Bond ratings (unaudited)

The definitions of the applicable rating symbols are set forth below:

Standard & Poor’s Ratings Service (“Standard & Poor’s”) — Ratings from “AA” to “CCC” may be modified by the addition of a plus (+) or minus (–) sign to show relative standings within the major rating categories.

AAA	—	Bonds rated “AAA” have the highest rating assigned by Standard & Poor’s. Capacity to pay interest and repay principal is extremely strong.
AA	—	Bonds rated “AA” have a very strong capacity to pay interest and repay principal and differ from the highest rated issues only in a small degree.
A	—	Bonds rated “A” have a strong capacity to pay interest and repay principal although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.
BBB	—	Bonds rated “BBB” are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for bonds in this category than in higher rated categories.
BB, B, CCC,
CC and C	—	Bonds rated “BB”, “B”, “CCC”, “CC” and “C” are regarded, on balance, as predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. “BB” represents the lowest degree of speculation and “C” the highest degree of speculation. While such bonds will likely have some quality and protective characteristics, these are outweighed by large uncertainties or major risk exposures to adverse conditions.
D	—	Bonds rated “D” are in default and payment of interest and/or repayment of principal is in arrears.
Moody’s Investors Service (“Moody’s”) — Numerical modifiers 1, 2 and 3 may be applied to each generic rating from “Aa” to “Caa,” where 1 is the highest and 3 the lowest ranking within its generic category.
Aaa	—	Bonds rated “Aaa” are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edge.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.
Aa	—	Bonds rated “Aa” are judged to be of high quality by all standards. Together with the “Aaa” group they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in “Aaa” securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in “Aaa” securities.
A	—	Bonds rated “A” possess many favorable investment attributes and are to be considered as upper medium grade obligations. Factors giving security to principal and interest are considered adequate but elements may be present which suggest a susceptibility to impairment some time in the future.
Baa	—	Bonds rated “Baa” are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well.
Ba	—	Bonds rated “Ba” are judged to have speculative elements; their future cannot be considered as well assured. Often the protection of interest and principal payments may be very moderate and therefore not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

See Notes to Financial Statements.

40 |  Tax Free Reserves Portfolio 2008 Semi-Annual Report

B	—	Bonds rated “B” generally lack characteristics of desirable investments. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.
Caa	—	Bonds rated “Caa” are of poor standing. These may be in default, or present elements of danger may exist with respect to principal or interest.
Ca	—	Bonds rated “Ca” represent obligations which are speculative in a high degree. Such issues are often in default or have other marked short-comings.
C	—	Bonds rated “C” are the lowest class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

Fitch Ratings Service (“Fitch”) — Ratings from “AA” to “CCC” may be modified by the addition of a plus (+) or minus (–) sign to show relative standings within the major rating categories.

AAA	—	Bonds rated “AAA” have the highest rating assigned by Fitch. Capacity to pay interest and repay principal is extremely strong.
AA	—	Bonds rated “AA” have a very strong capacity to pay interest and repay principal and differ from the highest rated issues only in a small degree.
A	—	Bonds rated “A” have a strong capacity to pay interest and repay principal although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.
BBB	—	Bonds rated “BBB” are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for bonds in this category than in higher rated categories.
BB, B, CCC
and CC	—	Bonds rated “BB”, “B”, “CCC” and “CC” are regarded, on balance, as predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. “BB” represents a lower degree of speculation than “B”, and “CC” the highest degree of speculation. While such bonds will likely have some quality and protective characteristics, these are outweighed by large uncertainties or major risk exposures to adverse conditions.
NR	—	Indicates that the bond is not rated by Standard & Poor’s, Moody’s or Fitch.

