                Dear Shareholders:

                   The bad news is that the last six months were relatively
                   fruitless for most areas of fixed income. The good news is
                   that the worst is behind us and things are looking brighter
                   on the horizon.

                   The degree of leverage in the bond market seems to be
                   increasing once again. Dealers continue to be cautious and
                   institutions that lend to hedge funds are still careful, but
                   slowly becoming more liberal than last fall. If this
                   continues, market liquidity will further improve and spreads
ought to narrow, allowing corporate yields to either fall faster or rise slower
than treasury yields. Either scenario represents favorable price movements for
corporate bonds.

Despite a floundering market, the Loomis Sayles Fixed Income Fund performed very
well in the past six months. Our motto has become "same bonds, new prices." The
investments made in undervalued bonds earlier in 1998 bore fruit in the last six
months. We had a strong fourth quarter as liquidity flowed back into the market,
helping restore a modicum of rationality on valuation spreads. These two factors
helped us produce positive performance relative to the rest of the market.

In the equity arena, growth stocks continue to be in favor over value. The
technological revolution is almost solely responsible for the market's momentum.
For the first quarter of 1999, only 172 stocks in the S&P 500 beat the
capitalization-weighted index average. These stocks represent 34% of the
equal-weighted index but 47% of the size-weighted index. On a size-weighted
basis, Standard & Poor's classifies over 20% of the outperforming stocks as
technology companies. Four of the seven largest contributors to the excess
return of the market were Microsoft, America Online, EMC Corp. and Cisco
Systems, all technology-related companies. Technology, with a return of nearly
12%, was the only industrial sector to exceed 8% for the first quarter.

There are some uncertainties for both the fixed income and equity markets. For
instance, we cannot predict the outcome of the tragic situation in the Balkans,
the effect of the Euro, the future of internet-related stocks or how soon or how
much interest rates will fluctuate. Our best course of action is precaution. As
a result of this uncertainty, we have positioned our funds so that they should
weather wider than normal market swings. The way in which we do this is to buy
as much as we can that is not directly related to the markets -- without giving
up potential performance. Looking forward,

                                       1

the funds are structured to take advantage of the above average spreads between
U.S. Treasuries and everything else that exists in the current market.

It has been an exciting six months for Loomis Sayles Investment Trust. Mutual
fund assets were $514 million at March 31. This represents a $47 million
increase over the past six months. We attribute most of this growth to the
Loomis Sayles Fixed Income and Investment Grade Fixed Income Funds. We are proud
of our accomplishments over the past six months and look forward to new
challenges and achievements for the '99 fiscal year.

Sincerely,

           [SIG]

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 six
months ended March 31, 1999, the Fund had a total return of 1.53%, as compared
to the Fund's benchmark, the Lehman Brothers 5 Year Municipal Bond Index, total
return of 1.87%. For the same period, the average California intermediate
municipal debt fund, as measured by Lipper Analytical Services, had a total
return of 1.02%.

The Fund has earned its coupon during the last two quarters which by comparison
to the action of the Treasury market is an excellent result. The government
market experienced a lot of volatility and upward yield movement throughout the
yield curve. The 5 year Treasury moved from 4.21% to 5.10%, the 10 year from
4.41% to 5.23% and the 30 year from 4.97% to 5.62%. At the same time, municipal
yields moved higher at a more modest pace, and interestingly the one to five
year California curve moved to lower yields. The 5 year benchmark California
municipal moved from 3.90% to 3.83% while the 10 year was unchanged at 4.25% and
the 30 year moved from 4.86% to a 5.06%.

During the six month period, we sold one holding that had been pre-refunded for
October 1999 at a yield under 3.00%. We used the proceeds to purchase good
quality ten to twenty year maturities with calls in seven to nine years at
yields close to 5.00%.

Going forward, we feel the Fund is well positioned with a weighted average life
of 5.13 years and weighted average duration of 4.19 years.

