Dear Shareholders:

There is no doubt about it...it was a miserable quarter and a difficult nine
months. Unless you were fully invested in Treasuries, your portfolio is probably
looking rather unhealthy. However, there is hope on the horizon and, although,
perhaps it is my age, I feel very comfortable with the general outlook of the
market right now.

To use a forest fire analogy, the spark which ignited the global turmoil was
Russia. The fuel for the fire was the enormous amount of leverage which existed
in the global bond markets. Following the announcement last August that Russia
would default on some of their short-term debt, bond prices (other than
Governments) declined. The spread in the yield between U.S. Treasuries and
corporate bonds widened tremendously. The corporate bond market became
relatively illiquid and the spread between bid and ask prices widened by a
factor of 10 or more.

As one might expect, investors fled into Government bonds. Anything with the
slightest hint of risk -- even blue chip, high quality bonds -- were shunned and
their performance lagged that of Treasuries.

It is little wonder that some hedge funds ran into trouble. It is not that the
credits went bad. It was simply that two things happened at once. The Treasuries
they shorted went up, and the positions they owned went down (the same thing
happened to dealers, further reducing the liquidity of the corporate bond
market).

Fortunately, we believe things are not as bad as they seem. For us, it is
strictly a case of "same bonds, new prices", without anything going terribly
wrong with our specific holdings, but rather global market conditions. The
question remains, how many more sparks are there out there? My guess is that
sparks will continue to fly, but the major inferno is behind us.

For example, Thailand has taken serious steps to fix their banks. Korea's
current account is strong and its foreign exchange reserves have skyrocketed.
We have seen some encouraging signs in Japan.

Luckily, the Federal Reserve appears inclined to act quickly and decisively to
avoid a recession. The two rate cuts which followed each other in quick
succession (and I predict there will be more on the way) demonstrate just how
quickly things can change. Instead of trying to pull liquidity out of the
system, the Reserve Bank is trying to put liquidity into the system.

Forests don't regrow overnight and what is required now is patience. Although
it may hurt over the short run, we believe that these periods of volatility
present opportunities to buy the securities of good companies at lower prices
and higher yields. We believe that buying the securities of good companies at
low prices is the foundation of future performance.

Sincerely,

/s/ Daniel J. Fuss

LOOMIS SAYLES CALIFORNIA
TAX-FREE INCOME FUND
- -------------------------------------------------------------------------------

The Loomis Sayles California Tax-Free Income Fund attempts to achieve a high
level of current income exempt from both federal income tax and California
personal income tax as consistent with preservation of capital. For the nine
months ended September 30, 1998, the Fund had a total return of 5.30%, as
compared to the Fund's benchmark, the Lehman Brothers 5 Year Municipal Bond
Index, total return of 4.98%. For the same period, the average California
intermediate municipal debt fund, as measured by Lipper Analytical Services, had
a total return of 5.29%.

As 1998 unfolded, the more attractive relative values in California municipal
securities were those with higher coupons maturing in fifteen to twenty years
but callable in five to seven years.

During the first half of the year the Fund continued to consolidate. The Fund
also extended its call dates of new purchases from 2001-02 to 2003-05. We
believe that this extension should help maintain a high current yield plus
provide some appreciation potential as rates move lower.

Earlier in the year, underperformance was the result of a much greater than
expected supply of tax-exempt securities. More recently, the demand side for
Treasuries has exploded, as investors sought refuge in the U.S. Government
market. While more traditional buyers of tax-exempt securities, such as life
insurance companies and pension funds, have been actively accumulating municipal
securities, it is important to remember that this sector has become very rich
versus corporate bonds, especially in August. Many total return investors,
including Loomis Sayles, have taken advantage of this trend, by swapping into
the latter sector. However, we feel, for individuals in the maximum tax bracket,
municipal securities appear to be an excellent choice going forward.

The fourth quarter California municipal securities calendar should afford us the
opportunity for modest extension at attractive yield levels in the ten to
fifteen year area.

