DEAR FELLOW SHAREHOLDER:


CONTINUED IMPROVEMENT IN PERFORMANCE

     We are happy to report that for the fiscal year ended May 31, 2000, most of
the Westcore Funds outperformed, or were very close to their representative
Lipper Mutual Fund Index of similar funds, which are described in further detail
in each Fund's report. However, outperforming the appropriate benchmark indexes
for each Fund continues to be a challenge. We have summarized the annual total
return1 for the fiscal year ending May 31, 2000 of the Funds ranked highest to
lowest, and indicated how each compared to the Lipper index of similar funds and
the appropriate benchmark.

(1)  Annual total return represents past performance. Past performance is not
     indicative of future results. Performance information for periods of less
     than one year are less meaningful than longer performance history. Annual
     total return reflects reinvestment of dividends, capital gains
     distributions, all fee waivers and expense reimbursements. Without the fee
     waivers and expense reimbursements, the Funds' annual total return would
     have been lower. Investment return and principal value will fluctuate, and
     shares, when redeemed, may be worth more or less than their original cost.

     The array of performance provides several messages. First, the year ended
May 31, 2000, was a very unique time period given the large returns achieved for
growth investing, particularly after several years of a bull market. We are
pleased that our research-intensive approach was able to capture these returns.
The year also included one of the best IPO markets in history, which several of
our equity funds took advantage of to meaningfully enhance their returns.
Second, our three new funds, the Westcore Select, Small-Cap Growth, and
International Frontier Funds increased our offerings. We added these funds to
take advantage of a broader market and to create exposure to additional
investment styles that provide the opportunity for long-term outperformance. The
early investment results support this, as you can see from the summary above.
Third, while there was some broadening of the market towards small and mid-cap
stocks, the environment for value investing remained difficult. This has been
caused by the great strength in "New Economy" industries. However, we believe we
may be entering a more level playing field which we talk about below.


MARKET AND ECONOMIC ENVIRONMENT

     During the calendar year 2000, we have seen two distinct market
environments. After a strong fourth quarter in 1999, growth stocks continued to
outperform through early March. At that time, the Federal Reserve's interest
rate hikes caught up with the market and caused a meaningful correction. The
brunt of this correction was focused on growth stocks, as their high valuations
were unsustainable in the face of rising interest rates. It was then that we
began to see better performance from value stocks whose valuations were already
low compared to historical norms. We believe this is signaling the end of last
year's blanket outperformance of "anything.com" stocks and that going forward
company prospects and fundamentals which are supported by reasonable valuations
will drive performance for both growth and value stocks.

     As for the overall market, we are now in a mode of "watching and waiting"
to see if the Federal Reserve can successfully slow the economy enough to reduce
inflation without creating a recession. The next few months will be a test, with
simultaneous signs that the economy is slowing combined with difficult inflation
comparisons as energy prices continue at high levels over the summer. We believe

that by fall, the Fed will succeed, due to both early Fed action and to the
private economy's ability to produce exceptional productivity gains. Success
would mean a soft landing for the economy with growth estimates near 4% and low
inflation.

     In this environment, we believe that corporate profits should continue to
grow nicely and stocks should continue to provide good performance, albeit
likely at a slower pace than we have seen in the last 12 months. Contained
inflation, along with continued government budget surpluses, may allow for
eventually lower interest rates, providing good returns for bonds.

     In the following pages, each of the Funds' portfolio managers report on
their performance and strategies. Investors in the Westcore Long-Term Bond and
Intermediate-Term Bond Funds should note that we are restructuring these funds
effective October 1, 2000. We are pleased with the upcoming changes, because we
believe that the new funds will offer you bond investments that will better suit
your investment needs. The Prospectus Supplement dated July 28, 2000 explains
the changes in detail. For more information, visit www.westcore.com where you
can also meet each of the portfolio managers and hear portfolio updates.

     We would like to thank all of our investors for your confidence in
Westcore, and to especially welcome investors to the three new funds introduced
last year.

     MIDCO Growth Fund


     Westcore MIDCO Growth Fund's total return for the fiscal year ended May 31,
2000 was 35.63%, compared to 43.72% for the Russell Midcap Growth Index and
33.86% for the Lipper Multi-Cap Growth Index. The year was challenging because
of stock price volatility. Our investment performance came primarily from
technology and biotech stocks that peaked early in March--then fell sharply,
appearing to bottom early in May. During this period of decline from mid-March
to the middle of May, the Nasdaq Index was down 41%--its second worst decline
since its inception in the early '70's. We were ahead of our benchmark going
into the decline. However, our stocks came down more in the decline and we ended
the fiscal year behind the Russell Midcap Growth Index.