Short-term security ratings (unaudited)

SP-1	—	Standard & Poor’s highest rating indicating very strong or strong capacity to pay principal and interest; those issues determined to possess overwhelming safety characteristics are denoted with a plus (+) sign.
A-1	—	Standard & Poor’s highest commercial paper and variable-rate demand obligation (VRDO) rating indicating that the degree of safety regarding timely payment is either overwhelming or very strong; those issues determined to possess overwhelming safety characteristics are denoted with a plus (+) sign.
VMIG 1	—	Moody’s highest rating for issues having a demand feature— VRDO.
MIG1	—	Moody’s highest rating for short-term municipal obligations.
P-1	—	Moody’s highest rating for commercial paper and for VRDO prior to the advent of the VMIG 1 rating.
F1	—	Fitch’s highest rating indicating the strongest capacity for timely payment of financial commitments; those issues determined to possess overwhelming strong credit feature are denoted with a plus (+) sign.

Tax Free Reserves Portfolio 2008 Semi-Annual Report  |  45

Notes to financial statements (unaudited)

1. Organization and significant accounting policies

Tax Free Reserves Portfolio (the “Portfolio”) is a no-load, non-diversified investment series of Master Portfolio Trust (the “Trust”). The Trust, a Maryland business Trust, is registered under the investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. At February 29, 2008, all investors in the Portfolio were funds advised by the manager of the fund and/or its affiliates.

The following are significant accounting policies consistently followed by the Portfolio 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. Money market instruments are valued at amortized cost, in accordance with Rule 2a-7 under the 1940 Act, which approximates market value. This method involves valuing portfolio securities at their cost and thereafter assuming a constant amortization to maturity of any discount or premium. The Portfolio’s use of amortized cost is subject to their compliance with certain conditions as specified by Rule 2a-7 of the 1940 Act.

(b) Interest income and expenses. Interest income consists of interest accrued and discount earned (including both original issue and market discount adjusted for amortization of premium) on the investments of the Portfolio. Expenses of the Portfolio are accrued daily. The Portfolio bears all costs of its operations other than expenses specifically assumed by the manager.

(c) Credit and market risk. The Fund may invest in instruments specifically structured so that they are eligible for purchase by money market funds, including securities that have demand, tender or put features, or interest rate reset features. Structured instruments may take the form of participation interests or receipts in underlying securities or other assets, and in some cases are backed by a financial institution serving as a liquidity provider. Some of these instruments may have an interest rate swap feature which substitutes a floating or variable interest rate for the fixed interest rate on an underlying security, and some may be asset-backed or mortgage-backed securities. Structured instruments are a type of derivative instrument and the payment and credit qualities of these instruments derive from the assets embedded in the structure.

The fair value of these securities may be different than the amortized cost value reported in the Statement of Investments for the Fund. As of the date of this report, the Fund continued to meet the requirements under Rule 2a-7 that permits the Fund to utilize amortized cost to value its securities.

46  |  Tax Free Reserves Portfolio 2008 Semi-Annual Report

(d) Fees paid indirectly. The Portfolio’s custody fees are reduced according to a fee arrangement, which provides for a reduction based on the level of cash deposited with the custodian by the Portfolio. The amount is shown as a reduction of expenses on the Statement of Operations.

(e) Income taxes. The Portfolio is classified as a partnership for federal income tax purposes. As such, each investor in the Portfolio is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Portfolio. Therefore, no Federal income tax provision is required. It is intended that the Portfolio’s assets will be managed so an investor in the Portfolio can satisfy the requirements of the subchapter M of the Internal Revenue Code.

(f) Other. Purchases, maturities and sales of money market instruments are accounted for on the date of the transaction. Realized gains and losses are calculated on the identified cost basis.

2. Investment management agreement and other transactions with affiliates

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) is the Portfolio’s investment manager and Western Asset Management Company (“Western Asset”) is the Portfolio’s subadviser. LMPFA and Western Asset are wholly-owned subsidiaries of Legg Mason, Inc. (“Legg Mason”).

Under the investment management agreement, the Portfolio pays investment management fees, calculated daily and paid monthly, at an annual rate of 0.15% of the Portfolio’s average daily net assets.