Robert K. Payne is the portfolio manager for the Loomis Sayles California Tax-
Free Income Fund.

      comparative performance purposes. This Index better represents the
      investment strategy of the Fund. The Lehman Brothers 5 Year Municipal Bond
      Index is computed from prices on approximately 6,100 bonds, with a

LOOMIS SAYLES CORE FIXED INCOME FUND
- ------------------------------------------------------------------------------

The Loomis Sayles Core Fixed Income Fund attempts to achieve high total
investment return through a combination of current income and capital
appreciation. For the nine months ended September 30, 1998, the Fund had a total
return of 7.79% as compared to the Fund's benchmark, the Merrill Lynch
Corporate/Government Bond Index, total return of 9.28%. For the same period, the
average A rated corporate debt fund, as measured by Lipper Analytical Services
had a total return of 7.47%

While returns on broad market indices were generally strong for the nine months
ended September 30, 1998, there were several factors that caused significant
differences in returns between major sectors of the market. The U.S. Treasury
Index, for example, outperformed the overall investment grade corporate bond
index by nearly 2.50%. This rather sharp repricing of the corporate bond market
was triggered by Russia's late August currency devaluation and defacto default
on its debt. Investors shunned risk in favor of the safety and liquidity of U.S.
Treasuries. Further strain was put on the market as forced liquidations of
highly leveraged trading strategies created a surge in supply of the types of
securities investors seemed to be avoiding. The combined effect of this excess
supply and reduced demand put significant pressure on corporate bonds and
mortgage-backed securities while boosting the premium paid for higher quality,
more liquid investments. Being underweighted in U.S. Treasuries, while well
supported by historical evidence, caused the Fund's performance to lag some of
the broader market indices.

Looking ahead, we see the yield advantage that has been created for U.S.
corporate bonds and mortgage-backed securities to be as compelling as it has
been since the early 1990s. In certain cases, valuations assigned to investment
grade issuers have approached recessionary levels in spite of the continued
resilience of the domestic economy. Further, with controlled inflation providing
the basis for bond market stability, the Federal Reserve has initiated a series
of interest rate cuts intended to preempt slower economic growth. Any impact
tighter credit conditions may have had on economic growth should be mitigated by
these rate cuts and any additional cuts planned before the end of 1998. Given
the strength of corporate balance sheets and the timely action by the Federal
Reserve, we believe a unique opportunity may have emerged to selectively add to
high quality corporate bond holdings at extremely attractive valuations. As
such, the Fund will continue to pursue investment grade corporate bonds armed
with the strength of Loomis Sayles' proprietary credit research.

William F. Camp is the portfolio manager for the Loomis Sayles Core Fixed
Income Fund.

LOOMIS SAYLES CORE GROWTH FUND
- --------------------------------------------------------------------------------

The Loomis Sayles Core Growth Fund attempts to achieve long-term growth of
capital. For the nine months ended September 30, 1998, the Fund had a total
return of 10.85%, as compared to the Fund's benchmark, the S&P 500 Index total
return of 6.00%. For the same period, the average growth fund, as measured by
Lipper Analytical Services, had a total return of -0.21%.

In the second quarter the shortfall in the Fund's performance versus the S&P 500
is essentially accounted for by one stock, Analog Devices. The issue declined
37% in May after reporting second quarter results 12% above the prior year but
10% below consensus expectations. Other weaknesses were in the energy sector and
some consumer nondurable stocks. Average capitalization size, while much larger
than it historically has been, also hurt, especially in the late June rally
which was almost entirely concentrated in large growth names. On the plus side,
a number of issues including Cisco, Chrysler, American Express, Warner Lambert
and EMC delivered strong performance.

The third quarter began with a continuation of the strong momentum that the June
quarter ended on. By July 20\t/\h/ the S&P 500 Index reached an all time peak of
1190.58. This was not only high in absolute terms, but, at over 26 times
prevailing estimates for 1998 earnings, was probing record territory relative to
expected earnings. At this point renewed concerns about Asia and the potential
for a spillover to other parts of the developing world, Latin America and Russia
in particular, began to impact financial markets.

A lack of exposure to some of the giant S&P 500 stocks such as General Electric
and Coca Cola which finally saw their lofty valuations contract, was one
contributor to the third quarter's good performance. Also helpful was a below
market exposure to the financial sector and an above market position in the
telephone companies. The best performing stocks included EMC, Anadarko
Petroleum, which had a potentially major discovery, Safeway, Schering-Plough,
CVS and Bell South. The worst performances were turned in by Xerox, which has a
large Brazilian operation, American International Group, which is exposed to
Asia, Circuit City, and Analog Devices.

