LETTER FROM THE PRESIDENT

[PHOTO]

DANIEL J. FUSS
PRESIDENT AND
PORTFOLIO MANAGER

DEAR SHAREHOLDERS,

The last six months ended March 31, 2000 showed continued strength in the U.S.
stock market and changing conditions in the U.S. bond market. The broad bond
market finished 1999 on a disappointing note, with rising interest rates and
negative returns for most sectors. While short-term rates continued to climb
into 2000, the higher-quality, longer-term sectors rebounded somewhat during the
first three months of 2000, led in large part by a bounce-back in the U.S.
Treasury sector.

At Loomis Sayles, our domestic bond funds successfully persevered through the
challenging bond market climate of the past six months. Spreads remained wide
throughout the period, which presented us with excellent long-term buying
opportunities. Because our expertise is in researching and selecting attractive
bonds, we were very comfortable with this environment.

The worst may be over for the bond market, and we're probably already off the
bottom. But, because short-term rates may continue to rise for a while, barring
a stock market drop, the market shouldn't get away from us on the upside. It's a
good time to be gradually buying discount, reasonable credits with fairly long
maturities. It's also important to get extra value by emphasizing
non-market-related factors. We have to remain cautious with corporate bonds,
though, because it's a very competitive market. All in all, it's a
better-than-average time to be in the market, particularly if focused on long,
discount, non-Treasury securities.

In the equity arena, growth stocks across all capitalization ranges remained on
a strong upward course, led by the powerful, high-flying technology sector. A
couple of rallies among value stocks were short-lived, and the growth-stock
sector emerged as the unrivaled style leader for the period.

As we look ahead, the levels of debt in the economies of the major countries
remain a valid concern. As short-term interest rates move up, this may serve as
a depressant on the financial markets and a slowing mechanism for the economies.
Nevertheless, this one factor alone doesn't seem to be enough to put an end to
the economic expansion. In fact, unless the central banks go overboard, there
really is no visible factor threatening to clobber the economies.

<PAGE>


There are many factors, though, that appear to be dampeners of economic growth,
particularly in North America: relatively full employment, rising short-term
interest rates and the resulting slowing of private-sector borrowing, and some
deterioration in consumer sentiment. Put together, these factors could and
should slow the level of economic expansion to something more in line with
normal growth.

The magnitude of stock-market leverage also is an important and growing concern
in the U.S., Europe and Japan. The Federal Reserve Board has said it won't raise
margin requirements, but a market that trends sharply downwards could feed on
itself. Those investing in volatile instruments with borrowed money eventually
will have to face up to it, and this really could put a damper on the stock
market and the economy. Stock market valuations in the U.S., and to a lesser
degree in Europe, also remain a concern given the extraordinary returns in the
past five years. These are huge markets, and a return to more normalized
performance could be disappointing in the future.
If this does occur, though, I suspect it will be a gradual process.

Sincerely,

/s/ Daniel J. Fuss

FUND AND MANAGER REVIEW

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-month period ended March 31, 2000, the Fund had a total return of 1.57%, as
compared to the Fund's benchmark, the Lehman Brothers 5 Year Municipal Bond
Index, total return of 1.21%. For the same period, the average California
intermediate municipal debt fund, as measured by Lipper Inc., had a total return
of 1.80%.

Yields dropped sharply in February and March, especially on longer-term bonds.
This was caused by a combination of the U.S. Treasury buy-back program, a
slowdown of mutual fund redemptions, and a fairly light municipal supply.
Additionally, several large insurance companies are purchasing tax-exempt bonds,
so we believe that we expect to earn at least our average coupon (5 1/2%) for
the year. The average maturity of the fund now stands at 5.64 years.

The overall quality of the Fund remains high at Aa1. We have reduced our
pre/reinsured sector modestly and will look for further opportunities to
increase yields by reducing this sector in the second quarter.