LMPFA provides administrative and certain oversight services to the Portfolio. LMPFA delegates to the subadviser the day-to-day portfolio management of the Portfolio. For its services, LMPFA pays Western Asset 70% of the net management fee it receives from the Portfolio.

During the six months ended February 29, 2008, the Portfolio had a voluntary expense limitation in place of 0.15% of the Portfolio’s average daily net assets.

During the six months ended February 29, 2008, LMPFA waived a portion of its fee in the amount of $107,915.

Effective January 1, 2008, the manager is permitted to recapture amounts that it has previously voluntarily waived and/or reimbursed to the Fund during the same fiscal year if the Fund’s total annual operating expenses have fallen to a level below the expense cap shown in the fee table of the Fund’s prospectus. In no case will the manager recapture any amount that would result, on any particular Fund business day, in the Fund’s total annual operating expenses exceeding the expense cap.

On July 10, 2006, a retirement plan applicable to the Portfolio was amended by the Board then overseeing the Portfolio (the “previous Board”) to provide for the payment of certain benefits (in lieu of any other retirement payments under any previous plans) to Trustees who had not elected to retire as of April 2007. All of Trustees comprising the previous Board (and who had not elected to retire as of April 2007) elected to receive benefits under the amended plan. Each fund overseen by the previous Board (including the portfolio) paid its pro rata share (based upon assets size) of such benefits to the Trustees comprising the previous Board. Legg Mason or its affiliates agreed to reimburse the funds an amount equal to 50% of these benefits. The Portfolio’s allocable share of benefits under this amendment at February 29, 2008 was $7,814. Generally benefits under the retirement plan are paid in quarterly installments unless the Trustees elected to receive them in a lump sum at net present value. Two former Trustees are currently receiving payments under retirement plan.

Certain officers and one of the Trustees of the Trust are employees of Legg Mason or its affiliates and not receive compensation from the Trust.

3. Legal matters

Beginning in June 2004, class action lawsuits alleging violations of the federal securities laws were filed against Citigroup Global Markets, Inc. (“CGM”), and other affiliated funds (collectively, the “Funds”), and a number of its then affiliates, including Smith Barney Fund Management LLC (“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

48  |  Tax Free Reserves Portfolio 2008 Semi-Annual Report

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 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 Citigroup Asset Management (“CAM”), SBAM and SBFM 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.

On December 3, 2007, the court granted the Defendants’ motion to dismiss, with prejudice. On January 2, 2008, the plaintiffs filed a notice of appeal to Second Circuit Court of Appeals.

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

* * *

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 Securities and Exchange Commission (“SEC”) as previously described. The complaints seek injunctive relief and compensatory and punitive damages, removal of SBFM as the investment manager 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. The five actions were subsequently consolidated, and a consolidated complaint was filed.

On September 26, 2007, the United States District Court for the Southern District of New York issued an order dismissing the consolidated complaint, and judgment was later entered. An appeal has been filed and is pending before the U.S. Court of Appeals for the Second Circuit.

4. Other matter

On or about May 30, 2006, John Halebian, a purported shareholder of Citi New York Tax Free Reserves, a series of Legg Mason Partners Money Market Trust, formerly a series of CitiFunds Trust III (the “Subject Trust”), filed a complaint in the United States District Court for the Southern District of New York against the independent trustees of the Subject Trust (Elliott J. Berv, Donald M. Carlton, A. Benton Cocanougher, Mark T. Finn, Stephen Randolph Gross, Diana R. Harrington, Susan B. Kerley, Alan G. Merten and R. Richardson Pettit).

