PRESIDENT'S LETTER

LM Institutional Fund Advisors I, Inc.


April 30, 1999

Dear Shareholder:

We are pleased to provide you with the financial statements for the LM
Institutional Fund Advisors I, Inc. Portfolios for the periods ended March 31,
1999. Attached are brief narratives from the portfolio managers of the Western
Asset Core, Core Plus, Intermediate, Limited Duration and Non-U.S. Fixed
Income Portfolios detailing key developments as they pertain to your
investment.

During 1998 and into 1999, the focus on the Year 2000 issue has increased
significantly. As you may know, the Year 2000 issue is a computer programming
problem that affects the ability of computers to correctly process dates of
January 1, 2000, and beyond. The Portfolios' Year 2000 project is well
underway, and is designed to ensure that the Year 2000 date change will have
no adverse impact on our ability to service our shareholders. The Portfolios
are committed to taking those steps necessary to protect Portfolio investors
including efforts to determine that the Year 2000 problem will not affect such
vital service functions as shareholder transaction processing and
recordkeeping. In addition, we are continuously monitoring the Year 2000
efforts of our vendors, and will perform tests with our critical vendors
throughout 1999. Although the Portfolios are taking steps to ensure that all
of their systems will function properly before, during, and after the Year
2000, the Portfolios could be adversely affected by computer related problems
associated with the Year 2000. Contingency plans are in place to ensure that
functions critical to the Portfolios' operations will continue without
interruption. We are on target to complete this important project and look
forward to continuing extensive testing (including industry-wide testing) with
our industry peers, regulators and vendors throughout 1999.

If you have any questions, please do not hesitate to contact us at 1-888-425-
6432. We look forward to hearing from you.

Sincerely,

Joseph L. Orlando
President
LM Institutional Advisors, Inc.

PERFORMANCE INFORMATION

LM Institutional Fund Advisors I, Inc.
Western Asset Core Portfolio

Portfolio Manager: Western Asset Management Investment Strategy Group

The impact of market conditions on the Portfolio's performance was mixed in
the twelve months ended March 31, 1999, as Treasury yields generally declined
but yields on non-Treasury issues generally rose over the course of the
period. The Portfolio's total return trailed that of its benchmark, the
Salomon Brothers Broad Market Index (SBBI), returning 5.61% (net of expenses)
vs. 6.50%, as major strategies produced mixed but generally negative results.
The Portfolio benefited from a longer than market duration posture, which it
held throughout the period, and yield curve strategies generally anticipated
the periods when short- and long-term interest rates moved by greater and
lesser degrees relative to each other. However, an overweighting to the
corporate and mortgage sectors proved to be a major drag on performance since
spreads widened significantly in the wake of the Russian liquidity crisis in
late summer. A moderate exposure to inflation-indexed bonds also detracted
from performance as real yields rose.

Western Asset Core Plus Portfolio

Portfolio Manager: Western Asset Management Investment Strategy Group

The impact of market conditions on the Portfolio's performance was mixed in
the almost nine month period from its inception through March 31, 1999, as
Treasury yields generally declined but yields on non-Treasury issues generally
rose over the course of the period. The Portfolio's total return trailed that
of its benchmark, the Salomon Brothers Broad Market Index (SBBI), returning
2.58% (net of expenses) vs. 4.09%, as major strategies produced mixed but
generally negative results. The Portfolio benefited from a longer than market
duration posture which it held throughout the period, and yield curve
strategies benefited from a decline in short rates relative to long rates.
Non-dollar bond exposure added to performance, since non-dollar bonds
generally outperformed their domestic counterparts. However, these positive
factors were more than offset by an overweighting to the corporate and
mortgage sectors, which proved to be the major drag on performance since
spreads widened significantly in the wake of the Russian liquidity crisis in
late summer. Moderate exposure to emerging market debt also proved to be a net
drag on performance since spreads ended the period substantially wider. A
moderate exposure to inflation-indexed bonds also detracted from performance
as real yields rose.

Western Asset Non-U.S. Fixed Income Portfolio

Portfolio Manager: Western Asset Management Investment Strategy Group

The Portfolio's performance was favorably impacted by market conditions in the
almost nine month period from its inception through March 31, 1999, as non-
dollar interest rates generally declined during the period. However, the
Portfolio's total return trailed that of its non-dollar benchmark, the Salomon
Brothers World Government ex-U.S. Index (Hedged), returning 5.81% (net of
expenses) vs. 6.78%/1/ , and it somewhat underperformed the broad investment
grade market (as represented by the Salomon Brothers Broad Market Index),
which returned 6.50%. The Portfolio's performance was positively impacted by
its overweight exposure to UK bonds for most of the period, as these
registered the strongest performance among bonds of industrialized countries.
These gains were more than offset, however, by the Portfolio's overweight
exposure to dollar-bloc bonds, which underperformed their European
counterparts, and more particularly by an overweight and mostly unhedged
exposure to South African bonds, as these suffered from both a depreciation of
the currency and a sharp rise in yields.

NOTES TO FINANCIAL STATEMENTS

LM Institutional Fund Advisors I, Inc.