     We continue to have meaningful exposure to technology stocks in the
portfolio. Vignette and Network Appliance are two holdings in our portfolio that
illustrate how strong business is for many companies in this sector. Vignette
makes software for companies needing a robust website, and its March quarter
sales were up 500% over last year. Network Appliance makes high-performance
network-attached storage devices, and sales for the March quarter were up 120%
year-over-year. These companies--and many more in our portfolio--are
experiencing remarkable growth which I expect to continue for the next few
years.

                                "...THE COUNTRY'S
                                ECONOMIC HEALTH
                                 IS STRONG AND

     In my mind, an important inflection point will be reached when 25% of
Americans can get movies on demand on their television sets. Video is data
intensive and will use an incredible amount of bandwidth and data storage. I
expect that the rate of growth of the infrastructure build-out should peak at
that point.

     Specialty retailing stocks, such as Abercrombie and Fitch and Nordstrom,
were disappointing. Last fall, these stocks looked attractive due to their
valuation levels, but unfortunately earnings did not come through. This was due
partly to changing fashion trends and partly to the increase in gas and oil
prices--simply because the consumer who must pay more for a necessity like
gasoline has fewer dollars to spend on apparel.

     It is my belief that, while the last few months have been painful, the
market volatility felt by investors has actually been healthy. This market
correction reminds us that the outstanding returns we have all enjoyed are
simply not realistic. We do appear to be through the worst of it, and hopefully
our return expectations have become more reasonable. At the same time, the
country's economic health is strong and providing growth opportunities for many
medium-sized companies.

The Russell Midcap Growth Index measures the performance of those Russell Midcap
companies with higher price-to-book ratios and higher forecasted growth values
than in the Russell 1000 index.

The Lipper Multi-Cap Growth Index is an unmanaged index comprised of the 30
largest mutual funds in the Lipper Multi-Cap Growth Funds classification. This
classification consists of funds that concentrate no more than 25% of their
equity assets in any one market capitalization range over an extended period of
time. Multi-Cap Growth funds will generally have between 25% to 75% of their
assets invested in companies with long-term earnings growth expectations that
have market capitalizations (on a three-year weighted basis) above 300% of the
dollar-weighted median market capitalization of the S&P Mid-Cap 400 Index.

An investment cannot be made directly in an index.

  Milford H. Schulhof, II
Portfolio Manager, Westcore
  Growth and Income Fund


     I am pleased to report that the Westcore Growth and Income Fund had a very
good year, gaining 44.88% for the fiscal year ending May 31, 2000. In
comparison, the S&P 500 returned 10.56% and the Lipper Multi-Cap Growth Index
returned 33.86% for the same time period.

     Technology continued to play a significant part in our return. Although the
tech sector was, in general, weak at the end of the fiscal period, many of our
holdings in this area finished the year ahead of their beginning values. Intel
is an example of a holding that has done particularly well. Intel, the leading
manufacturer of microprocessors, is benefiting from the huge increase in demand
for personal computers. Their Pentium chips are everywhere, and as computers
increasingly find their way into more and more homes throughout the country, I
believe Intel will enjoy a very strong tailwind.

     I did, however, trim our technology holdings from our last report. After
the huge gains in this area, I felt that valuations became excessive and it made
sense to lock in profits and reduce the risk of the portfolio by decreasing our
exposure to this very volatile sector. I made the change at the beginning of the
calendar year--a move that, in hindsight, proved to be good timing.

                               MANAGER'S OVERVIEW


                                   "AS ALWAYS,
                                 WE CONTINUE TO
                                 LOOK FOR GREAT
                                 COMPANIES WITH
                               GOOD GROWTH RATES
                                 AT ATTRACTIVE
                                  VALUATIONS."


     Encouraged by strong oil prices, we have moved the portfolio into an
over-weighting in energy. Enron, a wholesaler of electricity and natural gas, is
an example of a company benefiting not only from the increase in prices, but
also from changes within their industry. Enron has moved into the energy
marketing area--in effect becoming wholesalers of electricity, acting as the
middleman between utilities in need of extra power and utilities with surplus
power.

     One holding I am cautious about is Lowe's. Though their earnings are
increasing at a good rate--about 20%--some investors are questioning their
recent acquisition of Eagle Hardware, and whether the two businesses are being
integrated smoothly. Also, investors are watching the increase in interest rates
and how that affects the building market--a major market for Lowe's. But, I'm
optimistic that Lowe's will benefit when the Federal Reserve eases its interest
rate focus.