The Subject Trust is also named in the complaint as a nominal defendant. The complaint alleges both derivative claims on behalf of the Subject Trust and class claims on behalf of a putative class of shareholders of the Subject Trust in connection with the 2005 sale of Citigroup’s asset management business to Legg Mason and the related approval of new investment advisory agreements by the trustees and shareholders. In the derivative claim, the plaintiff alleges, among other things, that the independent trustees breached their fiduciary duty to the Subject Trust and its shareholders by failing to negotiate lower fees or seek competing bids from other qualified investment advisers in connection with Citigroup’s sale to Legg Mason. In the claims brought on behalf of the putative class of shareholders, the plaintiff alleges that the independent trustees violated the proxy solicitation requirements of the 1940 Act, and breached their fiduciary duty to shareholders, by virtue of the voting procedures, including “echo voting,” used to obtain approval of the new investment advisory agreements and statements made in a proxy statement regarding those voting procedures. The plaintiff alleges that the proxy statement was misleading because it failed to disclose that the voting procedures violated the 1940 Act. The relief sought includes an award of damages, rescission of the advisory agreement, and an award of costs and attorney fees.

In advance of filing the complaint, Mr. Halebian’s lawyers made written demand for relief on the Board of the Subject Trust, and the Board’s independent trustees formed a demand review committee to investigate the matters raised in the demand, and subsequently in the complaint, and recommend a course of action to the Board. The committee, after a thorough review, determined that the independent trustees did not breach their fiduciary duties as alleged by Mr. Halebian, and that the action demanded by Mr. Halebian would not be in the best interests of the Subject Trust. The Board of the Subject Trust (the trustee who is an “interested person” of the Subject Trust, within the meaning of the 1940 Act, having recused himself from the matter), after receiving and considering the committee’s report and based upon the findings of the committee, subsequently also so determined and, adopting the recommendation of the committee, directed counsel to move to dismiss Mr. Halebian’s complaint. A motion to dismiss was filed on October 23, 2006. Opposition papers were filed on or about December 7, 2006. The complaint was dismissed on July 31, 2007. Mr. Halebian has filed an appeal in the U.S. Court of Appeals for the Second Circuit. The appeal is pending.

5. Recent accounting pronouncements

On September 20, 2006, the Financial Accounting Standard Board (“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. Management has determined that there is no material impact to the Portfolio’s valuation policies as a result of adopting FAS 157. The Portfolio will implement the disclosure requirements beginning with its November 30, 2008 Form N-Q.

* * *

In March 2008, FASB issued the Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”). SFAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about the Portfolio’s derivative and hedging activities, including how such activities are accounted for and their effect on the Portfolio’s financial position, performance and cash flows. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Portfolio’s financial statements and related disclosures.

6. Recent developments

On May 21, 2007, the United States Supreme Court agreed to hear an appeal in Department of Revenue of Kentucky v. Davis, a case concerning the validity of statutes that create a state tax exemption for interest from municipal securities. The Kentucky Court of Appeals had held that Kentucky’s statute, which provided an exemption for interest earned on municipal securities of Kentucky issuers while taxing interest earned on municipal securities of issuers in other states, violated the Interstate Commerce Clause of the United States Constitution. If the Supreme Court were to adopt the reasoning of the Kentucky Court of Appeals, its decision would affect the state tax status of fund distributions. It is unclear how such a decision would affect the market for municipal securities, but it could adversely affect the value of securities held by the Portfolio, and therefore of the Fund’s shares. Such a decision could also prompt legislation at the state level that would have further impacts upon the taxability of Fund distributions and upon the market for municipal securities. The case was argued before the Supreme Court on November 5, 2007, but no decision has yet been issued.

Board approval of management and
subadvisory agreements (unaudited)

At a meeting of the Board of Trustees of Master Portfolio Trust (the “Trust”) held on November 12-13, 2007, the Board, including the Board members who are not considered to be “interested persons” of the Trust (the “Independent Board Members”) under the Investment Company Act of 1940, as amended (the “1940 Act”), approved for an annual period the continuation of the management agreement (the “Management Agreement”) between the Trust and Legg Mason Partners Fund Advisor, LLC (the “Manager”) with respect to the Tax Free Reserves Portfolio, a series of the Trust (the “Fund”), and the sub-advisory agreement (the “Sub-Advisory Agreement”) between the Manager and Western Asset Management Company (the “Subadviser”), an affiliate of the Manager, with respect to the Fund.

