Investment commentary

Economic review

The pace of U.S. economic activity fluctuated during the twelve months ended August 31, 2016 (the “reporting period”). Looking back, the U.S. Department of Commerce reported that third quarter 2015 U.S. gross domestic product (“GDP”)ⁱ growth was 2.0%. The U.S. Department of Commerce reported that revised fourth quarter 2015 and first quarter 2016 GDP growth moderated to 0.9% and 0.8%, respectively. The U.S. Department of Commerce’s final reading for second quarter 2016 GDP growth — released after the reporting period ended — was 1.4%. The improvement in GDP growth in the second quarter reflected an acceleration in personal consumption expenditures (“PCE”) and upturns in nonresidential fixed investment and exports.

While there was a pocket of weakness in May 2016, job growth in the U.S. was solid overall and a tailwind for the economy during the reporting period. When the period ended in August 2016, the unemployment rate was 4.9%, as reported by the U.S. Department of Labor. The percentage of longer-term unemployed declined over the period. In August 2016, 26.1% of Americans looking for a job had been out of work for more than six months, versus 26.6% when the period began.

After an extended period of maintaining the federal funds rateⁱⁱ at a historically low range between zero and 0.25%, the Federal Reserve Board (the “Fed”)ⁱⁱⁱ increased the rate at its meeting on December 16, 2015. This marked the first rate hike since 2006. In particular, the U.S. central bank raised the federal funds rate to a range between 0.25% and 0.50%. In its official statement after the December 2015 meeting, the Fed said, “The stance of monetary policy remains accommodative after this increase, thereby supporting further improvement in labor market conditions and a return to 2 percent inflation….The Committee expects that economic conditions will evolve in a manner that will warrant only gradual increases in the federal funds rate; the federal funds rate is likely to remain, for some time, below levels that are expected to prevail in the longer run.” The Fed kept rates on hold at its meeting that concluded September 21, 2016 (after the reporting period ended), as well as during the prior meetings of the year. In the Fed’s statement after the September meeting it said, “The Committee judges that the case for an increase in the federal funds rate has strengthened but decided, for the time being, to wait for further evidence of continued progress toward its objectives. The stance of monetary policy remains accommodative, thereby supporting further improvement in labor market conditions and a return to 2 percent inflation.”

As always, thank you for your confidence in our stewardship of your assets.

Sincerely,

Jane Trust, CFA

President and Chief Executive Officer

ⁱ  Gross domestic product (“GDP”) is the market value of all final goods and services produced within a country in a given period of time.

ⁱⁱ  The federal funds rate is the rate charged by one depository institution on an overnight sale of immediately available funds (balances at the Federal Reserve) to another depository institution; the rate may vary from depository institution to depository institution and from day to day.

ⁱⁱⁱ  The Federal Reserve Board (the “Fed”) is responsible for the formulation of U.S. policies designed to promote economic growth, full employment, stable prices and a sustainable pattern of international trade and payments.

Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund seeks to provide shareholders with high levels of current income exempt from federal income taxes, preservation of capital and liquidity. The Fund is a money market fund that invests in securities through an underlying mutual fund, Tax Free Reserves Portfolio (the “Portfolio”), which has the same investment objective and strategies as the Fund. Under normal market conditions, the Portfolio invests at least 80% of its assets in short-term, high-quality municipal obligations and interests in municipal obligations that pay interest that is exempt from federal income tax, including the federal alternative minimum tax (“AMT”). Municipal securities include debt obligations issued by any of the fifty states and their political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in municipal securities and other structured securities such as variable rate demand obligations (“VRDOs”)ⁱ, tender option bonds, partnership interests and swap-based securities, many of which may be issued or backed by U.S. or non-U.S. banks.

The Portfolio invests in securities that, at the time of purchase, are rated by one or more rating agencies in the highest short-term rating category (or, with respect to not more than 3% of its total assets, in the second highest category) or, if not rated, that we determined to be of equivalent quality. Under normal circumstances, the Portfolio may invest up to 20% of its assets in investments that pay interest that may be subject to regular federal income tax and/or the AMT, although for temporary or defensive purposes, the Portfolio may invest an unlimited amount in such securities.

As a retail money market fund, the Fund tries to maintain a share price of $1.00 and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments.