LOOMIS SAYLES FIXED INCOME FUND
- ------------------------------------------------------------------------------

The Loomis Sayles Fixed Income Fund attempts to achieve high total investment
return through a combination of current income and capital appreciation. For the
nine months ended September 30, 1998, the Fund had a total return of -0.44%, as
compared to the Fund's benchmark, the Lehman Brothers Government/ Corporate Bond
Index, total return of 9.33%. For the same period, the average BBB rated debt
fund, as measured by Lipper Analytical Services, had a total return of 5.45%.

In the past nine months, the landscape of fixed income markets has changed
substantially. Global economic turmoil heightened investor uncertainty and led
to dramatic spread widening among corporate bonds. The Fund's Treasury holdings
were among the strongest performers benefiting from the ongoing global flight to
quality that began with the "Asian Contagion" and gained momentum with Russia
announcing its inability to meet short-term debt obligations. Further
complicating matters was Japan's inability to establish a credible plan to
restore economic order and the subsequent relatively illiquid nature of high
yield markets. The combination of these factors resulted in wider spreads in
virtually all non-Treasury market segments. The Fund's lower rated issues and
Yankee bonds were especially hard hit. Cyclical and Industrial positions
performed well for most of the period, but retreated recently as investors sold
out of bonds perceived to be leveraged to the waning economic cycle.

The Fund's significant position in Canadian government and provincial issues had
a mildly positive impact on performance, despite being hampered by a weaker
Canadian dollar. The Fund's commitment to the telecommunications and cable/media
sectors proved beneficial as telecommunications providers continue to upgrade
their network infrastructures to better accommodate both voice and data internet
traffic.

The Fixed Income Fund remains well diversified across individual issues and
countries. The Fund continues to stress call protection, yield advantage, and a
moderate degree of international exposure as a means of maximizing total return.
As a result of the recent market turbulence, we believe the Fund has built in a
meaningful yield advantage relative to the benchmark while maintaining a stable
credit profile leaving the Fund well positioned going forward.

Daniel J. Fuss is the portfolio manager for the Loomis Sayles Fixed Income Fund.

LOOMIS SAYLES HIGH YIELD FIXED INCOME FUND
- ------------------------------------------------------------------------------

The Loomis Sayles High Yield Fixed Income Fund attempts to achieve high total
investment return through a combination of current income and capital
appreciation. For the nine months ended September 30, 1998, the Fund had a total
return of -15.51%, as compared to the Fund's benchmark, the Merrill Lynch High
Yield Master Index, total return of 0.77%. For the same period, the average high
yield fund, as measured by Lipper Analytical Services, had a total return of
- -2.98%.

1998 has been a very challenging year for high yield investors. The lingering
economic crisis in Asia and the inability of Russia to meet its short-term debt
obligations triggered a capital flight from high yield bonds that forced hedge
fund managers to unwind their leveraged positions to meet margin calls. What
resulted was a relatively illiquid high yield market and the widest spreads
since the recessionary period of the early 1990s.

In terms of sector allocation, being heavily weighted in convertible bonds had a
negative impact on performance as equity markets retreated to twelve month lows.
The liquidity crisis particularly affected our Yankee exposure, as foreign bond
yields rose to their highest levels since the Mexican peso crisis in late 1994.
We continued to accumulate positions in this sector, however, throughout the
period and we remain optimistic that the easing initiative that the Fed has
embarked upon will help alleviate the credit crunch that has impeded both
emerging market and domestic high yield issuers from raising capital. Despite
underperforming in 1998, we continue to favor the Telecommunications sector
based upon the positive synergies we feel will be created for consumers by
consolidating wireless, local and long distance, cable and internet services.

As of September 30, 1998, the Fund was well diversified across 122 issues, with
a concentration in Yankee and Industrial sectors. The Fund currently holds
securities with an average dollar price of less than $60, reflecting the
embedded potential for capital appreciation as well as a commitment to call
protection. Over time, we believe the Fund's incremental yield advantage and
international diversification will provide attractive investment returns for
investors.

Income Fund.