ROBERT K. PAYNE IS THE PORTFOLIO MANAGER FOR THE CALIFORNIA TAX-FREE INCOME
FUND.

     Securities Act of 1933 on March 7, 1997. In accordance with SEC
     regulations, performance information is provided for the period beginning
     on March 7, 1997 ("Registration"). For the convenience of our long-term
     shareholders, performance information is also provided for the period
     beginning on June 1, 1995 ("Inception"). Since Lipper California
     Intermediate Municipal Bond Fund Index & Lehman Brothers 5 Year Municipal
     Bond Index performance data is not available coincident with the
     registration date, comparative performance is presented from March 31,
     1997.

     approximately 6,100 bonds, with a maturity range of 4-6 years, consisting
     of roughly 23% revenue bonds, 24% general obligation bonds, 41% insured
     bonds, and 12% prerefunded bonds. The index returns have not been reduced
     for ongoing management and operating expenses applicable to mutual fund
     investments. Source: Lehman Brothers.

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

The Loomis Sayles Core Fixed Income Fund attempts to achieve a high total
investment return through a combination of current income and capital
appreciation. For the six months ended March 31, 1999, the Fund had a total
return of -0.34% as compared to the Fund's benchmark, the Merrill Lynch
Corporate/Government Bond Index, total return of -0.97%. For the same period,
the average A rated corporate debt fund, as measured by Lipper Analytical
Services had a total return of 0.96%

During the past six months we have seen a continuation of strong economic growth
with low inflation. The Federal Reserve lowered the Federal Funds rate three
times restoring confidence and improving liquidity within the bond market. These
factors combined to produce a solid recovery in valuation within the corporate
and mortgage sectors.

The Fund's longer-term strategic position was little changed over the last six
months. However, we moved aggressively to take advantage of opportunities
created during the liquidity crunch. We added to both our corporate and mortgage
sector allocations as extraordinary values were created in issues with strong
fundamentals. Specifically, within the corporate sector we have added to our
energy sector holdings as we find these issues undervalued relative to similarly
rated bonds for those companies with strong balance sheets and the ability to
weather low oil prices. We also reduced the Fund's average maturity/duration
slightly in anticipation of higher interest rates. All of these changes had a
positive effect on performance during the last six months.

On the positive side the securities that contributed most to the Fund's
performance were Coastal Corp., Norfolk Southern, ConAgra and Lehman Brothers.
On the negative side Meditrust, Boise Cascade and Saga Petroleum were all weak
performers.

We believe that yield will be the key factor in performance in 1999. Our outlook
is based on the continued trend of strong economic growth combined with low
inflation. This economic background should result in stable interest rates and a
focus by investors on yield. We believe the Fund is well positioned to benefit
from this outlook and our expectation is for continued outperformance in the
corporate and mortgage sectors.

WILLIAM F. CAMP IS THE PORTFOLIO MANAGER FOR THE 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 six months ended March 31, 1999, the Fund had a total return of
27.74%, as compared to the Fund's benchmark, the S&P 500 Index total return of
27.34%. For the same period, the average growth fund, as measured by Lipper
Analytical Services, had a total return of 28.16%.

The fourth quarter of 1998 began on a turbulent note as investors continued to
ponder the implications of the Russian default and the Long Term Capital
Management failure. The Federal Reserve's move on October 14th to lower interest
rates for the second time set a recovery in motion that proceeded almost without
interruption for the remainder of the year with most major indexes ending the
year at or above their July highs. For the quarter, the S&P 500 posted a 21.3%
gain while the full year recorded a 28.6% advance marking the fourth consecutive
year of better than 20% returns. As has been the case for most of this period,
1998's market was characterized by very narrow leadership. Size was critical --
the fifty largest S&P companies had a median gain of 33.6% for the year versus
5.1% for the remaining 450 names. Performance was also concentrated in
relatively few industry sectors with technology and communications services --
both of which were driven by the Internet -- being the leaders.