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

FUND AND MANAGER REVIEW

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-month period ended March 31, 2000, the Fund had a
total return of 1.12%, as compared to the Merrill Lynch Domestic Master Index
of 2.17%. For the same period, the average corporate debt funds A-rated, as
measured by Lipper Inc., had a total return of 1.63%.

Fixed income markets improved in the first quarter of 2000 after a difficult
year in 1999. Long Treasury bonds peaked in mid-January as investors began to
look through any remaining Federal Reserve Board interest rate increases to
better times ahead. Additionally, federal budget surpluses have caused the U.S.
Treasury to take the first steps toward national debt reduction by less issuance
and direct repurchases. The combined effect of these two events created a better
market for bonds in general and U.S. Treasuries in particular.

Investment grade corporate bonds and mortgage related securities posted positive
returns but generally lagged Treasuries, especially in longer maturities. While
the weaker performance of these sectors may reflect some negative sentiment in
the market, the larger reason may have been that Treasuries were just too
popular. High yield corporate bonds were also significant underperformers in the
opening months of 2000 as mutual fund outflows put the entire sector under
pressure. One bright spot was the Fund's position in Mexico's long government
bond, which was upgraded shortly after purchase.

The portfolio is currently positioned with an emphasis on investment grade and
high yield corporate bonds in intermediate maturities. Longer bonds in the
portfolio are primarily in high quality corporate bonds and U.S. Treasuries.
Overall, the portfolio has a lower exposure to interest rate volatility and a
strong yield advantage over the market index.

With the bond market off to a good start in 2000 and inflation still under
control, investors seem to have already put 1999 behind them. Yield advantages
on corporate bonds and mortgage related bonds are near ten-year highs and
economic growth continues to provide firm support to corporate earning
potential. As such, we believe the fundamentals for corporates and mortgages are
attractive and expect them to provide investors superior returns as supply
issues in the Treasury market subside.

WILLIAM F. CAMP IS THE PORTFOLIO MANAGER FOR THE LOOMIS SAYLES CORE FIXED
INCOME FUND.

FUND AND MANAGER REVIEW

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 six-month period ended March 31, 2000, the Fund had a total return of
6.02%, as compared to the Fund's benchmark, the Lehman Brothers
Government/Corporate Bond Index, total return of 2.27%. For the same period,
the average corporate debt fund BBB-rated, as measured by Lipper Analytical
Services, had a total return of 1.88%.

Liquidity remains thin in the bond arena where, in the trailing six months, the
market experienced such event risks as fluctuations in interest rates, yield
curve inversion, U.S. Treasury buybacks, and government debt surpluses. The
close of 1999 had high yield markets offering generous returns while, in
contrast, the first quarter of 2000 was subjected to a flight to quality. In
addition to this, the Federal Reserve Board raised short interest rates three
times by 25 basis points over the period resulting in a contraction of the
bellwether 30-year Treasury bond yield to 5.83%. As a result, corporate credit
spreads widened due to higher Treasury movers and lack of an appropriate
benchmark caused by the yield curve inversion. On the foreign front, emerging
markets continued to rally, boosted by Korea's and Mexico's attainment of
investment grade status, the successful restructuring of Indonesia and Malaysia,
and Brazil's continued strong economy. The Energy and Oil sectors rallied, due
to a prolonged climb in oil prices, and convertible bonds continued to add
significant value to the Fund, buoyed by a surging equity market. In addition,
the Fund has maintained a considerable position in Canadian government and
provincial debt bonds, which is due to Canada's strong credit profile and the
call-protection these bonds provide.

There has been no change to the strategy of the Fund. We believe that this is a
good time for the Fund to opportunistically buy discounted credits with fairly
long maturities. In our view, gaining extra value through emphasizing non-market
related factors would also prove to be beneficial. The Fund will take a more
cautious approach than normal towards corporate credits due to competitive
selling pressure and lack of leverage. We believe that the Fund remains well
diversified, while offering call protection and a significant yield advantage.

DANIEL J. FUSS IS THE PORTFOLIO MANAGER FOR THE LOOMIS SAYLES FIXED INCOME FUND.