LOOMIS SAYLES INTERMEDIATE DURATION  FIXED INCOME FUND
- -------------------------------------------------------------------------------

The Loomis Sayles Intermediate Duration Fixed Income Fund attempts to achieve
high total investment return through a combination of current income and capital
appreciation while limiting volatility through maturity limitations. For the
period since modified inception, January 31, 1998 to September 30, 1998, the
Fund had a total return of 1.50%, as compared to the Fund's benchmark, the
Lehman Brothers Government/Corporate Intermediate Bond Index, total return of
6.72%. For the same period, the average intermediate investment grade debt fund,
as measured by Lipper Analytical Services, had a total return of 6.02%.

Like other corporate bond funds, the Loomis Sayles Intermediate Duration Fixed
Income Fund was negatively impacted by the dramatic spread widening on virtually
all non-Treasury segments of the bond market that occurred over the last nine
months with most of the widening taking place in August. This repricing of risk
or "flight to quality" was the dominant factor in the performance of the Fund.
Relative to its benchmark, the Fund was underweight in Treasuries, which were
among the best performers for the period. The Fund's holdings of mortgage-backed
securities also under performed as rates declined and prepayments increased. The
Fund's Yankee bond positions were also hit during the past quarter as these
bonds became relatively illiquid. The Fund's positions in U.S. Treasury and
Canadian government bonds were strong performers.

We continue to be very comfortable with the portfolio position. The Fund is well
diversified, offers good yield advantage, and call protection. In our opinion,
the spread widening has created an appropriate time to expand positions into
corporate and Yankee bonds as the yield advantage is now significant.
Simultaneously, we are doubling our efforts on credit specific research to
ensure we are getting paid for the credit risk we take.

Anthony J. Wilkins is the portfolio manager for the Loomis Sayles Intermediate
Duration Fixed Income Fund.

LOOMIS SAYLES INVESTMENT GRADE FIXED INCOME FUND
- --------------------------------------------------------------------------------

The Loomis Sayles Investment Grade Fixed Income Fund attempts to achieve high
total investment return through a combination of current income and capital
appreciation. For the nine months ended September 30, 1998, the Fund had a total
return of -0.03%, as compared to the Fund's benchmark, the Lehman Brothers
Government/Corporate Bond Index, total return of 9.33%. For the same period, the
average BBB rated debt fund, as measured by Lipper Analytical Services, had a
total return of 5.45%.

For the nine month period, the Fund was negatively impacted by the dramatic
spread widening on virtually all non-Treasury segments of the bond markets. In
the face of the world economic crisis, losses by leveraged investors (including
hedge funds and broker dealers) and the relative illiquidity of the world
markets, investors dramatically repriced risk. Treasury bonds were bought and
most other bonds were sold. During this "flight to quality", corporate bonds,
Yankee bonds and lower quality debt all underperformed Treasuries and the Fund's
benchmark. The Investment Grade Fixed Income Fund, by its style, held large
positions in corporate bonds and modest positions in Yankees and non-dollar
bonds. As a result, the Fund was largely underweight in Treasury bonds. This
difference in focus was the major factor in determining relative performance
results for the period. The U.S. Treasury positions and Canadian government
bonds did perform well, however.

As of September 30, 1998, the Fund maintained its focus on corporate bonds with
modest exposure to foreign issuers, including Yankee bonds and non-dollar
positions primarily in Canada. We have not changed our portfolio positions
dramatically, and we have not overreacted to the market conditions. Rather, we
view this as an appropriate time to expand positions in these areas as the yield
advantage has risen. At the same time, we are as diligent as ever on credit
risk. We believe that the Fund's holdings are well diversified.

In summary, we believe the Fund exhibits very strong yield advantage, call
protection and non-market-related factors. Overall, we are very comfortable with
the Fund's position vis-a-vis current world and capital market conditions. For
the long-term investor, we believe there is value in the current structure.

Daniel J. Fuss is the portfolio manager for the Loomis Sayles Investment Grade
Fixed Income Fund.

LOOMIS SAYLES INVESTMENT TRUST
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
September 30, 1998

1.  Loomis Sayles Investment Trust (the "Trust") consists of seven no-load
mutual funds (the "Funds").

The Trust was organized as a Massachusetts business trust under the laws of
the Commonwealth of Massachusetts on December 23, 1993. The Trust is a
diversified, open-end management investment company registered with the
Securities and Exchange Commission under the Investment Company Act of 1940,
as amended (the "1940 Act"), and the interests in which were registered for
offer and sale, effective March 7, 1997, under the Securities Act of 1933, as
amended (the "1933 Act"). The Trust is authorized to issue an unlimited number
of full and fractional shares of beneficial interest in multiple series.