As the first quarter of 1999 began, investors were focused on Brazil where a
collapsing currency and capital flight were producing fears of still another
chapter in the global financial crisis that began in Thailand in August of 1997
and spread through southeast Asia, Korea, and on to Russia. World economic
recovery seemed further off than ever, and the market continued to favor the
same handful of large growth stocks that contributed so disproportionately to
1998's performance. While most managers have learned with varying degrees of
success to cope with this market phenomenon, which was driven by the unusual
combination of a strong US economy in the midst of worldwide recession and a
massive flow of funds into indexed and quasi-indexed portfolios, many of us,
particularly that minority who have experienced a bear market, have been
profoundly uneasy. Fortunately, the market started to change in March as
investors began to gather increasing amounts of anecdotal evidence that parts of
Asia were beginning to recover and that the Brazilian crisis was looking much
less serious than its predecessors. Coupled with an apparently successful OPEC
production-cutting agreement, this caused investors to begin to think of the
implications of a growing worldwide economy and rising rather than falling
commodity prices.

                                       7

The new quarter has begun with a continuation of the shift in leadership to
cyclicals and energy that began in March. Stocks in industries such as
machinery, paper, metals, and energy, which in some cases had lagged the market
for years, exploded to the upside even as former leaders in technology and
health care declined sharply. The Dow Jones Industrial Average far outperformed
the broader based S&P 500 and, particularly, the technology-laden NASDAQ.
Typically, when a shift in leadership of this magnitude occurs it is a harbinger
of market trends that are likely to remain in place for an extended interval. In
this case, we believe it is signaling the likelihood of a strengthening world
economy quite different from the recent past in which a world recession and a
strong dollar allowed the US to enjoy strong inflation free growth. In this new
environment, inflation and, eventually, interest rates will be higher,
price/earnings multiples will contract, and strong earnings growth will be
essential for good stock performance. We believe the portfolio is well
positioned for this environment, and we will endeavor to remain alert for new
opportunities.

QUENTIN P. FAULKNER IS THE PORTFOLIO MANAGER FOR THE CORE GROWTH 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
six months ended March 31, 1999, the Fund had a total return of 7.23%, as
compared to the Fund's benchmark, the Lehman Brothers Government/Corporate Bond
Index, total return of -1.07%. For the same period, the average BBB rated debt
fund, as measured by Lipper Analytical Services, had a total return of 0.44%.
Our outperformance can be attributed, in large part, to a more favorable global
economic climate, an across the board compression of credit spreads, and
fortuitous issue selection.

Three consecutive cuts in short-term interest rates by the Federal Reserve
brought an end to the "flight to quality", causing investors to swap out of
particularly rich Treasuries into other segments of the market. Yield spreads
versus Treasuries narrowed dramatically across the credit spectrum, with lower
rated bonds performing the best. In our portfolios, it was just a case of same
bonds, different prices. We did not initiate any dramatic repositioning when
liquidity dried up last fall, rather, we attempted to capitalize on the deeply
discounted nature of the market by opportunistically buying issues of
companies/countries that we believed would weather the crisis the best.

The Fund was well positioned to benefit from this transition, particularly in
the Yankee sector, where we had been accumulating positions since the "Asian
Contagion" began. Korea had their sovereign rating and several of their
corporate issuer's debt ratings upgraded by the major debt rating agencies
because of the country's success in implementing fiscal reforms and stabilizing
their currency. The Fund's energy exposure, which has been hampered by soft
demand from Asia and a prolonged weakness in oil prices, rebounded nicely in
March as a result of a more favorable outlook for the sector. This exposure also
acts as a sound hedge against inflation should it materialize. In addition, the
Fund has maintained a considerable position in Canadian government & provincial
debt due to Canada's strong credit profile and the liquidity and call-protection
these bonds provide.