Foreign investments involve special risks including greater economic,
political and currency fluctuation risks, which may be even greater in emerging
markets. In addition, foreign countries may have different accounting standards
than those of the U.S., which may adversely affect the value of the Fund. High
yield securities are subject to a high degree of market and credit risk. In
addition, the secondary market for these securities may lack liquidity which, in
turn, may adversely affect the value of these securities and that of the Fund.

FUND AND MANAGER REVIEW

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-month period ended March 31, 2000, the Fund had a
total return of 10.20%, as compared to the Fund's benchmark, the Merrill Lynch
High Yield Master Index, total return of -0.74%. For the same period, the
average high current yield fund, as measured by Lipper Analytical Services, had
a total return of 1.27%.

There were no major shifts in portfolio strategy during the period and the
Fund performed well due to its non-market relatedness (low interest rate
sensitivity, high coupon and yield, and short maturity), its equity-related
holdings, and the continued surge of emerging market issues. In the first
three months there was apprehension with the approach of Y2K, the threat of
inflation, fluctuations in interest rates, rising yields and decreased
liquidity in the secondary markets. The most recent three months witnessed
yield curve inversion, U.S. Treasury buybacks, and government debt surpluses.
To add to this, the Federal Reserve Board raised interest rates by 25 basis
points three times over the period. On the foreign front, the emerging
markets continued to rally, boosted by Korea's attainment of investment grade
status, the successful restructuring of Indonesian and Malaysian economies,
Mexico's upgrade to investment grade status, and Brazil's continued strong
economic numbers. The Energy and Oil sectors rallied, due to a prolonged
climb in oil prices, and convertible securities continued to add significant
value to the Fund, buoyed by a surging equity market. The Fund performed
admirably well by continuing to stress its bottom-up approach, diversifying
across numerous sectors, and concentrating on convertible securities and
Yankee bonds (foreign issues denominated in U.S. dollars).

The Fund's outperformance over the past six months, in general, has been the
result of the recovery of emerging markets and strength in convertible
securities. It was also positively affected by the return to liquidity to many
of the smaller, less-known bonds we hold, in addition to some successful issue
and sector selections. As of March 31, 2000, the top holdings were RCN Corp.
(2.4%), Teligent, Inc. (2.2%), Republic of Peru (2.2%), and Republic of
Venezuela (2.1%). We believe that the Fund remains well diversified, and has
good call protection and moderate upgrade potential.

DANIEL J. FUSS IS THE PORTFOLIO MANAGER FOR THE LOOMIS SAYLES HIGH YIELD
FIXED INCOME FUND.

Foreign investments involve special risks including greater economic,
political and currency fluctuation risks, which may be even greater in emerging
markets. In addition, foreign countries may have different accounting standards
than those of the U.S., which may adversely affect the value of the Fund. High
yield securities are subject to a high degree of market and credit risk. In
addition, the secondary market for these securities may lack liquidity which, in
turn, may adversely affect the value of these securities and that of the Fund.

FUND AND MANAGER REVIEW

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-month period ended March 31, 2000, the Fund had a
total return of 2.57%, as compared to the Fund's benchmark, the Lehman Brothers
Government/Corporate Intermediate Bond Index, total return of 1.56%. For the
same period, the average intermediate investment grade debt fund, as measured by
Lipper Inc. had a total return of 1.61%.

The fiscal year began with apprehensions of Y2K, the threat of inflation,
fluctuations in interest rates, rising yields and decreased liquidity in the
secondary markets. With an equity-driven environment and a flattening yield
curve, bond market sentiment was negative. Then new millennium witnessed yield
curve inversion, U.S. Treasury buybacks, and government debt surpluses. While
Treasury bond prices moved higher, corporate securities lagged. Corporate yield
spreads moved significantly wider as investors in this sector established a more
defensive posture in response to increasing concerns about event risk and
liquidity. Importantly, the wider spreads in the corporate sector largely
reflect diminished demand from traditional buyers rather than a broad
deterioration in average credit quality.

