The Fund
   Western Asset/Claymore U.S. Treasury Inflation Protected Securities Fund
("WIA" or the "Fund") is a closed-end, diversified management investment
company which seeks to provide current income for its shareholders. Capital
appreciation, when consistent with current income, is a secondary investment
objective. Substantially all of the net investment income is distributed to the
shareholders. A Dividend Reinvestment Plan is available to those shareholders
of record desiring it. The shares are listed on the New York Stock Exchange
where they are traded under the symbol WIA.

Investment Policies
   The Fund's investment policies include, among others, that its portfolio be
invested as follows:

   .  At least 80% of total managed assets in U.S. Treasury Inflation Protected
      Securities.

   .  Up to 20% of total managed assets in corporate bonds or other securities
      and instruments.

   .  Preferred shares, together with other forms of leverage (including
      reverse repurchase agreements and dollar roll transactions), will not
      exceed 38% of the Fund's total managed assets.

Dividend Reinvestment Plan
   The Fund and EquiServe Trust Company N.A. ("Agent"), as the Transfer Agent
and Registrar of WIA, offer a convenient way to add shares of WIA to your
account. WIA offers to all common shareholders a Dividend Reinvestment Plan
("Plan"). Under the Plan, cash distributions (e.g., dividends and capital
gains) on the common shares are automatically invested in shares of WIA unless
the shareholder elects otherwise.

   As a participant in the Dividend Reinvestment Plan, you will automatically
receive your dividend or net capital gains distribution in newly issued shares
of WIA, if the market price of the shares on the date of the distribution is at
or above the net asset value ("NAV") of the shares, minus estimated brokerage
commissions that would be incurred upon the purchase of common shares on the
open market. The number of shares to be issued to you will be determined by
dividing the amount of the cash distribution to which you are entitled (net of
any applicable withholding taxes) by the greater of the NAV per share on such
date or 95% of the market price of a share on such date. If the market price of
a share on such distribution date is below the NAV, minus estimated brokerage
commissions that would be incurred upon the purchase of common shares on the
open market, the Agent will, as agent for the participants, buy shares of WIA
through a broker on the open market. All common shares acquired on your behalf
through the Plan will be automatically credited to an account maintained on the
books of the Agent.

Additional Information Regarding the Plan
   WIA will pay all costs applicable to the Plan, with the exceptions noted
below. Brokerage commissions for open market purchases by the Agent under the
Plan will be charged to participants. All shares acquired through the Plan
receive voting rights and are eligible for any stock split, stock dividend, or
other rights accruing to shareholders that the Board of Trustees may declare.

   You may terminate participation in the Plan at any time by giving written
notice to the Agent. Such termination shall be effective prior to the record
date next succeeding the receipt of such instructions or by a later date of
termination specified in such instructions. Upon termination, a participant may
request a certificate for the full shares credited to his or her account or may
request the sale of all or part of such shares. Fractional shares credited to a
terminating account will be paid for in cash at the current market price at the
time of termination.

                                      1

Annual Report to Shareholders

   Dividends and other distributions invested in additional shares under the
Plan are subject to income tax just as if they had been received in cash. After
year end, dividends paid on the accumulated shares will be included in the Form
1099-DIV information return to the Internal Revenue Service (IRS) and only one
Form 1099-DIV will be sent to participants each year.

   Inquiries regarding the Plan, as well as notices of termination, should be
directed to EquiServe Trust Company, N.A., P.O. Box 43011, Providence, Rhode
Island 02940-3011--Investor Relations telephone number (800) 426-5523.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE


General Market Performance
   The U.S. economy continued to display impressive signs of strength in the
fourth quarter of 2003. Although the pace of retail sales appears to have
cooled a bit since the third quarter, manufacturing and housing remained quite
strong and the labor market continued to firm. Good economic news, coupled with
strong productivity and improving earnings, helped drive equity prices higher.
Inflation pressures continued to increase in December as the dollar fell, gold
rose, commodities surged, and oil prices edged higher. Despite signs of
stronger economic activity and rising prices, headline and core CPI inflation
registered declines in November, and bond yields declined modestly.