At Western Asset Management Company (“Western Asset”), the Fund’s and the Portfolio’s subadviser, we utilize a fixed-income team approach, with decisions derived from interaction among various investment management sector specialists. The sector teams are comprised of Western Asset’s senior portfolio management personnel, research analysts and an in-house economist. Under this team approach, management of client fixed-income portfolios will reflect a consensus of interdisciplinary views within the Western Asset organization.

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

A. Most spread sectors (non-Treasuries) posted positive returns, but generated mixed results versus equal-durationⁱⁱ Treasuries over the twelve months ended August 31, 2016. The fixed income market was volatile at times given signs of generally modest economic growth, uncertainties regarding future Federal Reserve Board (the “Fed”)ⁱⁱⁱ monetary policy, the implications of the U.K.‘s referendum to leave the European Union (“Brexit”) and a number of geopolitical issues.

Short-term Treasury yields moved higher, whereas long-term Treasury yields declined during the twelve months ended August 31,

Western Asset Select Tax Free Reserves 2016 Annual Report 1

Fund overview (cont’d)

2016. Two-year Treasury yields began the reporting period at 0.74% and ended the period at 0.80%. Their peak of 1.09% occurred on December 29, 2015 and they were as low as 0.56% on July 5, 2016. Ten-year Treasury yields were 2.21% at the beginning of the period and ended the period at 1.58%. Their peak of 2.36% was on November 9, 2015 and their low of 1.37% occurred on both July 5 and July 8, 2016.

After a prolonged period of maintaining the federal funds rate^iv at a historically low range between zero and 0.25%, the Fed increased the rate at its meeting on December 16, 2015. In particular, the U.S. central bank raised the federal funds rate to a range between 0.25% and 0.50%. In its official statement after the December 2015 meeting, the Fed said it, “…expects that economic conditions will evolve in a manner that will warrant only gradual increases in the federal funds rate; the federal funds rate is likely to remain, for some time, below levels that are expected to prevail in the longer run.” At each of its meetings thus far in 2016 (including the September 21, 2016 meeting — after the reporting period ended), the Fed kept rates on hold.

The Puerto Rico, Chicago and Illinois debt complexes continued to dominate the credit headlines in the municipal market during the twelve months ended August 31, 2016. Most notably, Puerto Rico defaulted on an array of credits, including $779 million of general obligation debt on July 1, 2016. This is significant because the debt was supposed to be payable ahead of all other Commonwealth expenditures pursuant to its Constitution. In response to the dire financial situation, Congress passed the Puerto Rico Oversight, Management and Economic Stability Act (“PROMESA”), which was signed into law by President Obama on June 30, 2016. Under PROMESA, an appointed bipartisan fiscal control board will be responsible for fiscal oversight of the Commonwealth’s finances. This board will also have an active role in restructuring $60 to $70 billion of outstanding debt. Market reaction was relatively muted, as the defaults were widely expected and there were no contagion-like effects that spread to other issuers or market sectors. While there is no timetable for completion of the debt restructuring under PROMESA, most market participants believe that it will be a very lengthy process. The Chicago and Illinois debt complexes continue to be strained primarily by political inaction and the associated uncertainty caused by fundamental differences in governing philosophy on the part of a Republican governor and a Democrat-controlled state legislature. It seems reasonable to expect continued headline driven volatility and, to a lesser extent, potentially real credit implications until a framework is established that will allow governmental finance within the state to resume operating in a normal and predictable manner.

The National Association of State Budget Officers reported that aggregate fiscal year 2016 revenues were estimated to have risen 5.5%, with expenditures increasing 3.8%. This indicates fiscal responsibility and net additions to general fund reserves on a national basis. Fiscal year 2017 revenue growth is expected to slow to 2.9%, which will require increased containment of state-wide expenditures. By and large, local debt issuers fared well due to a national unemployment rate that dipped to 4.9% in August 2016 and a continued steady growth

in real estate values that have either stabilized or increased local tax collections. Offsetting this largely positive landscape, is the fact that state and local governments remain challenged by defined benefit pension liabilities, which by various measures are underfunded by $1 to $3 trillion, significant deferred infrastructure investments, and rising health care and educational expenses. While currently manageable, these issues could become much more pronounced should overall economic conditions become less favorable. Slowing economic activity, coupled with these increasing liabilities, would likely slow or begin to reverse the gains in credit quality that that municipal market has enjoyed over the past several years.