Background

The Board received information in advance of the meeting from the Manager to assist it in its consideration of the Management Agreement and the Sub-Advisory Agreement and was given the opportunity to ask questions and request additional information from management. The Board received and considered a variety of information about the Manager, the Subadviser and the Fund’s placement agent, as well as the management, sub-advisory and placement agency and distribution arrangements for the Fund and other funds overseen by the Board, certain portions of which are discussed below. The Board noted that the Fund is a “master” fund in a “master-feeder” structure, whereby each “feeder fund” has the same investment objective and policies as the Fund and invests substantially all of its assets in the Fund. The presentation made to the Board encompassed the Fund and all funds for which the Board has responsibility, including the following feeder funds in the Fund (each, a “Feeder Fund”): Citi Tax Free Reserves, a series of Legg Mason Partners Money Market Trust, and Citi Institutional Tax Free Reserves, a series of Legg Mason Partners Institutional Trust. The discussion below covers both the advisory and the administrative functions being rendered by the Manager, both of which functions are encompassed by the Management Agreement, as well as the advisory functions rendered by the Subadviser pursuant to the Sub-Advisory Agreement.

Board approval of management agreement and sub-advisory agreement

The Independent Board Members were advised by separate independent legal counsel throughout the process. Prior to voting, the Independent Board Members received a memorandum from their independent legal counsel discussing the legal standards for their consideration of the proposed continuation of the Management Agreement and the Sub-Advisory Agreement. The Independent Board Members also discussed the proposed continuation of the Management Agreement and the Sub-Advisory Agreement in private sessions with their independent legal counsel at which no representatives of the Manager were present. In approving the Management Agreement and Sub-Advisory Agreement, the Board, including the Independent Board Members,

52  |  Tax Free Reserves Portfolio

considered a variety of factors, including those factors discussed below. No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the Management Agreement and the Sub-Advisory Agreement, and each Board Member attributed different weight to the various factors.

Nature, extent and quality of the services under the management agreement and sub-advisory agreement

The Board received and considered information regarding the nature, extent and quality of services provided to the Fund by the Manager and the Subadviser under the Management Agreement and the Sub-Advisory Agreement, respectively, during the past two years. The Board noted information received at regular meetings throughout the year related to the services rendered by the Manager in its management of the Fund’s affairs and the Manager’s role in coordinating the activities of the Fund’s other service providers. The Board’s evaluation of the services provided by the Manager and the Subadviser took into account the Board’s knowledge and familiarity gained as Board members of funds in the Legg Mason Partners fund complex, including the scope and quality of the investment management and other capabilities of the Manager and the Subadviser, and the quality of the Manager’s administrative and other services. The Board observed that the scope of services provided by the Manager and the Subadviser had expanded over time as a result of regulatory and other developments, including maintaining and monitoring their own and the Fund’s expanded compliance programs. The Board reviewed information received from the Manager and the Subadviser regarding the Fund’s compliance policies and procedures established pursuant to Rule 38a-1 under the 1940 Act.

The Board reviewed the qualifications, backgrounds and responsibilities of the Fund’s senior personnel and the portfolio management team primarily responsible for the day-to-day portfolio management of the Fund. The Board also considered the degree to which the Manager implemented organizational changes to improve investment results and the services provided to the Legg Mason Partners fund complex. The Board also considered, based on its knowledge of the Manager and its affiliates, the financial resources available to Legg Mason, Inc., the parent organization of the Manager and the Subadviser.

The Board considered the division of responsibilities between the Manager and the Subadviser and the oversight provided by the Manager. The Board also considered the Manager’s and the Subadviser’s brokerage policies and practices. In addition, management also reported to the Board on, among other things, its business plans, organizational changes and portfolio manager compensation plan.