   With economic news still strong but not blazing strong, and with the Fed
continuing to insist that a tightening is far out on the horizon, intermediate
nominal yields fell 20 basis points/A/ ("bps") or so, while long-term yields
fell by only 5 bps. This same pattern--a modest steepening of the yield
curve--was repeated in the Treasury Inflation-Protected Securities ("TIPS")
market as real yields also declined. Breakeven spreads were little changed for
December, although they hovered near relatively high levels as inflation
concerns continued to manifest themselves. TIPS received a tiny negative
inflation adjustment for the month, repeating what appears to be a regular
seasonal pattern.

Fund Performance
   The Fund recorded a total return, based on market value per share, of +1.58%
since its inception. During this time period, the stock price has remained
stable in a range from $14.92 to $15.70. Since the Fund began on September 30,
2003, there have been three common dividends declared and two paid. No
Preferred Dividends were recorded as of 12/31/03. The next common dividend pay
date is January 9, 2004.

   The pie chart above represents the Fund's portfolio as of December 31, 2003.
The Fund's portfolio is actively managed, and its portfolio composition, credit
quality breakdown, and other portfolio characteristics will vary from time to
time. U.S. Treasury Inflation Protected Securities are unrated, but are backed
by the full faith and credit of the United States and are therefore considered
by the Fund's investment adviser to be comparable to bonds rated AAA/Aaa.

Annual Report to Shareholders

NOTES TO FINANCIAL STATEMENTS
(Amounts in Thousands)

1. Significant Accounting Policies:

   Western Asset/Claymore U.S. Treasury Inflation Protected Securities Fund
(the "Fund") is registered under the Investment Company Act of 1940 ("1940
Act"), as amended, as a diversified, closed-end management investment company.
The Fund commenced operations on September 30, 2003.

   The Fund's primary investment objective is to provide current income for its
shareholders. Capital appreciation, when consistent with current income, is a
secondary investment objective.

   The following is a summary of significant accounting policies followed by
the Fund in the preparation of its financial statements.

Security Valuation

   Securities owned by the Fund for which market quotations are readily
available are valued at current market value. Current market value means the
last sale price of the day or, in the absence of any such sales, the bid price
obtained from quotation reporting systems, pricing services or other approved
methods. Other assets and securities for which no quotations are readily
available are valued at fair value as determined in good faith by the Board of
Trustees or persons acting under their supervision. The factors considered in
making such valuations are subject to change over time and are reviewed
periodically. The values assigned to fair valued investments are based on
available information and do not necessarily represent amounts that might
ultimately be realized, since such amounts depend on future developments
inherent in long-term investments. Further, because of the inherent uncertainty
of valuation, such estimated values may differ significantly from the values
that would have been used had a ready market for the investments existed, and
the differences could be material. Securities with remaining maturities of 60
days or less are generally valued at a readily available market price or, if a
market price is not readily available, fair valued at amortized cost.

   Where a security is traded on more than one market, the securities are
generally valued on the market considered by the Fund's adviser to be the
primary market.

Security Transactions

   Security transactions are recorded on the trade date. Realized gains and
losses from security transactions are reported on an identified cost basis for
both financial reporting and federal income tax purposes.

   Purchases and sales of investment securities (excluding short-term
investments, U.S. government securities and U.S. government agencies)
aggregated $90,803 and $0, respectively, for the period ended December 31,
2003. Purchases and sales of U.S. government and government agency obligations
were $509,399 and $12,650, respectively, for the period December 31, 2003.

Repurchase Agreements

   The Fund may engage in repurchase agreement transactions. Under the terms of
a typical repurchase agreement, a fund takes possession of an underlying debt
obligation subject to an obligation of the seller to repurchase, and a fund to
resell, the obligation at an agreed-upon price and time, thereby determining
the yield during a fund's holding period. This arrangement results in a fixed
rate of return that is not subject to market fluctuations during the fund's
holding period. The value of the collateral is at all times at least equal to
the total amount of the repurchase obligation, including interest. In the event
of counterparty default, a fund has the right to use the collateral to satisfy
the terms of the repurchase agreement. However, there could be potential loss
to the fund in the event the fund is delayed or prevented from exercising its
right to dispose of the collateral securities, including the risk of a possible
decline in the value of the collateral securities during the period in which
the fund seeks to assert its rights. The Fund's investment adviser reviews the
value of the collateral and the creditworthiness of those banks and dealers
with which the Fund enters into repurchase agreements to evaluate potential
risks.