Q. How did we respond to these changing market conditions?

A. The U.S. Securities and Exchange Commission (the “SEC”)^v rules that govern money market mutual funds will go into effect by mid-October 2016. Therefore, we remained cautious purchasing bonds on the yield curve^vi past that date amid potential Fund outflows. As such, throughout the reporting period we held a large portion of the Fund’s assets in daily and weekly VRDOs. As the short-term yield curve was essentially flat to inverted, there was also no yield incentive to go out further on the curve.

Performance review

As of August 31, 2016, the seven-day current yield for Select Shares of Western Asset Select Tax Free Reserves was 0.43% and the seven-day effective yield, which reflects compounding, was 0.43%.¹

Certain investors may be subject to the AMT, and state and local taxes will apply. Capital gains, if any, are fully taxable. Please consult your personal tax or legal adviser.

The Fund does not invest directly in securities but instead invests all of its investable assets in an underlying mutual fund, the Portfolio, which has the same investment objective and strategies, and substantially the same policies as the Fund. Unless otherwise indicated, references to the Fund include the underlying mutual fund, the Portfolio.

Yields will fluctuate. To obtain performance data current to the most recent month-end, please visit our website at www.leggmason.com/moneymarketfunds.

Absent fee waivers and/or expense reimbursements, the seven-day current yield and the seven-day effective yield for Select Shares would have been 0.26%; and the seven-day current yield and the seven-day effective yield for Investor Shares would have been 0.17%.

¹  The seven-day current yield reflects the amount of income generated by the investment during that seven-day period and assumes that the income is generated each week over a 365-day period. The yield is shown as a percentage of the investment. The seven-day effective yield is calculated similarly to the seven-day current yield but, when annualized, the income earned by an investment in the Fund is assumed to be reinvested. The effective yield typically will be slightly higher than the current yield because of the compounding effect of the assumed reinvestment.

The manager has voluntarily undertaken to limit Fund expenses. Such expense limitations may fluctuate daily and are voluntary and temporary and may be terminated by the manager at any time without notice.

You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

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

A. The municipal money market yield curve was relatively flat to inverted during the reporting period. Because of this, there were typically only small differences between the yields available from shorter-term municipal money market securities and longer-term securities. We maintained a large allocation to VRDOs in order to stay very liquid ahead of pending SEC money market rules going into effect by October 14, 2016. By the end of the reporting period, the Securities Industry and Financial Markets Association (“SIFMA”) Municipal Swap Index^vii was 0.63%, so staying in VRDOs was advantageous as the short-term yield curve became inverted. However, if the opportunity presented itself to add incremental yield, we selectively purchased bonds that met our stringent quality and liquidity requirements within a three to six-month range.

Q. Were there any regulatory updates during the Fund’s reporting period?

A. The SEC has adopted certain reforms to the rules that govern money market funds (the “Reforms”). Under the Reforms, the Fund will be allowed to continue to use the special pricing and valuation conventions that currently facilitate a constant share price of $1.00 if it meets the requirements of a retail money market fund. To meet these requirements, only accounts beneficially owned by natural persons (retail investors) may be invested in the Fund. The shares of any investor who does not qualify as a retail investor will be redeemed involuntarily by the Fund on September 30, 2016. Shareholders who are subject to involuntary redemption received a separate notification from the Fund. In addition, no later than October 14, 2016, the Fund may impose fees upon the sale of shares or temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.

Thank you for your investment in Western Asset Select Tax Free Reserves. As always, we appreciate that you have chosen us to manage your assets and we remain focused on seeking to achieve the Fund’s investment goals.

Sincerely,

Fund expenses (unaudited)

Example

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees; service and/or distribution (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 March 1, 2016 and held for the six months ended August 31, 2016.

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”.

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. 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.

Western Asset Select Tax Free Reserves 2016 Annual Report 13

Notes to financial statements

1. Organization and significant accounting policies

Western Asset Select Tax Free Reserves (formerly Western Asset Institutional Tax Free Reserves) (the “Fund”) is a separate non-diversified investment series of Legg Mason Partners Institutional Trust (the “Trust”). The Trust, a Maryland statutory trust, is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Fund invests all of its investable assets in Tax Free Reserves Portfolio (the “Portfolio”), a separate investment series of Master Portfolio Trust, that has the same investment objective as the Fund.