Tax Free Reserves Portfolio  |  53

Board approval of management and
subadvisory agreements (unaudited) continued

The Board concluded that, overall, the nature, extent and quality of services provided (and expected to be provided) under the Management Agreement and the Sub-Advisory Agreement were satisfactory.

Fund performance

In considering the performance of the Fund, the Board received and considered performance information for the Feeder Funds as well as a group of funds (a “Performance Universe”) selected by Lipper, Inc. (“Lipper”), an independent provider of investment company data, for each Feeder Fund. The Board noted that each Feeder Fund’s performance was the same as the performance of the Fund (except for the effect of fees at the Feeder Fund level), and therefore relevant to the Board’s conclusions regarding the Fund’s performance. The Board was provided with a description of the methodology Lipper used to determine the similarity of each Feeder Fund with the funds included in its Performance Universe. The Board also noted that it had received and discussed with management information throughout the year at periodic intervals comparing each Feeder Fund’s performance against its benchmark.

The information comparing Citi Tax Free Reserves’ performance to that of its Performance Universe, consisting of all retail funds classified as tax-exempt money market funds by Lipper, showed, among other data, that Citi Tax Free Reserves’ performance for the 1- and 3-year periods ended June 30, 2007 was below the median and that performance for the 5-year period ended June 30, 2007 was at the median. The Board noted the explanations from the Manager concerning the underperformance versus the peer group.

The information comparing Citi Institutional Tax Free Reserves’ performance to that of its Performance Universe, consisting of all funds classified as institutional tax-exempt money market funds by Lipper, showed, among other data, that Citi Institutional Tax Free Reserves’ performance for the 1-, 3- and 5-year periods ended June 30, 2007 was above the median.

Based on its review, which included careful consideration of all of the factors noted above, the Board concluded that the Fund’s performance was satisfactory.

Management fees and expense ratios

The Board reviewed and considered the contractual management fee payable by the Fund to the Manager in light of the nature, extent and quality of the management and sub-advisory services provided by the Manager and the Subadviser. The Board also reviewed and considered that fee waiver and/or expense reimbursement arrangements currently are in place for the Fund and considered the actual fee rate (after taking waivers and reimbursements into account) and that the Manager has agreed to continue its fee waivers and reimbursements until further notice. In addition, the Board noted that the

54  |  Tax Free Reserves Portfolio

compensation paid to the Subadviser is paid directly by the Manager, not the Fund, and, accordingly, that the retention of the Subadviser does not increase the fees or expenses otherwise incurred by the Fund’s shareholders.

Additionally, the Board received and considered information comparing each Feeder Fund’s contractual management fee (each, a “Contractual Management Fee”) and the actual fee rate (after taking waivers and reimbursements into account) (each an “Actual Management Fee”) and the Feeder Fund’s overall expenses with those of funds in both the relevant expense group and a broader group of funds, each selected and provided by Lipper. The expense comparisons compared the Feeder Fund to funds similar in size to the Fund, and the Board noted that the Feeder Funds’ assets represented a significant portion of the Fund’s assets. The Board noted that each Feeder Fund’s expense information reflected both management fees and total expenses payable by the Feeder Fund as well as management fees and total expenses payable by the Fund, and therefore was relevant to the Board’s conclusions regarding the Fund’s expenses. The Board also reviewed information regarding fees charged by the Manager to other U.S. clients investing primarily in an asset class similar to that of the Fund, including, where applicable, separate accounts.

The Manager reviewed with the Board the differences in scope of services provided to the Fund and to these other clients, noting that the Fund is provided with administrative services, office facilities, Fund officers (including the Fund’s chief executive, chief financial and chief compliance officers), and that the Manager coordinates and oversees the provision of services to the Fund by other Fund service providers. The Board considered the fee comparisons in light of the differences required to manage these different types of accounts. The Board also considered and discussed information about the Subadvisers’ fees, including the amount of the management fees retained by the Manager after payment of the subadvisory fee. The Board also received an analysis of complex-wide management fees provided by the Manager, which, among other things, set out a framework of fees based on asset classes.