Each Fund is separately managed and has its own investment objective and
policies. Loomis, Sayles & Company, L.P. ("Loomis Sayles") is the investment
adviser of each fund.

The Trust consists of the following Funds:

      Loomis Sayles California Tax-Free Income Fund
      Loomis Sayles Core Fixed Income Fund
      Loomis Sayles Core Growth Fund
      Loomis Sayles Fixed Income Fund
      Loomis Sayles High Yield Fixed Income Fund
      Loomis Sayles Intermediate Duration Fixed Income Fund
      Loomis Sayles Investment Grade Fixed Income Fund

The preparation of 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 those estimates. Effective September 30,
1998, the Board of Trustees approved a change in the fiscal year end of the
Funds to September 30, 1998. Certain amounts in the Statements of Operations
and Statements of Changes in Net Assets for prior periods have been
reclassified to conform to current period presentations. The following
summarizes the significant accounting policies of the Loomis Sayles Investment
Trust Funds:

A.  SECURITY VALUATION --  Long-term debt securities for which quotations are
readily available are valued by a pricing service, as approved by the Board of
Trustees, which generally uses the most recent bid prices in the principal
market in which such securities are normally traded. Municipal debt securities
are valued by a pricing service, as approved by the Board of Trustees, which
generally uses a computerized matrix system or dealer supplied quotations that
consider market transactions for comparable securities. Equity securities for
which quotations are readily available are valued at their last sale price on
the exchange where primarily traded or, if there is no reported sale during
the day, at the closing bid price. Short-term securities with a remaining
maturity of 60 days or less are valued at amortized cost, which approximates
market value. Other securities for which quotations are not readily available
(including restricted securities, if any) are valued primarily using dealer
supplied quotations or at their fair values as determined in good faith under
the general supervision of the Board of Trustees

B.  REPURCHASE AGREEMENTS -- The Funds may engage in repurchase agreement
transactions. Under the terms of a typical repurchase agreement, the Funds
take possession of an underlying debt obligation subject to an obligation of
the seller to repurchase, and the Funds to resell, the obligation at an
agreed-upon price and time. This arrangement results in a fixed rate of return
that is not subject to market fluctuations during the Funds' holding period.
The Funds, through their custodian, receive delivery of the underlying
securities collateralizing repurchase agreements. It is the Funds' policy that
the market value of the collateral be at least equal to 102% of the repurchase
price. These securities are marked-to-market daily. Loomis Sayles is
responsible for determining that the value of the collateral is at all times
at least equal to 102% of the repurchase price. In connection with
transactions in repurchase agreements, if the seller defaults and the value of
the collateral declines or if the seller enters into insolvency proceedings,
realization of the collateral by the Funds may be delayed or limited.

C.  FOREIGN CURRENCY TRANSLATION AND FOREIGN INVESTMENTS -- The books and
records of each of the Funds (including those Funds that invest in foreign
securities) are maintained in U.S. dollars. The value of securities,
currencies and other assets and liabilities denominated in currencies other
than U.S. dollars is translated into U.S. dollars based upon foreign exchange
rates prevailing at the end of the period. Purchases and sales of investment
securities are translated at contractual currency exchange rates established
at the time of the trade. Income and expenses are translated at prevailing
exchange rates on the respective dates of such transactions.

The results of operations resulting from changes in foreign exchange rates on
investments are not isolated from fluctuations arising from changes in market
prices of securities held. All such fluctuations are included with net
realized and unrealized gain or loss from investments.

Net realized and unrealized gains and losses on foreign currency transactions
represent foreign exchange gains and losses from the sale of short-term
securities and holdings of foreign currencies, foreign currency gains and
losses between trade dates and settlement dates on investment securities
transactions, sales and maturities of forward foreign currency exchange
contracts, and the difference between the amounts of daily interest accruals
on the books of the Funds and the amounts actually received resulting from
changes in exchange rates on the payable date.