Oil and gas sectors had positive returns as higher oil prices boosted the
industry. Yankee bonds (foreign issues denominated in U.S. dollars) proved to be
beneficial to performance, in particular Industrial Finance Corp. of Thailand.
Agency markets were unsettled as a result of recent talk of tighter regulations
on government-sponsored enterprises (GSEs). Investors pulled money away from
agency debt and moved to U.S. Treasury securities resulting in a widening of
agency spreads.


The wider corporate bond yield spreads, which materialized during March, have
created several interesting "buy" opportunities. Since the Fund has a "value"
orientation, we are constantly seeking securities which we believe are priced
below their intrinsic values based on our internal fundamental analysis. We
believe that the lagging performance of corporate bonds relative to Treasury
securities has resulted in more attractive valuations for this sector of the
market. We will continue to focus on identifying undervalued credits in an
attempt to create a flexible balance between high current income with the
potential for capital appreciation.


ANTHONY J. WILKINS IS THE PORTFOLIO MANAGER FOR THE LOOMIS SAYLES
INTERMEDIATE DURATION FIXED INCOME FUND.

FUND AND MANAGER REVIEW

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-month period ended March 31, 2000, the Fund had a
total return of 5.56%, as compared to the Fund's benchmark, the Lehman
Brothers Government/Corporate Bond Index, total return of 2.27%. For the same
period, the average corporate debt fund BBB-rated, as measured by Lipper
Inc., had a total return of 1.88%.

There were no changes in portfolio strategy over the period and the Fund
maintains its long-term investment strategy of buying longer, discounted
corporate bonds for the added yield and call protection they provide. During
the first three months of the fiscal year, there was apprehension with the
approach of Y2K, the threat of inflation, fluctuations in interest rates,
rising yields and decreased liquidity in the secondary markets. The most
recent three months witnessed yield curve inversion, U.S. Treasury buybacks,
and government debt surpluses. To add to this, the Federal Reserve Board
raised interest rates by 25 basis points three times over the period. On the
foreign front, the emerging markets continued to rally, boosted by Korea's
attainment of investment grade status, the successful restructuring of
Indonesian and Malaysian economies, Mexico's upgrade to investment grade
status, and Brazil's continued strong economy. The Energy and Oil sectors
rallied, due to a prolonged climb in oil prices, and convertible securities
continued to add significant value to the Fund, buoyed by a surging equity
market. The Fund performed admirably well by continuing to stress its
bottom-up approach, diversifying across numerous sectors, and concentrating
on convertibles and Yankee bonds (foreign issues denominated in U.S.
dollars).

The Fund's outperformance over the past six months can be attributed to its
large positions in convertible securities, emerging markets securities, and
Yankee bonds. It was also positively affected by the return of liquidity to
many of the smaller, less-known issues we hold, in addition to some
successful issue and sector selections. As of March 31, 2000, the top
holdings were Loews Corp. (3.5%); Canadian Government (3.5%); Tenaga Nasional
Berhad (2.9%); and Atlas Air Inc. (2.3%). We believe that the Fund remains
well diversified and has good call protection and moderate upgrade potential.

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

Foreign investments involve special risks including greater economic, political
and currency fluctuation risks, which may be even greater in emerging markets.
In addition, foreign countries may have different accounting standards than
those of the U.S., which may adversely affect the value of the Fund. High yield
securities are subject to a high degree of market and credit risk. In addition,
the secondary market for these securities may lack liquidity which, in turn, may
adversely affect the value of these securities and that of the Fund.