Management also discussed with the Board the Fund’s placement agency arrangements and the distribution arrangements of the Feeder Funds. The Board noted that beneficial interests in the Fund are issued solely in private placement transactions that do not involve any “public offering” within the meaning of Section 4(2) of the Securities Act of 1933, as amended, and that the placement agent for the Fund receives no compensation for serving in that capacity. The Board also was provided with information concerning revenues received by and certain expenses incurred by distributors affiliated with the Fund during the past two years and how the amounts received by the distributors were paid during that period.

The information comparing each Feeder Fund’s Contractual Management Fee and its Actual Management Fee (which reflects a fee waiver) as well as its actual total expense ratio to its Lipper expense group, consisting of a group (including

Tax Free Reserves Portfolio  |  55

Board approval of management and
subadvisory agreements (unaudited) continued

the Feeder Fund) of either retail no-load funds classified as “tax exempt money market funds” or funds classified as “institutional tax exempt money market funds” and chosen to be comparable to the Feeder Fund by Lipper, showed that Citi Tax Free Reserves’ Contractual Management Fee was slightly above the median of the management fees paid by the other funds in the Lipper expense group, Citi Institutional Tax Free Reserves was slightly below the median of the management fees paid by the other funds in the Lipper expense group and that each Feeder Fund’s Actual Management Fee was below the median of its expense group. The Board noted that each Feeder Fund’s actual total expense ratio also was below the median of its expense group. The Board also noted that the Manager was continuing its voluntary waiver until further notice, resulting in the same net effective fee as currently in place, which is lower than the Fund’s current contractual management fee.

Taking all of the above into consideration, the Board determined that the management fee and the subadvisory fees for the Fund were reasonable in light of the nature, extent and quality of the services provided to the Fund under the Management Agreement and the Sub-Advisory Agreement.

Manager profitability

The Board received and considered an analysis of the profitability of the Manager and its affiliates in providing services to the Fund. The Board also received profitability information with respect to the Legg Mason Partners fund complex as a whole. In addition, the Board received information with respect to the Manager’s allocation methodologies used in preparing this profitability data, as well as a report from an outside consultant that had reviewed the methodologies. The profitability of the Manager and its affiliates was considered by the Board not excessive in light of the nature, extent and quality of the services provided to the Fund and the type of fund.

Economies of scale

The Board received and discussed information concerning whether the Manager realizes economies of scale as the Fund’s assets grow. The Board noted that each Feeder Fund’s Contractual Management Fee (which also reflects the Fund’s management fee) is slightly above or below the average of such Feeder Fund’s Lipper expense group and such Feeder Fund’s Contractual Management Fee is approximately equivalent to the asset-weighted average of the management fees paid by the funds in the Feeder Fund’s expense group at all asset levels as set forth in the information provided by Lipper. The Board also noted that the each Feeder Fund’s Actual Management Fee (which also reflects the Fund’s management fee) was below the median of its expense group. The Board also noted that as the Fund’s assets have increased over time, certain expenses, such as fees for Board members, auditors and legal fees, become a smaller percentage of overall assets. The Board also considered fee waivers by

56  |  Tax Free Reserves Portfolio

the Manager and the fact that the Manager pays the subadvisory fee out of the management fee.

The Board determined that the management fee structure for the Fund was reasonable.

Other benefits to the manager and the subadviser

The Board considered other benefits received by the Manager, the Subadviser and their affiliates as a result of their relationship with the Fund, including the opportunity to offer additional products and services to Fund shareholders.

In light of the costs of providing investment management and other services to the Fund and the ongoing commitment of the Manager and the Subadviser to the Fund, the Board considered that the ancillary benefits that the Manager and its affiliates received were reasonable.

* * *

In light of all of the foregoing, the Board determined that the continuation of each of the Management Agreement and Sub-Advisory Agreement would be in the best interests of the Fund’s shareholders and approved the continuation of such agreements for another year.