Certain funds use foreign currency exchange contracts to facilitate
transactions in foreign-denominated securities. Losses may arise from changes
in the value of the foreign currency or if the counterparties do not perform
under the contracts' terms. The U.S. dollar value of foreign currency is
determined using contractual currency exchange rates established at the time
of each trade. The cost of the foreign currency exchange contracts is included
in the cost basis of the associated investment.

Each Fund (except the California Tax-Free Income Fund) may purchase securities
of foreign issuers. Investing in securities of foreign companies and foreign
governments involves special risks and considerations not typically associated
with investing in U.S. companies and securities of the U.S. government. These
risks include revaluation of currencies and the risk of appropriation.
Moreover, the markets for securities of many foreign companies and foreign
governments may be less liquid, and the prices of such securities may be more
volatile than those securities of comparable U.S. companies and the U.S.
government.

D.  FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS  -- Each Fund that may invest
in foreign securities may enter into forward foreign currency exchange
contracts to protect securities against changes in future foreign exchange
rates. A forward foreign currency exchange contract is an agreement between
two parties to buy or sell currency at a set price on a future date.

The market value of the contract will fluctuate with changes in currency
exchange rates. The contract is marked-to-market daily using the forward
currency exchange rate and the change in market value is recorded as
unrealized appreciation (depreciation) on foreign currency translations in the
Funds' Statements of Assets and Liabilities. Realized gain or loss is
recognized when the contract is closed 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 and recorded as realized gain (loss) on foreign currency
transactions in the Funds' Statements of Operations.

Risks may arise upon entering into forward foreign currency exchange contracts
from the potential inability of the counterparties to meet the terms of their
contracts and from unanticipated movements in the value of a foreign currency
relative to the U.S. dollar. At September 30, 1998 there were no open forward
foreign exchange contracts.

E.  SECURITY TRANSACTIONS, RELATED INVESTMENT INCOME AND EXPENSES -- Security
transactions are accounted for on the trade date (the date the buy or sell is
executed). Dividend income is recorded on the ex-dividend date and interest
income is recorded on the accrual basis. Interest income is increased by the
accretion of discount. Discounts on zero coupon bonds, original issues, step
bonds and payment in kind bonds are accreted according to the effective
interest method. Interest income on the California Tax-Free Income Fund is
decreased by the amortization of premium. Premiums are amortized using the
yield to maturity method. In determining net gain or loss on securities sold,
the cost of securities has been determined on the identified cost basis.

Most expenses of the Trust can be directly attributed to a particular fund.
Expenses which cannot be directly attributed are apportioned among the Funds
based upon relative net assets.

F.  WHEN-ISSUED SECURITIES -- Each Fund may purchase securities on a when-
issued basis. Securities purchased on a when-issued basis are purchased for
delivery beyond the normal settlement period at a stated price and yield, and
no income accrues to the Fund on such securities prior to delivery. Each Fund
instructs the custodian to establish a segregated account in which it
maintains liquid assets at least equal to the amount of its when-issued
purchase commitments. Purchasing securities on a when-issued basis may involve
a risk that the market price at the time of delivery may be lower than the
agreed-upon purchase price, in which case there could be an unrealized loss at
the time of delivery. At September 30, 1998, the Funds had no such
commitments.

G.  FEDERAL INCOME TAXES  -- Each Fund is a separate entity for federal income
tax purposes. Each Fund intends to meet the requirements of the Internal
Revenue Code applicable to regulated investment companies, and to distribute
to its shareholders all of its net investment income and any net realized
capital gains. Accordingly, no provision for federal income tax or excise tax
has been made.

At September 30, 1998, the California Tax-Free Income and Intermediate
Duration Fixed Income Funds had available capital loss carryforwards of $2,744
and $44,716, respectively, which will expire on September 30, 2006. These
realized losses are intended to be used to offset future net capital gains.

H.  DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The California Tax-Free
Income, the Intermediate Duration Fixed Income and the Investment Grade Fixed
Income Funds pay their net investment income monthly. The Core Fixed Income,
Core Growth, Fixed Income and High Yield Fixed Income Funds pay their net
investment income to shareholders annually. Distributions from net realized
capital gains, if any, are declared and paid on an annual basis by all of the
Funds. Income and capital gain distributions are determined in accordance with
Federal income tax regulations which may differ from generally accepted
accounting principles. These differences, which may result in
reclassifications to the Fund's capital accounts to reflect income and gains
available for distribution, are primarily due to differing book and tax
treatments for foreign currency transactions, deferred losses due to wash
sales and excise tax regulations. Some of these classifications may include
temporary book and tax basis differences that will reverse in subsequent
periods.

