates steady during the remainder of the reporting period.

Turning to the bond market, the Treasury yield curveⁱⁱⁱ flattened in 2006, as the difference between short- and long-term yields narrowed. Throughout much of 2006, the Treasury yield curve was inverted, with two-year Treasury yields surpassing their 10-year counterparts. Historically, this anomaly has often been a precursor of slowing economic growth and, in many cases, a recession^iv.

2 Legg Mason Partners Government Securities Fund 2006 Annual Report

Q. What were the most significant factors affecting Fund performance?

What were the leading contributors to performance?

A. During the reporting period, a large overweight to mortgage pass-through securities issued by the Federal National Mortgage Association (Fannie Mae)^viiienhanced results, as they outperformed the Fund’s benchmark. In addition, our emphasis on lower coupon securities had a positive impact on performance for the 12-month period ended December 31, 2006.

What were the leading detractors from performance?

A. We sought to diversify the Fund’s portfolio with a moderate allocation to agency and asset-backed securities. However, this detracted from results as they underperformed mortgages. In addition, a slightly long duration^ix position at the very front end of the yield curve was a drag on performance. Early in the year, the combination of strong economic growth and mounting inflationary pressures caused the Fed to raise short-term interest rates longer than expected. As a result, the yield curve inverted, with two-year Treasury yields surpassing their 10-year counterparts.

Q. Were there any significant changes to the Fund during the reporting period?

A. There were no significant changes during the period.

Thank you for your investment in Legg Mason Partners Government Securities Fund. As always, we appreciate that you have chosen us to manage your assets and we remain focused on achieving the Fund’s investment goals.

RISKS: Keep in mind, fixed-income securities are subject to interest rate, credit and market risks. As interest rates rise, bond prices fall, reducing the value of the Fund’s share price.

Please note that the Fund’s shares are not guaranteed by the U.S. government or its agencies. The Fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance.

Fund Expenses (unaudited)

Example

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs, including front-end and back-end sales charges (loads) on purchase payments; and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses. This example is 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.

This example is based on an investment of $1,000 invested on July 1, 2006 and held for the six months ended December 31, 2006.

Actual Expenses

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

Fund Expenses (unaudited) (continued)

Hypothetical Example for Comparison Purposes

The table below titled “Based on Hypothetical Total Return” provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5.00% 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 the information provided in this table to compare the ongoing costs of investing in the Fund and other funds. To do so, compare the 5.00% hypothetical example relating to the Fund with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table below are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as front-end or back-end sales charges (loads). Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Legg Mason Partners Government Securities Fund 2006 Annual Report 21

Notes to Financial Statements

1. Organization and Significant Accounting Policies

Legg Mason Partners Government Securities Fund (formerly known as Smith Barney Government Securities Fund) (the "Fund") is a separate diversified series of Legg Mason Partners Investment Funds, Inc. (formerly known as Smith Barney Investment Funds Inc.) (the "Company"). The Company, a Maryland corporation, is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company.

The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”). Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ.

(a) Investment Valuation. Securities are valued at the mean between the bid and asked prices based on market quotations for those securities, or if no quotations are available, then for securities of similar type, yield and maturity. Securities for which market quotations are not readily available or where market quotations are determined not to reflect fair value, will be valued in good faith by or under the direction of the Fund’s Board of Directors. Short-term obligations with maturities of 60 days or less are valued at amortized cost, which approximates market value.

(b) Repurchase Agreements. When entering into repurchase agreements, it is the Fund's policy that its custodian or a third party custodian take possession of the underlying collateral securities, the market value of which at least equals the principal amount of the repurchase transaction, including accrued interest. To the extent that any repurchase transaction exceeds one business day, the value of the collateral is marked-to-market to ensure the adequacy of the collateral. If the seller defaults, and the market value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited.

(c) Financial Futures Contracts. The Fund may enter into financial futures contracts typically to hedge a portion of the portfolio. Upon entering into a financial futures contract, the Fund is required to deposit cash or securities as initial margin. Additional securities are also segregated up to the current market value of the financial futures contracts. Subsequent payments, known as variation margin, are made or received by the Fund each day, depending on the daily fluctuation in the value of the underlying financial instruments. The Fund recognizes an unrealized gain or loss equal to the daily variation margin. When the financial futures contracts are closed, a realized gain or loss is recognized equal to the difference between the proceeds from (or cost of) the closing transactions and the Fund’s basis in the contracts.