     As always, we continue to look for great companies with good growth rates
at attractive valuations. Unemployment and inflation are low, the budget remains
in surplus, corporate earnings are expanding at a very healthy pace, and
interest rates, I believe, will stabilize sometime in the coming year. The
backdrop for investing is very positive. We've seen a lot of profit taking in
the market which has driven it down, but I believe it will stabilize and that we
will resume the bull market that has been in place for years.

This Fund participates in the Initial Public Offering ("IPO") market, and a
significant portion of the fund's returns have been attributable to its
investment in IPOs, which in turn have had a magnified impact due to the fund's
relatively small asset base. As the Fund's assets continue to grow, it will be
increasingly less likely to experience substantially similar performance by

  Michael W. Gerding, CFA
Portfolio Manager, Westcore
International Frontier Fund


     Since inception on Dec. 15, 1999 through the end of the fiscal year,
Westcore International Frontier Fund was up 16.12%, which compares favorably to
its indexes. During the same period, the MSCI World Ex-US Small Cap Index was
down 2.17%, and the Lipper Small-Cap International Index was up 1.33%.

     The period through May 31, 2000 provided sharp contrasts for U.S.
investors. Performance, market sentiment, and market expectations all moved from
one extreme to the other in the first five months of 2000. These factors also
impacted small companies outside the U.S., creating a very difficult investing
environment for the first five months of the Fund's life. Fortunately for the
Fund, the positives outweighed the negatives. In particular, our overweight
position in Europe helped the Fund, as did our large exposure to the healthcare
and oil services industries. And, although technology was the most volatile
industry during the period, our exposure there added to the performance of the
Fund in general. On the negative side, our Japanese position hurt the Fund. The
good news is that the Fund was underweighted in Japan. Also, most of our
consumer-oriented companies did not help the Fund. The dollar strengthened in
the first five months, and as we were not hedged, it negatively impacted the
performance of the Fund.

     The healthcare products and semiconductor capital equipment industries were
particularly strong for us in the period. Angiotech, a Canadian developer of
cardiology products, and Phonak, one of the world's leading manufacturers of
hearing aids based in Switzerland are two examples of healthcare companies that
contributed to the performance of the Fund. Semiconductor companies are rapidly
increasing their spending to create new capacity to meet the strong demand for
their products. In addition, they are introducing new production

lines to produce new, leading edge semiconductors. The combination of these two
trends has greatly improved the prospects for the semiconductor capital
equipment companies. The two that we own, ASM International from the
Netherlands, and SEZ Holdings from Switzerland, both benefit from this, as well
as the fact that they make state of the art equipment, which is allowing them to
gain market share in a growing market.

     Westcore International Frontier Fund utilizes a time tested approach to
seek small companies outside the U.S. that are growing faster than the country
in which they are located, faster than the industry in which they participate,
and ideally faster than they have historically. We also try to make sure we are
paying attractive prices for these rapidly growing businesses. We build our
portfolio from the bottom up, regardless of where they are located. We are not
constrained by top down regional, country, or industry models that might force
us to invest in companies that we feel are less than the best.

     Looking forward, the balance of 2000 is likely to continue to be impacted
by macro factors in the market. But we believe that the economic growth we are
seeing outside the U.S. will lead to better earnings growth for small companies,
which will provide more opportunities for us. This, coupled with the correction
in prices we have seen in most companies, creates an attractive opportunity to
buy great, rapidly growing businesses at attractive levels.

  Small-Cap Growth Fund

    Westcore Small-Cap Growth Fund's total return from its inception on October
1, 1999, to the end of the fiscal year, May 31, 2000, was 70.11%, strongly
outpacing the Russell 2000 Index at 12.25% and the Lipper Small-Cap Growth Index
at 35.89% for the same period.

    Our noteworthy performance masks two very different markets during this
period. From the Fund's inception into early March, we had a very strong market
and the Fund was up well over 100%. Technology stocks and several successful
Initial Public Offerings (IPOs) can be given credit for the lion's share of the
return. For example, Power Wave Technologies, a manufacturer of amplifiers that
send signals to wireless phones, nearly quadrupled in price from where we
purchased it due to strong volumes and a significant contract to supply Motorola
with their product. Interwoven, a company whose software manages content
distributed on the web is up 260% from its IPO in October.

                               MANAGER'S OVERVIEW

                              "...SMALL COMPANIES
                              ...HAVE JUST GOTTEN
                               CHEAPER, GIVING US
                               MORE OPPORTUNITIES
                              TO FIND GREAT LITTLE
                               COMPANIES AT MORE
                              REASONABLE PRICES."