                                      14




Options, Futures and Swap Agreements

 The current market value of an exchange traded option is the last sale price
or, in the absence of a sale, the price obtained by reference to broker-dealer
quotations. Futures contracts are valued daily at the settlement price
established by the board of trade or exchange on which they are traded. Futures
contracts are marked-to-market on a daily basis. As the contract's value
fluctuates, payments known as variation margin are made to or received from the
futures commission merchant. Swap agreements are priced daily based upon
quotations from brokers and the change, if any, is recorded as unrealized
appreciation or depreciation.

Short Sales

   The Fund may sell a security it does not own in anticipation of a decline in
the market price of that security. The Fund must then borrow the security sold
short and deliver it to the dealer that brokered the short sale. A gain,
limited to the price at which the security was sold short, or a loss,
potentially unlimited in size, will be recognized upon the termination of the
short sale. With respect to each short sale, the Fund must maintain collateral
in a segregated account consisting of liquid assets with a value at least equal
to the current market value of the shorted securities, marked-to-market daily,
or take other actions permitted by law to cover its obligations. Dividend
expenses and fees paid to brokers to borrow securities in connection with short
sales are considered part of the cost of short sale transactions.

Distributions to Common Shareholders

 Net investment income for dividend purposes is recorded on the accrual basis
and consists of interest and dividends less expenses. All premiums and
discounts are amortized for financial reporting and tax purposes using the
effective interest method over the period to maturity of the security, and
serve to reduce or increase interest income. Dividend income is recorded on the
ex-dividend date. Dividends from net investment income are paid monthly.
Distributions are determined in accordance with income tax regulations, which
may differ from accounting principles generally accepted in the United States
of America; accordingly, periodic reclassifications are made within the Fund's
capital accounts to reflect income and gains available for distribution under
tax regulations.

Use of Estimates

   The preparation of the financial statements in accordance with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual results could differ from
these estimates.

2. Federal Income Taxes:

   No provision for federal income or excise taxes is required since the Fund
intends to qualify as a regulated investment company and distribute
substantially all of its taxable income and capital gain to its shareholders.
Because federal income tax regulations differ from accounting principles
generally accepted in the United States of America, income and capital gain
distributions determined in accordance with tax regulations may differ from net
investment income and realized gains recognized for financial reporting
purposes. Accordingly, the character of distributions and composition of net
assets for tax purposes differs from those reflected in the accompanying
financial statements.

   Distributions of $4,656 during the year ended December 31, 2003, were
characterized as ordinary income. No capital gain distributions were paid
during the year ended December 31, 2003.

   Pursuant to federal income tax regulations applicable to investment
companies, the Fund has elected to treat net capital losses realized between
November 1 and December 31 of each year ("post-October loss") as occurring on
the first day of the following tax year. For the year ended December 31, 2003,
realized capital and currency losses reflected in the accompanying financial
statements, which will not be recognized for federal income tax purposes until
2004, are shown in the table below.

                                      15

Annual Report to Shareholders

NOTES TO FINANCIAL STATEMENTS--Continued


   The tax basis components of net assets at December 31, 2003, were:


                                                        
           Unrealized appreciation                         $  4,296
           Unrealized depreciation                             (663)
                                                           --------
           Net unrealized appreciation/(depreciation)         3,633
           Undistributed ordinary income                        943
           Capital loss carryforwards                          (478)
           Post-October loss push and other loss deferrals   (1,482)
           Paid-in capital                                  410,594
                                                           --------
           Net assets                                      $413,210
                                                           ========


   The difference between book and tax basis unrealized
appreciation/(depreciation) is primarily due to the tax deferral of wash sale
losses and tax treatment of market discount on certain debt instruments.

   The Fund intends to retain realized capital gains that may be offset against
available capital loss carryforwards for federal income tax purposes. As of
December 31, 2003, the Fund had capital loss carryforwards of $478, expiring in
2011.

   At December 31, 2003, the cost of investments for federal income tax
purposes was $621,022.