We remain constructive on the market at current levels. Although yield spreads
have tightened recently, they remain wide by historical standards, particularly
in the Yankee and commodity-sensitive sectors. These sectors, along with the
Telecommunications and Cable/Media continue to be areas of focus. The Fund
remains well diversified across 226 issues and more than 20 countries, while
offering call protection and a significant yield advantage over Treasuries.

DANIEL J. FUSS IS THE PORTFOLIO MANAGER FOR THE 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 six months ended March 31, 1999, the Fund had a total
return of 14.94%, as compared to the Fund's benchmark, the Merrill Lynch High
Yield Master Index, total return of 3.98%. For the same period, the average high
current yield fund, as measured by Lipper Analytical Services, had a total
return of 5.74%.

Credit spreads have tightened considerably since the recessionary levels reached
during the global liquidity crisis last fall. Three consecutive cuts in
short-term interest rates by the Federal Reserve ended the "flight to quality"
and alleviated some of the pressure on capital starved regions in Southeast Asia
and Latin America. This had a positive impact on the Fund, which had suffered as
a result of the recent lack of liquidity in the high yield market. Our Yankee
positions firmed as capital flows began to flow freely again, which helped
stabilize currencies in Asia and Latin America and allowed them to begin to
rebuild their struggling economies. The stock market rebounded sharply off its
October lows as well, giving a boost to our significant convertible bond
exposure. The Fund's focus in the Telecommunications sector paid off, as demand
in this sector increased as a result of new technological advances, rapid
industry growth, and improving fundamentals. Commodity sensitive issues, and
energy related credits in particular, lagged as a result of the supply/demand
imbalances plaguing the oil industry. We began to see a firming of oil prices in
March however, and should inflationary pressures begin to materialize, this
exposure will provide attractive returns as well as a sound hedge against
inflation.

We remain constructive on the market at current levels. Although yield spreads
have tightened recently, they remain wide by historical standards, particularly
in the Yankee and commodity sensitive sectors. The portfolio continues to
emulate our "bond picking" style which focuses on individual credit specifics
while attempting to capitalize on secular changes in sectors/ sovereigns to
capture attractive yields and lock them in for extended periods of time.

DANIEL J. FUSS IS THE PORTFOLIO MANAGER FOR THE HIGH YIELD FIXED 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. For the six months ended March 31, 1999, the Fund had a total
return of 2.65%, as compared to the Fund's benchmark, the Lehman Brothers
Government/Corporate Intermediate Bond Index, total return of 0.10%. For the
same period, the average intermediate investment grade debt fund, as measured by
Lipper Analytical Services, had a total return of -0.45%.

The beginning of the fiscal year was marked by a massive, global "flight to
quality", triggered by recession in Asia, Russia's default, and the subsequent
de-coupling of markets that occurred as leveraged investors unwound their
positions into the market. Fortunately, the Federal Reserve Bank stepped in with
three consecutive cuts in interest rates, which provided much needed liquidity
for the market, and eventually brought an end to the panic. The yield on the 10
year Treasury fell to 4.16% at the height of the crisis in early October, but
would only test those levels for a short time, before retreating to 5.24% by
March 31, 1999. Diminished expectations of future interest rate cuts, rising
Japanese bond yields, and a stronger than expected domestic economy led
investors to swap out of particularly rich Treasuries into other segments of the
market during the first quarter.

The Fund was positioned well to benefit from this transition. Mortgage and asset
backed exposure had a positive impact on performance, outperforming similar
duration Treasuries on a relative basis. Our modest Yankee allocation provided a
boost to performance. One notable performer in this group was Korea Development
Bank, which rallied after being upgraded to investment grade status. RJR Nabisco
bonds rallied following the company's announcement that it planned to spin off
its domestic tobacco unit, and sell off its international tobacco unit, which
will allow the company to de-leverage and avoid possible future costly
litigation. In addition, our exposure to the REIT sector proved beneficial as
REIT spreads rallied in the first quarter, following a disappointing 1998.