The risks associated with entering into financial futures contracts include the possibility that a change in the value of the contract may not correlate with the changes in the value of the underlying instruments. In addition, investing in financial futures contracts involves the risk that the Fund could lose more than the original margin deposit and subsequent payments required for a futures transaction. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

22 Legg Mason Partners Government Securities Fund 2006 Annual Report

Notes to Financial Statements (continued)

(d) Written Options. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability, the value of which is marked-to-market daily to reflect the current market value of the option written. If the option expires, the Fund realizes a gain from investments equal to the amount of the premium received. When a written call option is exercised, the difference between the premium and the amount for effecting a closing purchase transaction, including brokerage commission, is also treated as a realized gain or loss. When a written put option is exercised, the amount of the premium received reduces the cost of the security purchased by the Fund.

A risk in writing a covered call option is that the Fund may forego 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 the Fund may incur a loss if the market price of the underlying security decreases and the option is exercised. The risk in writing a call option is that the Fund is exposed to the risk of loss if the market price of the underlying security increases. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.

(e) Securities Traded on a To-Be-Announced Basis. The Fund may trade securities on a to-be-announced (“TBA”) basis. In a TBA transaction, the Fund commits to purchasing or selling securities which have not yet been issued by the issuer and for which specific information is not known, such as the face amount and maturity date and the underlying pool of investments in U.S. government agency mortgage pass-through transactions. Securities purchased on a TBA basis are not settled until they are delivered to the Fund, normally 15 to 45 days later. Beginning on the date the Fund enters into a TBA transaction, cash, U.S. government securities or other liquid high-grade debt obligations are segregated in an amount equal in value to the purchase price of the TBA security. These transactions are subject to market fluctuations and their current value is determined in the same manner as for other securities.

(f) Mortgage Dollar Rolls. The Fund enters into dollar rolls in which the Fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon and maturity) securities to settle on a specified future date. During the roll period, the Fund forgoes principal and interest paid on the securities. The Fund is compensated by a fee paid by the counterparty, often in the form of a drop in the repurchase price of the securities. Dollar rolls are accounted for as financing arrangements; the fee is accrued into interest income ratably over the term of the dollar roll and any gain or loss on the roll is deferred and realized upon disposition of the rolled security.

The risk of entering into a mortgage dollar roll is that the market value of the securities the Fund is obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a mortgage dollar roll files for bankruptcy or becomes insolvent, the Fund’s use of proceeds of the dollar roll may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund’s obligation to repurchase the securities.

Legg Mason Partners Government Securities Fund 2006 Annual Report 23

Notes to Financial Statements (continued)

(g) Security Transactions and Investment Income. Security transactions are accounted for on a trade date basis. Interest income, adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults on an expected interest payment, the Fund’s policy is to generally halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default.

(h) Distributions to Shareholders. Distributions from net investment income on the shares of the Fund are declared each business day to shareholders of record, and are paid monthly. Distributions of net realized gains, if any, are declared at least annually. Distributions are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(i) Class Accounting. Investment income, common expenses and realized/unrealized gain (loss) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Fees relating to a specific class are charged directly to that class.

(j) Federal and Other Taxes. It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute substantially all of its income and net realized gains on investments, if any, to shareholders each year. Therefore, no federal income tax provision is required in the Fund’s financial statements.

(k) Reclassification. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. During the current year, the following reclassifications have been made:



	Undistributed Net Investment Income		Accumulated Net Realized Loss		Paid-in Capital
(a)	$	117,864	$	2,822,382	$	(2,940,246)
(b)		1,855,965		(1,855,965)		—

(a)	Reclassifications are primarily due to the expiration of a capital loss carryforward and book/tax differences in the treatment of various items.

(b)	Reclassifications are primarily due to differences between book and tax amortization of premium on fixed income securities and income from mortgage backed securities treated as capital gains for tax purposes.

2.	Investment Management Agreement and Other Transactions with Affiliates

Prior to August 1, 2006, Smith Barney Fund Management LLC (“SBFM”), a wholly-owned subsidiary of Legg Mason, Inc. (“Legg Mason”), acted as the investment manager of the Fund. Under the investment management agreement, the Fund pays an investment management fee calculated daily and paid monthly in accordance with the following breakpoint schedule:



Average Daily Net Assets	Annual Rate
First $2 billion	0.55	%
Next $2 billion	0.50
Next $2 billion	0.45
Next $2 billion	0.40
Over $8 billion	0.35

Effective August 1, 2006, Legg Mason Partners Fund Advisor, LLC (“LMPFA”) became the Fund’s investment manager and Western Asset Management Company (“Western Asset”) became the Fund’s subadviser. The portfolio managers who are responsible for the day-to day management of the Fund remained the same immediately prior to and immediately after the date of these changes. LMPFA and Western Asset are wholly-owned subsidiaries of Legg Mason.