3. Financial Instruments:

Options Transactions

   A call option gives the option holder the right to purchase the underlying
security at a specified price until a specified date. A put option gives the
option holder the right to sell the underlying security at a specified price
until a specified date. The risk in writing a covered call option is that the
Fund may forgo the opportunity for profit if the market price of the underlying
security increases and the option is exercised. The risk in writing a put
option is that the Fund may incur a loss if the market price of the underlying
security decreases and the option is exercised. In addition, there is a risk
that the Fund may not be able to enter into a closing transaction because of an
illiquid secondary market or, for over-the-counter options, because of the
counterparty's inability to perform. Activity in written call and put options
during the period was as follows:

Swap Agreements

   The use of swaps involves risks that are different from those associated
with ordinary portfolio securities transactions. Swap agreements may be
considered to be illiquid. Although the Fund will not enter into any swap
agreement unless the Adviser believes that the other party to the transaction
is creditworthy, the Fund does bear the risk of loss of the amount expected to
be received under the swap agreement in the event of the default or bankruptcy
of the agreement counterparty. The Fund had no open swap agreements at December
31, 2003.

                                      16




Futures

   Upon entering into a futures contract, the Fund is required to deposit with
the broker an amount of cash or cash equivalents equal to a percentage of the
contract amount. This is known as the "initial margin." Subsequent payments
("variation margin") are made or received by the Fund each day, depending on
the daily fluctuation in the value of the contract. The daily changes in
contract value are recorded as unrealized gains or losses and the Fund
recognizes a gain or loss when the contract is closed.

   The Fund may enter into futures contracts in connection with its interest
rate management strategy or for other purposes. Risks arise from the possible
illiquidity of the futures market and from the possibility that a change in the
value of a contract may not correlate with changes in interest rates, if
applicable. The Fund had no open futures positions at December 31, 2003.

Reverse Repurchase Agreements

   The Fund may enter into reverse repurchase agreements. Under the terms of a
typical reverse repurchase agreement, a fund sells a security subject to an
obligation to repurchase the security from the buyer at an agreed-upon time and
price, thereby determining the yield to the buyer during the buyer's holding
period. A reverse repurchase agreement involves the risk, among others, that
the market value of the collateral retained by the fund may decline below the
price of the securities the fund has sold but is obligated to repurchase under
the agreement. In the event the buyer of securities under a repurchase
agreement files for bankruptcy or becomes insolvent, the fund's use of the
proceeds of the agreement may be restricted pending a determination by the
party, or its trustee or receiver, whether to enforce the fund's obligation to
repurchase the securities. In entering into reverse repurchase agreements, the
fund will maintain cash, U.S. government securities or other liquid high grade
debt obligations at least equal in value to its obligations with respect to
reverse repurchase agreements or take other actions permitted by law to cover
its obligations.

   At the time the Fund enters into a reverse repurchase agreement, it will
segregate, on its books, cash, U.S. government securities or other liquid high
grade debt obligations having a value at least equal to the repurchase price or
take other actions permitted by law to cover its obligations. For the period
ended December 31, 2003, the average amount of reverse repurchase agreements
outstanding was $148,153 and the daily weighted average interest rate was 1.03%.

   As of December 31, 2003, the Fund entered into a reverse repurchase
agreement (the "Reverse Repurchase Agreement") with Lehman Brothers, Inc.
("Lehman") for $25,000, which was settled on January 6, 2004. The Reverse
Repurchase Agreement was recorded at cost and was fully collateralized by a
U.S. Treasury Inflation Protected Security with a market value of $30,019, and
a carrying value of $30,000 that matures on January 15, 2011. The implied
interest rate on the Reverse Repurchase Agreement was 0.98%. The Fund
immediately and subsequently invested the proceeds in a repurchase agreement
(the "Repurchase Agreement") with Lehman for $25,000, which agreement was
settled on January 6, 2004. The Repurchase Agreement was recorded at cost and
was fully collateralized by a U.S. Treasury Inflation Protected Security with a
fair value of $30,327, and a carrying value of $30,313 that matures on January
15, 2011. The implied interest rate on the Repurchase Agreement was 1.03%.

   As of December 31, 2003, the Fund entered into another reverse repurchase
agreement (the "Reverse Repurchase Agreement") with Lehman for $50,000, which
was settled on January 6, 2004. The Reverse Repurchase Agreement was recorded
at cost and was fully collateralized by a U.S. Treasury Inflation Protected
Security with a fair value of $59,154, and a carrying value of $59,125 that
matures on January 15, 2012. The implied interest rate on the Reverse
Repurchase Agreement was 0.98%. The Fund immediately and subsequently invested
the proceeds in a repurchase agreement (the "Repurchase Agreement") with Lehman
for $50,000, which agreement was settled on January 6, 2004. The Repurchase
Agreement was recorded at cost and was fully collateralized by a U.S. Treasury
Inflation Protected Security with a fair value of $58,537, and a carrying value
of $58,500 that matures on January 15, 2011. The implied interest rate on the
Repurchase Agreement was 1.03%.