We are comfortable with the overall structure of the Fund and will continue to
focus on undervalued bonds with call protection that offer good yield advantage.
The duration of the Fund remains longer than that of the benchmark index to
capture the higher yield offered by extending out over the corporate curve and
to enhance capital appreciation should yield spreads narrow.

ANTHONY J. WILKINS IS THE PORTFOLIO MANAGER FOR THE 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 six months ended March 31, 1999, the Fund had a total
return of 6.37%, as compared to the Fund's benchmark, the Lehman Brothers
Government/Corporate Bond Index, total return of -1.07%. For the same period,
the average BBB rated debt fund, as measured by Lipper Analytical Services, had
a total return of 0.44%.

Three consecutive cuts in short-term interest rates by the Federal Reserve
brought an end to the "flight to quality," causing investors to swap out of
particularly rich Treasuries into other segments of the market. In the
investment grade bond market, demand continued to be strong. Robust mutual fund
inflows and increased participation from the broker/dealer community provided
more than enough liquidity to support the active primary and secondary markets.
The Fund's considerable position in Canadian government and provincial debt
appreciated markedly over the last six months, as a result of Canada's improving
credit profile, the strengthening Canadian dollar, and the attractive structure
of their debt (i.e. good call protection & liquidity). Our modest Yankee
allocation provided a boost to performance as well, with bonds such as Enersis,
Korea Electric & Power, and Telekom Malaysia making strong advances. Also
noteworthy was the strong performance of the REIT sector, which added value as
spreads in this sector narrowed measurably over the first half of the fiscal
year.

We believe that the current portfolio is strongly positioned vis-a-vis global
market conditions. We remain underweight in the Treasury sector relative to the
benchmark, primarily because we believe there is better value and more
attractive yields in other segments of the market. Areas of focus continue to be
the Yankee, Energy, REIT, and Canadian government and provincial sectors. The
Fund currently exhibits an attractive yield advantage and good diversification
across sectors and countries. The Fund has a longer average maturity and
duration than that of its benchmark to capture additional yield and lock it in
through the call protection inherent in longer maturity bonds.

DANIEL J. FUSS IS THE PORTFOLIO MANAGER FOR THE INVESTMENT GRADE FIXED INCOME
FUND.

(a): Inception date of the Loomis Sayles Investment Grade Fixed Income Fund is
     July 1, 1994. Shares of the Fund were registered for offer and sale under
     the Securities Act of 1933 on March 7, 1997. In accordance with SEC
     regulations, performance information is provided for the period beginning
     on March 7, 1997 ("Registration"). For the convenience of our long-term
     shareholders, performance information is also provided for the period
     beginning on July 1, 1994 ("Inception"). Since Lipper BBB Rated Bond Fund
     Index & Lehman Brothers Government/Corporate Bond Index performance data is
     not available coincident with the registration date, comparative
     performance is presented from March 31, 1997.

LOOMIS SAYLES INVESTMENT TRUST
- ------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
MARCH 31, 1999 (UNAUDITED)
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. Certain amounts in the 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

                                       85
<PAGE>
LOOMIS SAYLES INVESTMENT TRUST
- ------------------------------------------------
NOTES TO FINANCIAL STATEMENTS continued
MARCH 31, 1999 (UNAUDITED)
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

                                       86
<PAGE>
LOOMIS SAYLES INVESTMENT TRUST

NOTES TO FINANCIAL STATEMENTS continued
MARCH 31, 1999 (UNAUDITED)
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

                                       87

contracts and from unanticipated movements in the value of a foreign currency
relative to the U.S. dollar. At March 31, 1999, there were no open forward
foreign currency 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.  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.

G.  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.

H.  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.

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 six months ended March 31, 1999
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

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.

6.  IN-KIND TRANSACTIONS -- During the six months ended March 31, 1999, the High
Yield Fixed Income Fund had realized losses of $871,366 on securities associated
with an in-kind redemption on January 26, 1999.