The financial statements of the Portfolio, including the schedule of investments, are contained elsewhere in this report and should be read in conjunction with the Fund’s financial statements.

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. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation. The Fund records its investment in the Portfolio at value. The value of such investment in the Portfolio reflects the Fund’s proportionate interest (86.3% at August 31, 2016) in the net assets of the Portfolio.

GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. The disclosure and valuation of securities held by the Portfolio are discussed in Note 1(a) of the Portfolio’s Notes to Financial Statements, which are included elsewhere in this report.

(b) Investment transactions and investment income. Net investment income of the Portfolio is allocated pro rata, based on respective ownership interests, among the Fund and other investors in the Portfolio (the “Holders”) at the time of such determination. Gross realized gains and/or losses of the Portfolio are allocated to the Holders in a manner such that, the net asset values per share of each Holder, after each such allocation is closer to the total of all Holders’ net asset values divided by the aggregate number of shares outstanding for all Holders. The Fund also pays certain other expenses which can be directly attributed to the Fund.

(c) Distributions to shareholders. Distributions from net investment income on the shares of the Fund are declared each business day and are paid monthly. The Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from federal and certain state income taxes, to retain such tax-exempt status when distributed to the shareholders of the Fund. Distributions of net realized gains, if any, are taxable and are declared at least annually. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

14 Western Asset Select Tax Free Reserves 2016 Annual Report

(d) Share class accounting. Investment income, common expenses and realized gains (losses) 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 share class.

(e) 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 (the “Code”), as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund’s financial statements.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of August 31, 2016, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

Dividends paid by the Fund from net interest received on tax-exempt money market instruments are not includable by shareholders as gross income for federal income tax purposes because the Fund intends to meet certain requirements of the Internal Revenue Code applicable to regulated investment companies, including Subchapter M, which will enable the Fund to pay exempt-interest dividends. The portion of such interest, if any, earned on private activity bonds issued after August 7, 1986, may be considered a tax preference item to shareholders.

(f) Reclassification. GAAP requires that certain components of net assets be reclassified 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)	$	(104,600)	$	2,228	$	102,372

^(a)  Reclassifications are due primarily due to the tax-exempt income retained by the Fund and the expiration of a capital loss carryforward.

2. Investment management agreement and other transactions with affiliates

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

Western Asset Select Tax Free Reserves 2016 Annual Report 15

Notes to financial statements (cont’d)

Under the investment management agreement, the Fund pays an investment management fee at an annual rate that decreases as assets increase, as follows:

Average Daily Net Assets	Annual Rate
First $1 billion		0.250	%
Next $1 billion		0.225
Next $3 billion		0.200
Next $5 billion		0.175
Over $10 billion		0.150

Since the Fund invests all of its investable assets in Tax Free Reserves Portfolio, the investment management fee of the Fund will be reduced by the investment management fee allocated to the Fund by Tax Free Reserves Portfolio.

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

As a result of an expense limitation arrangement between the Fund and LMPFA, the ratio of total annual fund operating expenses, other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets of Select Shares (formerly Institutional Shares) and Investor Shares did not exceed 0.20% and 0.35%, respectively. These expense limitation arrangements cannot be terminated prior to December 31, 2017 without the Board of Trustees’ consent. Additional amounts may be voluntarily waived and/or reimbursed from time to time.

During the year ended August 31, 2016, fees waived and/or expenses reimbursed amounted to $2,513,083.

LMPFA is permitted to recapture amounts waived and/or reimbursed to a class during the same fiscal year if the class’ total annual operating expenses have fallen to a level below the expense limitation (“expense cap”) in effect at the time the fees were earned or the expenses incurred. In no case will LMPFA recapture any amount that would result, on any particular business day of the Fund, in the class’ total annual operating expenses exceeding the expense cap or any other lower limit then in effect.

Legg Mason Investor Services, LLC, a wholly-owned broker-dealer subsidiary of Legg Mason, serves as the Fund’s sole and exclusive distributor.

All officers and one Trustee of the Trust are employees of Legg Mason or its affiliates and do not receive compensation from the Trust.