    The second period, mid-March through the end of our fiscal year, was very
negative for small-cap growth stocks in general, and technology stocks in
particular, which have been a strong theme in the Fund since it began. For
example, On Display, a dynamic content aggregation company was down over 50%
from its March highs. This is indicative of the small-cap tech sell-off.

    The heady gains and subsequent drop illustrate a characteristic of this
Fund--volatility. I like to remind investors that, while over the short-term,
volatility can be stressful, over the long-term, it can create great potential
for above average returns. I believe this Fund is a great option for the more
aggressive, long-term portion of your investment portfolio.

    My outlook for small-cap growth stocks is positive. The growth areas for
small companies have not changed with this downturn--they have just gotten
cheaper, giving us more opportunities to find great little companies at more
reasonable prices. It's also beginning to look like the Federal Reserve's
actions are finally moderating economic growth--leading me to believe the
interest rate increases are coming to an end, and that is positive for the small
companies in this Fund.

Fund has posted an outstanding 134.33% total return as of May 31, 2000. In
comparison, the S&P 500 returned 11.64% and the Lipper Multi-Cap Core Index
returned 16.28% for the same time period.

    The key to this Fund's out-performance this period is flexibility. We
created this Fund to be nimble so that we could respond quickly as markets
changed and new themes and opportunities emerged. This enabled us to benefit
from strong areas and to preserve our gains when the environment turned.

    During the first five months of operation, we took advantage of a very
strong market environment, several successful Initial Public Offerings and an
over-weighted exposure to the technology and media sectors. Stocks of particular
strength included ProsoftTraining.com, a global internet solutions company that
provides curriculum and skills-based Internet certification programs, and
Westwood One, a programming and information supplier to radio and television
stations.

                                  "WE WANT TO
                                  OWN WHAT WE
                                 CONSIDER TO BE
                               THE BEST COMPANIES
                                 WITH EXCELLENT
                                GROWTH DYNAMICS,
                               STRONG FUNDAMENTAL
                                  DRIVERS AND
                             REASONABLE VALUATIONS,
                             REGARDLESS OF SECTOR."


    The following three months, beginning in March, brought a very difficult
market environment as valuations, particularly in the technology area, corrected
significantly over a short period of time. As the market began to trend
downwards in early March, we shifted our emphasis away from technology and
growth and looked for high quality companies with good growth potential at more
modest valuation levels. We purchased highly liquid and quality holdings such as
Maytag, Starwood Hotels, Aetna, and BJ Services.

    Looking ahead, we expect the markets' volatility to continue. The
significant interest rate increases over the past year have begun to slow the
economy, which will affect earnings particularly during the second half of 2000.
Even though we believe the Fed is near the end of its rate increases, we believe
that the impact the actions have had on the economy will be felt for the next
six months.

    As a result of these volatile times, we have taken a more balanced approach
to constructing the portfolio. As we sift through the debris of the technology
decline, we are finding and beginning to accumulate great companies at
significantly more attractive valuations than in the prior six months. We want
to own what we consider to be the best companies with excellent growth dynamics,
strong fundamental drivers and reasonable valuations, regardless of sector. We
also have ample amounts of cash enabling us to take advantage of what we view as
unusual investment opportunities. We find these to be exciting times, where we
believe that our research will make a difference.

WESTCORE BLUE CHIP FUND

FUND OBJECTIVE: Seeks to maximize long-term total return by investing in stocks
of large, well-established companies whose stocks appear to be undervalued.

    Portfolio Manager,
 Westcore Blue Chip Fund


    The total return for Westcore Blue Chip Fund for the fiscal year ended May
31, 2000 was 1.01%. In comparison, the S&P 500 Index returned 10.56% and the
Lipper Multi-Cap Value Index was down 1.51%.

    The under-performance relative to the S&P500 Index was primarily a result of
investors continuing to favor growth stocks over value stocks for most of the
fiscal year. However, this trend began to reverse in March and we believe value
stocks will continue to outperform going forward. We were also overweighted in
financials, and underweighted in technology--both of which hurt us for most of
the year but turned out very positive as the market changed in mid-March.

    In the early part of 2000, we made the decision to raise our exposure to
energy, especially in natural gas, because we believed the recent higher prices
would last longer than commonly anticipated. We have some interesting companies
in our portfolio benefiting not only from the favorable market environment, but
because they are moving their businesses in new directions. For example, Dynegy
is a company that is consistently increasing the part of their business that is
not regulated--and therefore more profitable--by marketing natural gas to large
companies. Coastal Corp. is merging with El Paso, a company that has been a
leader in laying fiber optic cable through their natural gas pipelines, and as a
result has one of the largest networks of this type.