FUND AND MANAGER REVIEW

LOOMIS SAYLES PROVIDENT FUND
-------------------------------------------------------------------------------

The Loomis Sayles Provident Fund attempts to achieve long-term growth of
capital. For the six-month period ended March 31, 2000, the Fund had a total
return of 22.31%, as compared to the Fund's benchmark, the S&P 500 Index total
return of 17.51%. For the same period, the average large-cap core funds, as
measured by Lipper Analytical Services, had a total return of 21.66%

The fourth quarter of 1999 began with a continuation of the same trends that
made the third quarter so difficult with the strengthening world economy and
the huge trade deficit putting the dollar, the bond market, and the stock
market under pressure. Our strategy of reduced exposure to very highly valued
technology stocks and an above normal position in cash was looking good. All
this changed on Monday, October 18th, when the Commerce Department reported
the August trade deficit at $24.1 billion versus a consensus expectation of
$25.0 billion, flat with the July number. This launched a powerful rally in
the bond market and a technology driven run in the stock market. A week later
a less robust than expected September durable goods orders and a Labor
Department report showing almost no growth in wages fueled further gains in
both the bond and the stock markets. Although the bond market rally lasted
only a month and has since far more than retraced itself, stocks continued to
set new highs for the remainder of the year.

This year the first quarter began with an abrupt reversal of the pattern of
strength in technology stocks and weakness in nearly everything else which
characterized the fourth quarter from mid-October on. From a fundamental
perspective this shift made sense. Valuations of technology stocks had
reached levels that were all but impossible to rationalize while the
gathering strength of the world economy and the success of OPEC in
stabilizing oil prices made other sectors more attractive. However, this new
pattern did not prevail for very long into January. As 401(k) plan
participants and defined benefit plan sponsors shifted assets from more
diversified and/or value oriented managers to technology sector funds and
growth managers with a heavy emphasis on technology, the market reverted to
its earlier pattern with technology once again the unchallenged leader.

By beginning the quarter with a slightly greater than market weighting of 32% in
technology, cutting back as that sector began to decline, and first reducing and
then rebuilding positions in the more cyclical sectors, we were able to keep the
Provident Fund ahead of this treacherous market. Several technology stocks
including Corning Glassworks, Analog Devices, Advanced Micro Services, and Ciena
were our best performers with two energy stocks - Baker Hughes and Vastar - also
doing well. Our weakest holdings were concentrated in the commodities sector,
and included International Paper, Unocal, Dow Chemical, and Praxair.

Looking ahead, I can only describe the current environment as being as complex
and confusing as I have ever dealt with in 35 years in this business. The
structural changes in our business plus the advent of internet trading and chat
rooms and the all day cable coverage of the market have created a momentum
driven market which causes moves both up and down in individual stocks and
sectors to an extreme never seen before. Further complicating the situation is
the fact that the market itself is now having an important impact on the
economy. Finally, the international economy, while in many respects much
improved, remains unstable with huge and rapidly growing U.S. current account
deficits being funded by vast funds flows from our trading partners into our
financial markets. In this environment agility seems to be the only defense.
This necessitates high turnover with moves in and out of the volatile and
dominant technology sector being a recurring event. I have also tended to run
larger than normal cash positions and to quite consistently hold a large
position in North American natural gas oriented stocks where the supply and
demand prospects seem truly compelling and still underappreciated.

FUND AND MANAGER REVIEW

LOOMIS SAYLES SMALL COMPANY GROWTH FUND
-------------------------------------------------------------------------------

The Loomis Sayles Small Company Growth Fund attempts to achieve long-term
capital growth by investing in the shares of smaller companies experiencing
rapid growth. For the six-month period ended March 31, 2000, the Fund had a
total return of 83.29%, as compared to the Fund's benchmark, Russell 2000 Growth
Index, total return of 45.77%. For the same period, the average small-cap growth
fund, as measured by Lipper Inc., had a total return of 65.68%. We attribute
this strong absolute and relative performance to two key factors, the Fund's
significant position in technology stocks and favorable stock selection.

The Fund remained fully invested with less than 5% cash throughout the period.
As you know, this is our normal practice in good times or bad. Rather than
trying to "time the market", we focus on trying to build and manage the
portfolio from the bottom up, investing in the strongest small cap growth
companies we can find. We expect to maintain this strategy in the coming months
despite the increasing market volatility.