During the year ended August 31, 2015, LMPFA voluntarily made a capital contribution to the Fund in the amount of $58,728. This contribution was made to reimburse the Fund for previous realized losses experienced by the Fund. LMPFA did not receive any shares of the Fund or other consideration in exchange for making this cash contribution.

3. Class specific expenses, waivers and/or expense reimbursements

The Fund has adopted a Rule 12b-1 distribution and service plan under the 1940 Act, and under that plan the Fund pays a service and/or distribution fee with respect to its Investor

16 Western Asset Select Tax Free Reserves 2016 Annual Report

shares calculated at the annual rate of 0.10% of the average daily net assets. Service and/or distribution fees are accrued daily and paid monthly.

For the year ended August 31, 2016, class specific expenses were as follows:

	Service and/or Distribution Fees			Transfer Agent Fees
Select Shares1		—		$	50,463
Investor Shares	$	124,396	2		2,467
Total	$	124,396		$	52,930

¹  Prior to August 26, 2016, Select Shares were known as Institutional Shares.

²  Amount shown is exclusive of waivers. The service and/or distribution fees waived for the year ended August 31, 2016 amounted to $100,138 for Investor Shares. Such waiver is voluntary and may be reduced or terminated at any time.

For the year ended August 31, 2016, waivers and/or expense reimbursements by class were as follows:

	Waivers/Expense Reimbursements
Select Shares1	$	2,162,011
Investor Shares		351,072
Total	$	2,513,083

¹  Prior to August 26, 2016, Select Shares were known as Institutional Shares.

4. Distributions to shareholders by class

	Year Ended August 31, 2016		Year Ended August 31, 2015
Net Investment Income:
Select Shares1	$	1,366,647	$	107,563
Investor Shares		120,192		8,756
Total	$	1,486,839	$	116,319

¹  Prior to August 26, 2016, Select Shares were known as Institutional Shares.

5. Shares of beneficial interest

At August 31, 2016, the Trust had an unlimited number of shares of beneficial interest authorized with a par value of $0.00001 per share. The Fund has the ability to issue multiple classes of shares. Each class of shares represents an identical interest and has the same rights, except that each class bears certain direct expenses, including those specifically related to the distribution of its shares.

Transactions in shares of each class were as follows:

	Year Ended August 31, 2016		Year Ended August 31, 2015
Select Shares1
Shares sold		2,256,883,603		1,535,613,136
Shares issued on reinvestment		702,026		44,467
Shares repurchased		(2,230,583,865)		(1,500,002,868)
Shares issued with merger		—		461,780,255
Net increase		27,001,764		497,434,990

Western Asset Select Tax Free Reserves 2016 Annual Report 17

Notes to financial statements (cont’d)

	Year Ended August 31, 2016		Year Ended August 31, 2015
Investor Shares
Shares sold		211,320,016		190,399,167
Shares issued on reinvestment		116,394		8,409
Shares repurchased		(202,008,443)		(186,093,877)
Shares issued with merger		—		79,423,484
Net increase		9,427,967		83,737,183

¹  Prior to August 26, 2016, Select Shares were known as Institutional Shares.

Because the Fund has maintained a $1.00 net asset value per share from inception, the number of shares sold, shares issued on reinvestment of dividends declared, and shares repurchased, is equal to the dollar amount shown in the Statements of Changes in Net Assets for the corresponding fund share transactions.

6. Transfer of net assets

On July 24, 2015, the Fund acquired the assets and liabilities of the Western Asset Institutional AMT Free Municipal Money Market Fund (the “Acquired Fund”). Total shares issued by the Fund and the total net assets of the Acquired Fund and the Fund on the date of the transfer were as follows:

Acquired Fund	Shares Issued by the Fund		Total Net Assets of the Acquired Fund		Total Net Assets of the Fund
Western Asset Institutional AMT Free Municipal Money Market Fund		541,203,739	$	541,203,739	$	600,044,280

Under the reorganization, for each share held, shareholders of the Acquired Fund’s Institutional Shares and Investor Shares received 1 share of the Fund’s Select Shares (formerly Institutional Shares) and Investor Shares, respectively.

The total net assets of the Acquired Fund before acquisition included accumulated net realized loss of $146,862. Total net assets of the Fund immediately after the transfer were $1,141,248,019. The transaction was structured to qualify as a tax-free reorganization under the Internal Revenue Code of 1986, as amended.