LMPFA provides administrative and certain oversight services to the Fund. LMPFA has delegated to the subadviser the day-to day portfolio management of the Fund. The Fund’s investment management fee remains unchanged. For its services, LMPFA pays Western Asset 70% of the net management fee that it receives from the Fund.

During the year ended December 31, 2006, SBFM and LMPFA waived a portion of their investment management fee in the amount of $13,458. In addition, during the year ended December 31, 2006, the Fund was reimbursed for expenses in the amount of $18,035.

Citigroup Global Markets Inc. (“CGM”), PFS Investments Inc. (“PFS”) and Legg Mason Investor Services, LLC (“LMIS”) serve as distributors of the Fund. LMIS is a wholly-owned broker-dealer subsidiary of Legg Mason.

There is a maximum initial sales charge of 6.75% and 4.25% for Class 1 and A shares, respectively. Effective November 20, 2006, the maximum initial sales charge on Class A shares of the Fund decreased from 4.50% to 4.25% for shares purchased on or after that date. There is a contingent deferred sales charge (“CDSC”) of 4.50% on Class B shares, which applies if redemption occurs within one year from purchase payment. This CDSC declines thereafter by 0.50% per year until no CDSC is incurred. Class C shares have a 1.00% CDSC, which applies if redemption occurs within one year from purchase payment. In certain cases, Class A shares have a 1.00% CDSC, which applies if redemption occurs within one year from purchase payment. This CDSC only applies to those purchases of Class A shares, which, when combined with current holdings of Class A shares, equal or exceed $500,000 in the aggregate. These purchases do not incur an initial sales charge.

7. Income Tax Information and Distributions to Shareholders

Subsequent to the fiscal year end, the Fund has made the following distributions:



Record Date Payable Date	Class 1		Class A		Class B		Class C		Class I
Daily 1/31/2007	$	0.043849	$	0.040632	$	0.035101	$	0.037668	$	0.044051

The tax character of distributions paid during the fiscal years ended December 31, were as follows:

As of December 31, 2006, the components of accumulated earnings on a tax basis were as follows:


Undistributed ordinary income - net	$	366,802
Capital loss carryforward*		(83,745,003	)
Other book/tax temporary differences^(a)		382,146
Unrealized appreciation/(depreciation)^(b)		2,724,881

Total accumulated earnings / (losses) — net	$	(80,271,174	)

As of December 31, 2006, the Fund had the following net capital loss carryforward remaining:


Year of Expiration	Amount
12/31/2007	$	(48,857,876	)
12/31/2008		(16,358,450	)
12/31/2012		(2,474,230	)
12/31/2013		(3,821,875	)
12/31/2014		(12,232,572	)

	$	(83,745,003	)

These amounts will be available to offset any future taxable capital gains.

^(a)

Other book/tax temporary differences are attributable primarily to the tax deferral of losses on straddles, the realization for tax purposes of unrealized gains/(losses) on certain futures contracts and differences in the book/tax treatment of various items.

^(b)

The difference between book-basis and tax-basis unrealized application/(depreciation) is attributable primarily to the tax deferral of losses on wash sales.

8. Regulatory Matters

On May 31, 2005, the U.S. Securities and Exchange Commission (“SEC”) issued an order in connection with the settlement of an administrative proceeding against SBFM, the Fund’s prior investment manager, and CGM relating to the appointment of an affiliated transfer agent for the Smith Barney family of mutual funds (the “Funds”).