I.  ORGANIZATION EXPENSE -- In 1996, costs approximating $11,970 were incurred
in connection with the initial registration and organization of the Core Fixed
Income Fund. These costs were paid by the Fund and are being amortized over 60
months.

2.  PURCHASES AND SALES OF SECURITIES -- (excluding short-term investments)
for each Fund for the nine months ended September 30, 1998 were as follows:

Investment Grade Fixed Income Fund ......      19,248,752            11,495,365

3.  MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES -- For the nine
months ended September 30, 1998, the Funds incurred management fees payable to
Loomis Sayles. Certain officers and directors of Loomis Sayles are also
officers or Trustees of the Trust. Loomis Sayles' general partner is
indirectly owned by NVEST, L.P., a publicly-traded limited partnership whose
general partner is indirectly owned by Metropolitan Life Insurance Company.
Separate management agreements for each Fund in effect during the nine months
ended September 30, 1998 provided for fees at the following annual percentage
rate of each Fund's average daily net assets indicated below. Loomis Sayles
voluntarily agreed, for an indefinite period, to reduce its advisory fees and/
or bear other expenses, to the extent necessary to limit the total operating
expenses of the Funds to the following percentage rate of the Fund's average
annual net assets:

                                                           Maximum Operating
                   Fund                    Management Fees   Expense Ratio
                   ----                    ---------------   -------------

California Tax-Free Income Fund ...........     0.50%            0.65%
Core Fixed Income Fund ....................     0.50%            0.65%
Core Growth Fund ..........................     0.50%            0.65%
Fixed Income Fund .........................     0.50%            0.65%
High Yield Fixed Income Fund ..............     0.60%            0.75%
Intermediate Duration Fixed Income Fund ...     0.40%            0.55%
Investment Grade Fixed Income Fund ........     0.40%            0.55%

Loomis Sayles may change or terminate these voluntary agreements at any time,
but the relevant prospectus would be supplemented at the time to describe the
change.

A.  TRUSTEES FEES AND EXPENSES -- The Trust does not pay any compensation
directly to its officers or Trustees who are directors, officers or employees
of Loomis Sayles, Metropolitan Life Insurance Company or their affiliates.
Each independent Trustee is compensated by the Trust at the rate of $10,000
per annum, plus travel expenses for each meeting attended. These expenses are
allocated evenly among the Funds in the Trust.

4.  CREDIT RISK -- The High Yield Fixed Income Fund will invest at least 65%,
the Fixed Income Fund may invest up to 35%, and the Investment Grade Fixed
Income Fund may invest up to 10% of its total net assets in securities
offering high current income, which generally will be in the lower rating
categories of recognized rating agencies. These securities are regarded as
predominantly speculative with respect to the capacity to pay interest and
repay principal in accordance with the terms of the obligations and will
generally involve more credit risk than securities in the higher-rated
categories. In addition, the trading market for high yield securities may be
relatively less liquid than the market for higher-rated securities.

5.  CONCENTRATION -- The California Tax-Free Income Fund primarily invests in
debt obligations issued by the State of California, its political
subdivisions, agencies and public authorities to obtain funds for various
public purposes. The Fund is more susceptible to factors adversely affecting
issuers of California municipal securities than is a municipal bond fund that
does not concentrate its investments in the securities of issuers of a single
state.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Trustees of the Loomis Sayles Investment Trust Funds:

In our opinion, the accompanying statements of assets and liabilities,
including the portfolio of investments owned, 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 the Loomis Sayles
Investment Trust Funds (consisting of the Loomis Sayles California Tax-Free
Income Fund, Core Fixed Income Fund, Core Growth Fund,  Fixed Income Fund,
High Yield Fixed Income Fund, Intermediate Duration Fixed Income Fund, and
Investment Grade Fixed Income Fund) (collectively, the "Funds") at September
30, 1998, and the results of their operations, the changes in their net assets
and the financial highlights for the periods indicated, in conformity with
generally accepted accounting principles. 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 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 investments owned at September 30,
1998 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.