Proforma results of operations of the combined entity for the entire year ended August 31, 2015, as though the acquisition had occurred as of the beginning of the year (rather than on the actual acquisition date), are as follows:

Net investment income	$	333,642
Increase in net assets from operations	$	333,642

Because the combined investment portfolios have been managed as a single portfolio since the acquisition was completed, it is not practicable to separate the amounts of revenue and earnings of the Acquired Fund that were included in the Fund’s Statement of Operations since the close of business on July 24, 2015.

18 Western Asset Select Tax Free Reserves 2016 Annual Report

7. Income tax information and distributions to shareholders

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

	2016		2015
Distributions paid from:
Tax-exempt income	$	1,479,308	$	116,319
Ordinary income		7,531		—
Total distributions paid	$	1,486,839	$	116,319

As of August 31, 2016, there were no significant differences between the book and tax basis components of net assets.

As of August 31, 2016, the Fund had capital losses of $6,846 that have been deferred in the current year as either short-term or long-term losses. These losses will be deemed to arise on the first day of the next taxable year in the same character as they were originally deferred and will be available to offset future taxable capital gains. These losses must be utilized before any of the Fund’s capital loss carryforward may be utilized.

Additionally, as of August 31, 2016, the Fund had the following net capital loss carryforwards remaining:

Year of Expiration	Amount
8/31/2017	$	(25,906	)
8/31/2018		(4,808	)
8/31/2019		(104	)
	$	(30,818	)

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

8. Money market fund reform

The U.S. Securities and Exchange Commission has adopted certain reforms to the rules that govern money market funds (the “Reforms”). Under the Reforms, the Fund will be allowed to continue to use the special pricing and valuation conventions that currently facilitate a constant share price of $1.00 if it meets the requirements of a retail money market fund. To meet these requirements, only accounts beneficially owned by natural persons (retail investors) may be invested in the Fund. The shares of any investor who does not qualify as a retail investor will be redeemed involuntarily by the Fund on September 30, 2016. Shareholders who are subject to involuntary redemption received a separate notification from the Fund. In addition, no later than October 14, 2016, the Fund may impose fees upon the sale of shares or temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.

9. Subsequent event

Subsequent to the year ended August 31, 2016, shareholder redemptions from Select Shares and Investor Shares exceeded 50% of Select Shares and Investor Shares net assets as of August 31, 2016.

We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Western Asset Select Tax Free Reserves as of August 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years or period in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

46 Tax Free Reserves Portfolio 2016 Annual Report

Notes to financial statements

1. Organization and significant accounting policies

Tax Free Reserves Portfolio (the “Portfolio”) is a separate non-diversified investment series of Master Portfolio Trust (the “Trust”). The Trust, a Maryland statutory trust, is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Declaration of Trust permits the Trustees to issue beneficial interests in the Portfolio. At August 31, 2016, all investors in the Portfolio were funds advised or administered by the manager of the Portfolio 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. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation. In accordance with Rule 2a-7 under the 1940 Act, money market instruments are valued at amortized cost, 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 its compliance with certain conditions as specified by Rule 2a-7 under the 1940 Act.

The Board of Trustees is responsible for the valuation process and has delegated the supervision of the daily valuation process to the Legg Mason North Atlantic Fund Valuation Committee (the “Valuation Committee”). The Valuation Committee, pursuant to the policies adopted by the Board of Trustees, is responsible for making fair value determinations, evaluating the effectiveness of the Portfolio’s pricing policies, and reporting to the Board of Trustees.

The Portfolio uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

• Level 1 — quoted prices in active markets for identical investments

• Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3 — significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

Tax Free Reserves Portfolio 2016 Annual Report 47

Notes to financial statements (cont’d)

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets carried at fair value:

ASSETS
Description	Quoted Prices (Level 1)		Other Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Short-Term Investments†		—	$	1,300,345,631		—	$	1,300,345,631

† See Schedule of Investments for additional detailed categorizations.

(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) Method of allocation. Net investment income of the Portfolio is allocated pro rata, based on respective ownership interests, among the Fund and other investors in the Portfolio (the “Holders”) at the time of such determination. Gross realized gains and/or losses of the Portfolio are allocated to the Holders in a manner such that, the net asset values per share of each Holder, after each such allocation is closer to the total of all Holders’ net asset values divided by the aggregate number of shares outstanding for all Holders.