The SEC order finds that SBFM and CGM willfully violated Section 206(1) of the Investment Advisers Act of 1940 (“Advisers Act”). Specifically, the order finds that SBFM and CGM knowingly or recklessly failed to disclose to the boards of the Funds in 1999

Legg Mason Partners Government Securities Fund 2006 Annual Report 29

Notes to Financial Statements (continued)

when proposing a new transfer agent arrangement with an affiliated transfer agent that: First Data Investors Services Group (“First Data”), the Funds’ then-existing transfer agent, had offered to continue as transfer agent and do the same work for substantially less money than before; and that Citigroup Asset Management (“CAM”), the Citigroup business unit that, at the time, included the Fund’s investment manager and other investment advisory companies, had entered into a side letter with First Data under which CAM agreed to recommend the appointment of First Data as sub-transfer agent to the affiliated transfer agent in exchange for, among other things, a guarantee by First Data of specified amounts of asset management and investment banking fees to CAM and CGM. The order also finds that SBFM and CGM willfully violated Section 206(2) of the Advisers Act by virtue of the omissions discussed above and other misrepresentations and omissions in the materials provided to the Funds’ boards, including the failure to make clear that the affiliated transfer agent would earn a high profit for performing limited functions while First Data continued to perform almost all of the transfer agent functions, and the suggestion that the proposed arrangement was in the Funds’ best interests and that no viable alternatives existed. SBFM and CGM do not admit or deny any wrongdoing or liability. The settlement does not establish wrongdoing or liability for purposes of any other proceeding.

The SEC censured SBFM and CGM and ordered them to cease and desist from violations of Sections 206(1) and 206(2) of the Advisers Act. The order requires Citigroup to pay $208.1 million, including $109 million in disgorgement of profits, $19.1 million in interest, and a civil money penalty of $80 million. Approximately $24.4 million has already been paid to the Funds, primarily through fee waivers. The remaining $183.7 million, including the penalty, has been paid to the U.S. Treasury and will be distributed pursuant to a plan submitted for the approval of the SEC. At this time, there is no certainty as to how the above-described proceeds of the settlement will be distributed, to whom such distributions will be made, the methodology by which such distributions will be allocated, and when such distributions will be made. The order also required that transfer agency fees received from the Funds since December 1, 2004, less certain expenses, be placed in escrow and provided that a portion of such fees might be subsequently distributed in accordance with the terms of the order. On April 3, 2006, an aggregate amount of approximately $9 million was distributed to the affected Funds.

The order required SBFM to recommend a new transfer agent contract to the Funds’ boards within 180 days of the entry of the order; if a Citigroup affiliate submitted a proposal to serve as transfer agent or sub-transfer agent, SBFM and CGM would have been required, at their expense, to engage an independent monitor to oversee a competitive bidding process. On November 21, 2005, and within the specified timeframe, the Fund’s Board selected a new transfer agent for the Fund. No Citigroup affiliate submitted a proposal to serve as transfer agent. Under the order, SBFM also must comply with an amended version of a vendor policy that Citigroup instituted in August 2004.

Although there can be no assurance, the Fund’s manager does not believe that this matter will have a material adverse effect on the Fund.

On December 1, 2005, Citigroup completed the sale of substantially all of its global asset management business, including SBFM, to Legg Mason.

9. Legal Matters

Beginning in August 2005, five class action lawsuits alleging violations of federal securities laws and state law were filed against CGM and SBFM, (collectively, the “Defendants”) based on the May 31, 2005 settlement order issued against the Defendants by the SEC as described in Note 8. The complaints seek injunctive relief and compensatory and punitive damages, removal of SBFM as the advisor for the Smith Barney family of funds, rescission of the Funds’ management and other contracts with SBFM, recovery of all fees paid to SBFM pursuant to such contracts, and an award of attorneys’ fees and litigation expenses.

On October 5, 2005, a motion to consolidate the five actions and any subsequently filed, related action was filed. That motion contemplates that a consolidated amended complaint alleging substantially similar causes of action will be filed in the future.

As of the date of this report, the Fund’s manager believes that resolution of the pending lawsuit will not have a material effect on the financial position or results of operations of the Fund or the ability of the Fund’s manager and its affiliates to continue to render services to the Fund under their respective contracts.

* * *

Beginning in June 2004, class action lawsuits alleging violations of the federal securities laws were filed against CGM and a number of its then affiliates, including SBFM and Salomon Brothers Asset Management Inc (“SBAM”), which were then investment adviser or manager to certain of the Funds (the “Managers”), substantially all of the mutual funds then managed by the Managers (the “Defendant Funds”), and Board members of the Defendant Funds (collectively, the “Defendants”). The complaints alleged, among other things, that CGM created various undisclosed incentives for its brokers to sell Smith Barney and Salomon Brothers funds. In addition, according to the complaints, the Managers caused the Defendant Funds to pay excessive brokerage commissions to CGM for steering clients towards proprietary funds. The complaints also alleged that the Defendants breached their fiduciary duty to the Defendant Funds by improperly charging Rule 12b-1 fees and by drawing on fund assets to make undisclosed payments of soft dollars and excessive brokerage commissions. The complaints also alleged that the Defendant Funds failed to adequately disclose certain of the allegedly wrongful conduct. The complaints sought injunctive relief and compensatory and punitive damages, rescission of the Defendant Funds’ contracts with the Managers, recovery of all fees paid to the Managers pursuant to such contracts and an award of attorneys’ fees and litigation expenses.