The past six months was a period of strong performance for small cap stocks
particularly the shares of growth companies. Investors became enamored with
technology stocks in part because the near term fundamentals were, and still
are, very strong and in part due to the long-term growth potential the Internet
represents for these companies. Several of the Fund's technology holdings gained
more than 100%. Kopin Corp., a manufacturer of miniature electronic displays and
specialty semiconductor wafers, gained 395.5% from September 30, 1999 to March
31, 2000.

The advance was not just traditional technology but biotechnology as well. In
the last several months tremendous progress has been made in mapping the human
genome. Genomics holds great promise in medicine. There are a number of
companies focused on developing new treatments utilizing gene therapy. As this
progress became more apparent in the fall of 1999, investors started to focus on
the opportunities these companies presented. Genelogic, a supplier of genomics
data used in drug discovery by pharmaceutical companies, advanced 178.5% after
our initial purchase in early December.

The level of returns of the past six months experienced by the Fund as well
as other investors was unprecedented. Clearly, despite all the good
fundamental news, stocks could not keep rising indefinitely without some kind
of adjustment. As of the writing of this letter in mid-April, we remain in
the midst of a significant market correction. The valuations of small and mid
cap growth stocks have been hit the hardest. The volatility we have
experienced since early March has been significantly higher than the norm. It
is our view that this correction and the associated volatility may continue
for some time. There is a silver lining to this correction, however. First,
it was very clear that valuations had reached unsustainable levels by early
March. The process of bringing those valuations to more reasonable levels is
well underway. Second, corrections provide us the opportunity to invest in
stocks that were either too big or too expensive prior to the correction.
This process of upgrading is now underway and will continue as opportunities
develop. Finally, we are mindful of the fact that economic growth remains
robust and the likelihood of further Federal Reserve Board moves to raise
interest rates remains high. However, we also believe that economic growth
has begun slowly to more reasonable levels, that the Federal Reserve Board
will complete its interest rate moves probably in the first half of the year,
and that as a result, the environment for equities should remain positive for
at least the balance of 2000.

The Fund's strong performance was attributable to unusually favorable
conditions that are not likely to be sustainable, including strong weightings in
the technology and consumer sectors, and investments in initial public
offerings (IPOs).

Foreign investments involve special risks, including greater economic,
political and currency fluctuation risks, which may be even greater in
emerging markets. In addition, foreign countries may have different
accounting standards than those of the U.S., which may adversely affect the
value of the Fund. Small and mid-cap stocks may be more volatile and subject
to wider value fluctuations than larger, more established companies. The
secondary market of small and mid-cap stocks may be less liquid, or harder to
sell, which could also adversely impact the Fund's value.

FUND AND MANAGER REVIEW

LOOMIS SAYLES SMALL COMPANY VALUE FUND
-------------------------------------------------------------------------------

The Loomis Sayles Small Company Value Fund attempts to achieve long-term
capital growth. For the six-month period ended March 31, 2000, the Fund had a
total return of 17.97% as compared to the Fund's benchmark, Russell 2000
Index, total return of 26.83%. For the same period, the average small-cap
value fund, as measured by Lipper Analytical Services, had a total return of
12.87%. The Fund's underperformance against the Russell 2000 for the past six
months is almost entirely due to the huge disparity of returns between growth
and value style investing during this period. Since September 30 1999, the
Russell 2000 Growth component has returned 45.77%, compared to 5.41% for the
Russell 2000 Value Index. In particular, our valuation discipline resulted in
the Fund being underweight in the technology and healthcare sectors, which
until late in the first quarter of this year had afforded unprecedented
returns in a short period of time.

The past six months have been a period of great volatility and rapid and extreme
changes in sentiment for equity investors. They began with growth oriented
issues, notably evidenced by the technology sector and biotechnology industry,
out-performing the broader market by a wide margin. However, this long-standing
pattern, which was particularly pronounced in the fourth quarter of 1999,
shifted dramatically in March of this year as a sharp correction ensued in many
of the market's leadership groups. The correction began in the biotechnology
sector and ultimately encompassed a majority of what had been the highflying
technology groups, with declines reaching as much as 50% for a wide range of
individual stocks and industries. Coincidental with the sell-off in growth, a
number of "old economy" industries rallied, in some cases sharply. The net
effect was that for the first time in months, value-style investing returns in
March significantly exceed growth returns in the small-cap arena.