(Amounts in Thousands)

1. SIGNIFICANT ACCOUNTING POLICIES:
LM Institutional Fund Advisors I, Inc. ("Corporation"), consisting of the
Western Asset Core Portfolio ("Core"), the Western Asset Core Plus Portfolio
("Core Plus"), the Western Asset Intermediate Portfolio ("Intermediate"), the
Western Asset Limited Duration Portfolio ("Limited") and the Western Asset
Non-U.S. Fixed Income Portfolio ("Non-U.S.") (each a "Fund"), is registered
under the Investment Company Act of 1940, as amended, as a diversified, open-
end management investment company with the exception of Non-U.S., which is
non-diversified. The Corporation was organized on May 16, 1990 and had no
operations prior to September 4, 1990, other than those related to
organizational matters. Prior to May 29, 1998, the Corporation was known as
Western Asset Trust, Inc.

Each Fund offers two classes of shares: Institutional Class and Financial
Intermediary Class. Shares in the Financial Intermediary Class bear a
distribution fee. The Financial Intermediary Class of Intermediate commenced
operations on January 7, 1999.

SECURITY VALUATION
Securities owned by the Funds for which market quotations are readily
available are valued at current market value. In determining fair value, the
Board and management consider all relevant qualitative and quantitative
information available. These factors are subject to change over time and are
reviewed periodically. The values assigned to fair value 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, those estimated values may differ significantly from
the values that would have been used had a ready market of the investments
existed, and the differences could be material. At March 31, 1999, $235 or
0.9% of Limited's net assets, were valued by management in accordance with the
procedures adopted by the Board of Directors. Securities with remaining
maturities of 60 days or less are valued at amortized cost by each Fund.

FOREIGN CURRENCY TRANSACTIONS
The books and records of the Funds are maintained in U.S. dollars. Foreign
currency amounts are translated into U.S. dollars on the following basis:

(i) market value of investment securities, assets and liabilities at the
    closing daily rate of exchange, and
(ii) purchases and sales of investment securities, interest income and
     expenses at the rate of exchange prevailing on the respective date of
     such transactions.

The effect of changes in foreign exchange rates on unrealized security gains
or losses is reflected as a component of such unrealized gains or losses. The
effect of changes in foreign exchange rates on realized security gains or
losses is reflected separately.

OPTIONS AND FUTURES
The current market value of a traded option is the last sale price or, in the
absence of a sale, the mean between the closing bid and asked price. Futures
contracts are marked-to-market on a daily basis. As a contract's value
fluctuates, payments known as variation margin are made to or received from
the futures commission merchant.

DISTRIBUTIONS TO SHAREHOLDERS
Net investment income for dividend purposes is recorded on the accrual basis
and consists of interest and dividend income less expenses. Bond premium and
original issue discount 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. Distributions are determined in accordance
with income tax regulations which may differ from generally accepted
accounting principles; accordingly, periodic reclassifications are made within
each Fund's capital accounts to reflect income and gains available for
distribution under tax regulations.

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. At March 31, 1999,
receivables for securities sold and payables for securities purchased for each
Fund were as follows:

</TABLE>

USE OF ESTIMATES
The preparation of the financial statements in accordance with generally
accepted accounting principles 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.

FEDERAL INCOME TAXES
No provision for federal income or excise taxes is required since the Funds
intend to qualify, or to continue to qualify, as regulated investment
companies and distribute all of their taxable income to their shareholders.

2. FINANCIAL INSTRUMENTS:

REPURCHASE AGREEMENTS
As part of their investment program, the Funds utilize repurchase agreements.
All repurchase agreements are fully collateralized by obligations issued by
the U.S. Government or its agencies and such collateral is in the possession
of the Funds' custodian. Risks arise from the possible delay in recovery or
potential loss of rights in the collateral should the issuer of the repurchase
agreement fail financially. The Funds' investment adviser, acting under the
supervision of the Board of Directors, reviews the value of the collateral and
the creditworthiness of those banks and dealers with which the Funds enter
into repurchase agreements to evaluate potential risks.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS
Core Plus and Non-U.S. may enter into forward foreign currency exchange
contracts to help manage their currency exposure. These contracts are marked-
to-market daily using foreign currency exchange rates supplied by an
independent pricing service. The change in a contract's market value is
recorded by a fund as an unrealized gain or loss. When the contract is closed
or delivery is taken, the fund records a realized gain or loss equal to the
difference between the value of the contract at the time it was opened and the
value at the time it was closed.

The use of forward foreign currency exchange contracts does not eliminate
fluctuations in the underlying prices of the Funds' securities, but it does
establish a rate of exchange that can be achieved in the future. These
contracts involve market risk in excess of amounts reflected in the Financial
Statements. Although contracts used for hedging purposes limit the risk of
loss due to a decline in the value of the hedged currency, they also limit any
potential gain that might result should the value of the currency increase. In
addition, the Funds could be exposed to risks if the counterparties to the
contracts are unable to meet the terms of their contracts. Each Fund's adviser
will enter into forward foreign currency exchange contracts only with parties
approved by the Board of Directors because there is a risk of loss to the
Funds if the counterparties do not complete the transaction.