On December 15, 2004, a consolidated amended complaint (the “Complaint”) was filed alleging substantially similar causes of action. On May 27, 2005, all of the Defendants filed motions to dismiss the Complaint. On July 26, 2006, the court issued a decision and order (1) finding that plaintiffs lacked standing to sue on behalf of the shareholders of the Funds in which none of the plaintiffs had invested and dismissing those Funds from the case (although stating that they could be brought back into the case if standing as to them could be established), and (2) other than one stayed claim, dismissing all of the causes of action against the remaining Defendants, with prejudice, except for the cause of

Legg Mason Partners Government Securities Fund 2006 Annual Report 31

Notes to Financial Statements (continued)

action under Section 36(b) of the 1940 Act, which the court granted plaintiffs leave to repeal as a derivative claim.

On October 16, 2006, plaintiffs filed their Second Consolidated Amended Complaint (“Second Amended Complaint”) which alleges derivative claims on behalf of nine funds identified in the Second Amended Complaint, under Section 36(b) of the 1940 Act, against CAM, SBAM, SBFM and CGM as investment advisers to the identified funds, as well as CGM as a distributor for the identified funds (collectively, the “Second Amended Complaint Defendants”). The Fund was not identified in the Second Amended Complaint. The Second Amended Complaint alleges no claims against any of the funds or any of their Board members. Under Section 36(b), the Second Amended Complaint alleges similar facts and seeks similar relief against the Second Amended Complaint Defendants as the Complaint.

Additional lawsuits arising out of these circumstances and presenting similar allegations and requests for relief may be filed in the future.

10. Other Matters

On September 16, 2005, the staff of the SEC informed SBFM and SBAM that the staff is considering recommending that the SEC institute administrative proceedings against SBFM and SBAM for alleged violations of Section 19(a) and 34(b) of the 1940 Act (and related Rule 19a-1). The notification is a result of an industry wide inspection by the SEC and is based upon alleged deficiencies in disclosures regarding dividends and distributions paid to shareholders of certain funds. Section 19(a) and related Rule 19a-1 of the 1940 Act generally require funds that are making dividend and distribution payments to provide shareholders with a written statement disclosing the source of the dividends and distributions, and, in particular, the portion of the payments made from each of net investment income, undistributed net profits and/or paid-in capital. In connection with the contemplated proceedings, the staff may seek a cease and desist order and/or monetary damages from SBFM or SBAM.

Although there can be no assurance, the Fund’s manager believes that this matter is not likely to have a material adverse effect on the Fund.

11. Special Shareholder Meeting and Reorganization

The Board and the shareholders of the Legg Mason Partners U.S. Government Securities Fund (the “Acquired Fund”) and the Board of the Fund approved at the October 2006 shareholder meeting, an Agreement and Plan of Reorganization providing for the acquisition of all of the assets and the assumption of all the liabilities of the Acquired Fund, in exchange for shares of the Fund. The reorganization occurred on February 2, 2007.

Shareholders also approved a number of initiatives designed to streamline and restructure the fund complex. These matters generally are expected to be implemented in 2007. As noted in the proxy materials, Legg Mason will pay for a portion of the costs related to these initiatives. The portion of the costs that are borne by the Fund will be recognized in the period during which the expense is incurred. Such expenses relate to obtaining shareholder votes for proposals presented in the proxy, the election of board

members, retirement of board members, as well as printing, mailing, and soliciting proxies. See also “Additional Shareholder Information” at the end of this report.

12. Recent Accounting Pronouncements

During June 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation 48 (“FIN 48” or the “Interpretation”), Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement 109. FIN 48 supplements FASB Statement 109, Accounting for Income Taxes, by defining the confidence level that a tax position must meet in order to be recognized in the financial statements. FIN 48 prescribes a comprehensive model for how a fund should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the fund has taken or expects to take on a tax return. FIN 48 requires that the tax effects of a position be recognized only if it is “more likely than not” to be sustained based solely on its technical merits. Management must be able to conclude that the tax law, regulations, case law, and other objective information regarding the technical merits sufficiently support the position’s sustainability with a likelihood of more than 50 percent. FIN 48 is effective for fiscal periods beginning after December 15, 2006, which for this Fund will be January 1, 2007. At adoption, the financial statements must be adjusted to reflect only those tax positions that are more likely than not to be sustained as of the adoption date. Management of the Fund has determined that adopting FIN 48 will not have a material impact on the Fund’s financial statements.