(d) Credit and market risk. The Portfolio 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. Demand features are often issued by third party financial institutions, generally domestic and foreign banks, and by brokerage firms or insurance companies. Frequently, floating rate and variable rate obligations are secured by letters of credit or other credit support arrangements provided by banks. Accordingly, the credit quality and liquidity of the Portfolio’s investments may be dependent in part on the credit quality of the institutions supporting the Portfolio’s investments and changes in the credit quality of these institutions could cause losses to the Portfolio and affect its share price. 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.

(e) Compensating balance arrangements. The Portfolio has an arrangement with its custodian bank whereby a portion of the custodian’s fees is paid indirectly by credits earned on the Portfolio’s cash on deposit with the bank.

(f) 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 Subchapter M of the Internal Revenue Code.

Management has analyzed the Portfolio’s tax positions taken on income tax returns for all open tax years and has concluded that as of August 31, 2016, no provision for income tax is required in the Portfolio’s financial statements. The Portfolio’s federal and state income tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

(g) 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 an investment management fee, 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.

LMPFA has voluntarily agreed to waive and/or reimburse 0.15% of Portfolio expenses. This arrangement may be reduced or terminated under certain circumstances. Additional amounts may be voluntarily waived and/or reimbursed from time to time.

During the year ended August 31, 2016, fees waived and/or expenses reimbursed amounted to $2,014,834.

LMPFA is permitted to recapture amounts waived and/or reimbursed to the Portfolio during the same fiscal year under certain circumstances.

All officers and one Trustee of the Trust are employees of Legg Mason or its affiliates and do not receive compensation from the Trust.

The Portfolio is permitted to purchase or sell securities from or to certain other affiliated funds or portfolios under specified conditions outlined in procedures adopted by the Board of Trustees. The procedures have been designed to provide assurance that any purchase or

Notes to financial statements (cont’d)

sale of securities by the Fund from or to another fund or portfolio that is, or could be considered, an affiliate by virtue of having a common investment manager or subadviser (or affiliated investment manager or subadviser), common Trustees and/or common officers complies with Rule 17a-7 under the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. For the year ended August 31, 2016, such purchase and sale transactions were $1,511,840,032 and $1,197,156,697, respectively.

3. Investments

On July 24, 2015, Western Asset Institutional AMT Free Municipal Money Market Fund transferred all of its investable assets, with a value of $540,906,314 to the Portfolio in exchange for an interest in the Portfolio. In addition, Western Asset Institutional AMT Free Municipal Money Market Fund transferred cash of $18,698 and interest receivables of $304,666. The transaction was structured to qualify as a tax free exchange of assets into a partnership.

4. Derivative instruments and hedging activities

During the year ended August 31, 2016, the Portfolio did not invest in derivative instruments.

5. Money market fund reform

The U.S. Securities and Exchange Commission has adopted certain reforms to the rules that govern money market funds (the “Reforms”). Under the Reforms, the Portfolio will be allowed to continue to use the special pricing and valuation conventions that allow its feeder funds to facilitate a constant share price of $1.00 if it meets the requirements of a retail money market fund. To meet these requirements, only accounts beneficially owned by natural persons (retail investors) may be invested in the Holders of interests of the Portfolio. The Portfolio may consider itself a retail money market fund if all of its feeder funds are qualified retail money market funds and have policies and procedures in place to ensure that all shares of each feeder fund are beneficially owned by natural persons. In addition, no later than October 14, 2016, the Portfolio may impose fees upon the withdrawal of interests or temporarily suspend the withdrawal of interests if the Portfolio’s liquidity falls below required minimums because of market conditions or other factors. The Reforms require that feeder funds pass through to their investors such fees or gate imposed by a master fund in which a fund invests.

Report of independent registered public accounting firm

The Board of Trustees and Investors

Master Portfolio Trust:

We have audited the accompanying statement of assets and liabilities of Tax Free Reserves Portfolio (the “Portfolio”), a series of Master Portfolio Trust, including the schedule of investments, as of August 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended. These financial statements and financial highlights are the responsibility of the Portfolio’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits 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 and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of August 31, 2016, by correspondence with the custodian and broker or by other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Tax Free Reserves Portfolio as of August 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

(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 LMPFA 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.

Legg Mason Partners Institutional Trust’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.