   The net result of this transaction is presented, on the statement of Assets
and Liabilities as a component of interest and dividend receivable.

2003. Under the Investment Company Act of 1940, the Fund may not declare
dividends or make other distributions on common shares or purchase any such
shares if, at the time of declaration, distribution or purchase, asset coverage
with respect to the outstanding Preferred Shares would be less than 200%.

   The Preferred Shares are redeemable at the option of the Fund, in whole or
in part, on any dividend payment date at $25,000 per share plus any accumulated
but unpaid dividends. The Preferred Shares are also subject to mandatory
redemption at $25,000 per share plus any accumulated but unpaid dividends,
whether or not earned or declared, if certain requirements relating to the
composition of the assets and liabilities of the Fund as set forth in the
Bylaws are not satisfied.

   Preferred shareholders, who are entitled to one vote per Preferred Share,
generally vote as a single class with the common shareholders, but will vote
separately as a class (and, in certain circumstances, vote separately by
series) with respect to certain matters set forth in the Bylaws. The preferred
shareholders are entitled to elect two Trustees of the Fund.

6. Securities Loaned:

   The Fund may lend its portfolio securities in order to earn income. The Fund
will receive collateral in cash or high quality securities at least equal to
the current value of the loaned securities. The Fund earns interest on the
securities it lends and income when it invests the collateral for the loaned
securities. As of December 31, 2003, there were no securities on loan.

7. Transactions With Affiliates and Certain Other Parties:

   The Fund has entered into an Investment Advisory Agreement with Western
Asset Management Company ("Investment Adviser"), which provides for payment of
a monthly fee computed at the annual rate of 0.40% of the Fund's average weekly
assets. "Average weekly assets" means the average weekly value of the total
assets of the Fund (including any assets attributable to leverage) minus
accrued liabilities (other than liabilities representing leverage). For
purposes of calculating "average weekly assets," neither the liquidation
preference of any preferred shares outstanding nor any liabilities associated
with any instrument or transactions used by the Investment Adviser to leverage
the Fund's portfolio (whether or not such instruments or transactions are
"covered" as described in the prospectus) is considered a liability.

                                      18




   Claymore Securities, Inc. ("Servicing Agent") will act as servicing agent
for the Fund. For its services the Servicing Agent will receive an annual fee
from the Fund, payable monthly in arrears, which will be based on the Fund's
average weekly assets in a maximum amount equal to 0.15% of the Fund's average
weekly assets.

   Under the administrative agreement with the Fund, Legg Mason Fund Adviser,
Inc. ("Administrator"), an affiliate of Western Asset, provides certain
administrative and accounting functions for the Fund. In consideration for
these services, the Fund will pay the Administrator a fee, paid monthly, at an
annual rate of $100.

8. Trustee Compensation (dollar amounts are not in thousands):

   Each Trustee currently receives a fee of $8,000 annually for serving as a
Trustee of the Fund and a fee of $1,000 and related expenses for each meeting
of the Board of Trustees attended. The Chairman of the Board receives an
additional $1,500 per year for serving in that capacity. Audit Committee
members receive $500 for each meeting, and the Audit Committee Chairman
receives an additional $1,500 annually. Other committee members receive $500
per meeting.

Annual Report to Shareholders

REPORT OF INDEPENDENT AUDITORS

To the Shareholders and Trustees of Western Asset/Claymore U.S. Treasury
Inflation Protected Securities Fund:

 In our opinion, the accompanying statement of assets and liabilities,
including the portfolio of investments, and the related statements of
operations, of changes in net assets, of cash flows and the financial
highlights present fairly, in all material respects, the financial position of
the Western Asset/Claymore U.S. Treasury Inflation Protected Securities Fund
(hereafter referred to as the "Fund") at December 31, 2003, and the results of
its operations, the changes in its net assets and its cash flows, and the
financial highlights for the period presented, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these financial statements in accordance
with auditing standards generally accepted in the United States of America,
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audit, which included
confirmation of securities at December 31, 2003 by correspondence with the
custodian and brokers, provides a reasonable basis for our opinion.