* * *

On September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 Fair Value Measurements (“FAS 157”). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact on the financial statements has not yet been determined.

The aggregate fees billed in the last two fiscal years ending December 31, 2005 and December 31, 2006 (the “Reporting Periods”) for professional services rendered by the Registrant’s principal accountant (the “Auditor”) for the audit of the Registrant’s annual financial statements, or services that are normally provided by the Auditor in connection with the statutory and regulatory filings or engagements for the Reporting Periods, were $55,000 in 2005 and $55,000 in 2006.

b) Audit-Related Fees. There were no fees billed in the Reporting Periods for assurance and related services by the Auditor that are reasonably related to the performance of the audit of the Registrant’s financial statements and are not reported under paragraph (a) of this Item 4.

In addition, there were no Audit-Related Fees billed in the Reporting Period for assurance and related services by the Auditor to the Registrant’s investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the Legg Mason Partners Investment Funds Inc. (“service affiliates”), that were reasonably related to the performance of the annual audit of the service affiliates. Accordingly, there were no such fees that required pre-approval by the Audit Committee for the Reporting Periods (prior to May 6, 2003 services provided by the Auditor were not required to be pre-approved).

(c) Tax Fees. The aggregate fees billed in the Reporting Periods for professional services rendered by the Auditor for tax compliance, tax advice and tax planning (“Tax Services”) were $4,700 in 2005 and $4,700 in 2006.

There were no fees billed for tax services by the Auditors to service affiliates during the Reporting Periods that required pre-approval by the Audit Committee.

d) All Other Fees. There were no other fees billed in the Reporting Periods for products and services provided by the Auditor, other than the services reported in paragraphs (a) through (c) of this Item for the Legg Mason Partners Investment Funds Inc.

All Other Fees. There were no other non-audit services rendered by the Auditor to Smith Barney Fund Management LLC (“SBFM”), and any entity controlling, controlled by or under common control with SBFM that provided ongoing services to Legg Mason Partners Investment Funds Inc.requiring pre-approval by the Audit Committee in the Reporting Period.

(e) Audit Committee’s pre–approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

(1) The Charter for the Audit Committee (the “Committee”) of the Board of each registered investment company (the “Fund”) advised by Smith Barney Fund Management LLC or Salomon Brothers Asset Management Inc. or one of their affiliates (each, an “Adviser”) requires that the Committee shall approve (a) all audit and permissible non-audit services to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund’s independent auditors to the Adviser and any Covered Service Providers if the engagement relates directly to the operations and financial reporting of the Fund. The Committee may implement policies and procedures by which such services are approved other than by the full Committee.

The Committee shall not approve non-audit services that the Committee believes may impair the independence of the auditors. As of the date of the approval of this Audit Committee Charter, permissible non-audit services include any professional services (including tax services), that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may not include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, the Adviser and any service providers controlling, controlled by or under common control with the Adviser that provide ongoing services to the Fund (“Covered Service Providers”) constitutes not more than 5% of the total amount of revenues paid to the independent auditors during the fiscal year in which the permissible non-audit services are provided to (a) the Fund, (b) the Adviser and (c) any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit.

(2) For the Legg Mason Partners Investment Trust, the percentage of fees that were approved by the audit committee, with respect to: Audit-Related Fees were 100% and 0% for 2005 and 2006; Tax Fees were 100% and 0% for 2005 and 2006; and Other Fees were 100% and 0% for 2005 and 2006.

(f) N/A

(g) Non-audit fees billed by the Auditor for services rendered to Legg Mason Partners Investment Funds Inc. and CAM and any entity controlling, controlled by, or under common control with CAM that provides ongoing services to Legg Mason Partners Investment Funds Inc. during the reporting period were $0 in 2006 for fees related to the transfer agent matter as fully described in the notes the financial statements titled “additional information” and $75,000 for 2005.

(h) Yes. Legg Mason Partners Investment Funds Inc.’s Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Accountant’s independence. All services provided by the Auditor to the Legg Mason Partners Investment Funds Inc. or to Service Affiliates, which were required to be pre-approved, were pre-approved as required.