Forward foreign currency exchange contracts are valued using the forward rate.
Outstanding contracts at March 31, 1999 were as follows:

OPTION 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 a
fund may forgo the opportunity of profit if the market price of the underlying
security increases and the option is exercised. The risk in writing a put
option is that a 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 a
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. Call and put options written by each Fund
and related premiums received during the period were as follows:

FUTURES
Upon entering into a futures contract, the Funds are 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 each Fund each day, depending on
the daily fluctuation in the value of the contract. For Non-U.S., payment is
not sent daily, but is recorded as a net payable or receivable by the Fund to
or from the futures broker, which is holding cash collateral from the Fund.
The daily changes in contract value are recorded as unrealized gains or losses
and each Fund recognizes a realized gain or loss when the contract is closed.
Futures contracts are valued daily at the settlement price established by the
board of trade or exchange on which they are traded.

Each Fund may enter into futures contracts in connection with its interest
rate management strategy. 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. The open long and
short futures positions and related appreciation or depreciation at March 31,
1999 are described at the end of the "Statement of Net Assets" of each Fund.

* Commencement of Operations

5. SECURITIES LOANED:
Each Fund lends its securities to approved brokers to earn additional income
and receives cash and U.S. government securities as collateral against the
loans. Cash collateral received is invested in a money market pooled account
by each Fund's lending agent. Collateral is maintained over the life of the
loan in an amount not less than 100% of the value of loaned securities. This
cash collateral is recorded as an asset with a corresponding liability.

At March 31, 1999, the market value of the securities on loan to broker-
dealers was $61,499 and $71,438 for Core and Intermediate, respectively. Cash
collateral received was $64,446 and $73,779 for Core and Intermediate,
respectively. Such

collateral is in the possession of each Fund's custodian. As with other
extensions of credit, each Fund may bear the risk of delay in recovery or even
loss of rights to the collateral should the borrower of the securities fail
financially.

6. TRANSACTIONS WITH AFFILIATES:
Each Fund has a management agreement with LM Institutional Advisors, Inc.
("LMIA"). Western Asset Management Company ("Western Asset") is the investment
adviser to Core, Core Plus, Intermediate and Limited. Western Asset Global
Management Limited ("WAGM") is the investment adviser to Non-U.S. and shares
advisory responsibilities with Western Asset for Core Plus. Pursuant to their
respective agreements, LMIA provides the Funds with management and
administrative services for which each Fund pays a fee, computed daily and
payable monthly, at annual rates of each Fund's average daily net assets as
follows: 0.45% for Core, Core Plus and Non-U.S., 0.40% for Intermediate and
0.35% for Limited. LMIA pays Western Asset a fee, computed daily and payable
monthly, at an annual rate of 0.40% of average daily net assets for Core and
Core Plus, 0.35% of average daily net assets for Intermediate and 0.30% of
average daily net assets for Limited. LMIA pays WAGM a fee, computed daily and
payable monthly, at an annual rate of 0.40% of average daily net assets for
Non-U.S. At March 31, 1999, $263, $30, $102, and $8 was due to LMIA for Core,
Core Plus, Intermediate and Non-U.S., respectively.

LMIA, Western Asset and WAGM have voluntarily agreed to waive their fees and
reimburse the Funds to the extent each Fund's expenses (exclusive of taxes,
interest, brokerage and extraordinary expenses) exceed during any month annual
rates of each Fund's average daily net assets as follows: 0.55% for Non-U.S.,
0.50% for Core, 0.50% for Core Plus, 0.45% for Intermediate and 0.40% for
Limited. At March 31, 1999, no payments were due from LMIA as reimbursement
for expenses paid above the Funds' annual expense limits.

Legg Mason Wood Walker, Incorporated ("LMWW"), a member of the New York Stock
Exchange, and Arroyo Seco, Inc. serve as distributors of the Funds. LMWW
receives from each Fund an annual distribution fee of 0.25% of the average
daily net assets of the Financial Intermediary Class of each Fund, computed
daily and payable monthly. At March 31, 1999, $1 was due to LMWW from
Intermediate. Arroyo Seco, Inc. receives no payments from the Funds in
connection with the offer or sale of their shares.

On April 8, 1999, Western Asset purchased securities valued at $235 from
Limited.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors of LM Institutional Fund Advisors I, Inc. and the
Shareholders of Western Asset Core Portfolio, Western Asset Core Plus
Portfolio, Western Asset Intermediate Portfolio, Western Asset Limited
Duration Portfolio, and Western Asset Non-U.S. Fixed Income Portfolio:

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Western Asset Core Portfolio, Western Asset Core Plus Portfolio, Western Asset
Intermediate Portfolio, Western Asset Limited Duration Portfolio, and Western
Asset Non-U.S. Fixed Income Portfolio (hereafter referred to as the "Funds")
at March 31, 1999, and the results of each of their operations, the changes in
each of their net assets and the financial highlights for each of the fiscal
periods presented, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Funds'
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards 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 audits, which included
confirmation of securities at March 31, 1999 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above.