During this period we have not changed our overall investment strategy. We have
modestly re-positioned the portfolio over the past six months to give
recognition to the dynamic forces in the economy and the market that have been
driving results. In this regard, we added late last year to the portfolio's
weight in technology and healthcare. However, we have done so while remaining
focused on the consistent application of our long-standing disciplined value
strategy. The portfolio ended the first quarter at a greater than 20% discount
price-earnings ratio versus the Russell 2000. We have also maintained and
improved upon the fundamental character of the portfolio. Finally, we have
modestly reduced the number of holdings in an effort to more meaningfully
emphasize the most attractive stocks.

During the past six months the best performing sectors were technology and
healthcare. On a relative basis, the best performing sectors were energy and
materials and processing. The Fund is broadly diversified across all of the
Russell economic sectors.

As we move into the second quarter, we are optimistic that the vast performance
disparity between value and growth-style investing will continue to narrow. In
an uncertain market environment and over the long term, we believe investors
will migrate toward companies with solid growth prospects, tangible earnings and
cash flow, and more reasonable valuation metrics. In addition, after a long
period of underperformance, small-cap stocks appear poised for better returns
given the attractive valuation of the sector and solid earnings potential for
smaller companies in the coming year. In this regard, we believe the portfolio
is well positioned on all counts.

Foreign investments involve special risks including greater economic, political
and currency fluctuation risks, which may be even greater in emerging markets.
In addition, foreign countries may have different accounting standards than
those of the U.S., which may adversely affect the value of the Fund. Small and
mid-cap stocks may be more volatile and subject to wider value fluctuations than
larger, more established companies. The secondary market of small and mid-cap
stocks may be less liquid, or harder to sell, which could also adversely impact
the Fund's value.

NOTE: PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE. IT IS NOT
POSSIBLE TO INVEST IN AN INDEX.

NOTES TO FINANCIAL STATEMENTS
-------------------------------------------------------------------------------
MARCH 31, 2000 (UNAUDITED)

1. Loomis Sayles Investment Trust (the "Trust") consists of nine 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 Fixed Income Fund
Loomis Sayles High Yield Fixed Income Fund
Loomis Sayles Intermediate Duration Fixed Income Fund
Loomis Sayles Investment Grade Fixed Income Fund
Loomis Sayles Provident Fund
Loomis Sayles Small Company Growth Fund
Loomis Sayles Small Company Value 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. 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

<PAGE>

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 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 counter parties 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.

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


                                                                             104
<PAGE>

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 March 31, 2000, 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 issue discount
bonds, 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,
Fixed Income, High Yield Fixed Income, Provident, Small Company Growth and Small
Company Value 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 securities contributed or redeemed-in-kind, foreign currency
transactions, capital loss carryforwards, deferred

<PAGE>

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.

2. PURCHASES AND SALES OF SECURITIES -- (excluding short-term investments) for
each Fund for the six months ended March 31, 2000 were as follows:

(1) ON NOVEMBER 9, 1999, THE BOARD OF TRUSTEES OF THE TRUST VOTED EFFECTIVE
    DECEMBER 1, 1999 TO LOWER THE CORE FIXED INCOME FUND'S MANAGEMENT FEE FROM
    0.50% TO 0.35% THEREBY DECREASING THE MAXIMUM OPERATING EXPENSE RATIO FROM
    0.65% TO 0.50%.

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 Core Fixed Income Fund may invest up to 10%, the Fixed
Income Fund may invest up to 35%, the High Yield Fixed Income Fund will invest
at least 65%, and the Investment Grade Fixed Income Fund may invest up to 10% of
its total 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.