                               MANAGER'S OVERVIEW

                          "LONG-TERM, I AM OPTIMISTIC
                           ABOUT THE OPPORTUNITY FOR
                             STOCKS IN GENERAL, AND
                        FOR VALUE STOCKS IN PARTICULAR."


    We have recently added to our financial stocks, because we believe we are
nearing the end of interest rate increases and financials tend to do well in
stable or declining interest rate environments. Also, the valuations in the
financial sector are compelling. Property and casualty insurer ACE Limited has
done very well as property and casualty rates have improved. The company is also
successfully integrating the acquisition of CIGNA's property and casualty
business into its own. We participated in the IPO of MetLife this year, and that
also performed well.

    A stock that disappointed us was Novell, who warned of an earnings
disappointment due to poor top-line growth in packaged software sales. We sold
the stock until the demand picture becomes clearer. Office Depot also warned of
poor results due to slower sales and a shift in favor of lower-margined
technology products. We are holding the stock for the time being.

    Long-term, I am optimistic about the opportunity for stocks in general, and
for value stocks in particular. Our value team will continue to employ the same
philosophy and disciplines in building a portfolio of attractively-valued,
large-cap stocks. Importantly, we have refined our research processes this year,
placing more emphasis on fundamental research geared toward fully understanding
a company--its products, management, financial model, etc--and requiring a
catalyst for unlocking the value in the company.

WESTCORE MID-CAP OPPORTUNITY FUND

FUND OBJECTIVE: Seeks to maximize long-term capital appreciation by investing

    Christianna Wood, CFA
     Portfolio Manager,
Westcore Mid-Cap Opportunity Fund


    Westcore Mid-Cap Opportunity Fund gained 31.08% for the fiscal year ended
May 31, 2000, strongly outpacing the returns for the Russell Midcap Index of
13.26% and the Lipper Mid-Cap Value index of 9.14%.

    Value investing was a difficult area for most of our fiscal year; however,
we were able to outperform our indexes due to a significant shift in our stock
selection strategy. In the third quarter of 1999, we switched to what I refer to
as a "relative value approach." This approach enabled us to consider good
companies in sectors that aren't traditionally thought of as value areas, such
as technology. By focusing on those stocks that were cheaper on a relative basis
in the areas of the market that were performing well, we were able to drive our
returns well ahead of the indexes. Before the market corrected, we underweighted
our technology holdings and shifted to more conservative tech holdings--a move
that preserved our gains nicely.

    We also participated in the IPO market and made some successful decisions
here. For example, Finisar, a maker of fiber optic networking equipment,
performed extremely well due to the fact that it was a profitable company, was
relatively undervalued and produced a good product in a rapidly growing
industry. Finisar more than quadrupled in price from where we purchased it.

                                 "I BELIEVE THAT
                                ECONOMIC FACTORS
                                   ARE COMING
                                  TOGETHER TO
                                 INDICATE THAT
                                VALUE IS ON THE
                                CUSP OF TURNING
                                    AROUND."

     An example of a strong performer in our portfolio that was not an IPO is
Dynegy, an independent power producer. Dynegy is taking advantage of new
opportunities being created by an industry rapidly becoming deregulated by
building natural gas-fired generating plants.

     Unfortunately, not all of our stories were good this year. One of our more
disappointing purchases was Conseco, an insurance company. The outlook for
Conseco was very positive following a merger with a consumer finance company and
the synergies expected there. However, the stock rapidly lost value when
investors lost confidence in some of its business practices.

     Overall, I am very enthusiastic about the outlook for mid-cap value stocks.
I believe that economic factors are coming together to indicate that value is on
the cusp of turning around. We have seen a peak in the bull market and in
economic earnings growth, and a deceleration in the rate of economic growth.
There is a large disparity in the price-to-earnings ratio ("P/Es") of sky-high
growth and bottomed-out value stocks--a condition that naturally tends to
correct itself, moving the extremes back to the middleground. We are, in fact,
at a place in time where the P/Es of value companies are the cheapest we have
seen in 25 years, which is a great time to be a value investor.

     For the fiscal year ended May 31, 2000, Westcore Small-Cap Opportunity
Fund's total return was 0.20% versus 9.9% for the Russell 2000 Index and 2.78%
for the Lipper Small-Cap Value Index.

     Most of the fiscal year was difficult for value stocks, as illustrated in
the disparity of over 10 percentage points between the Russell 2000 Index, which
includes both growth and value stocks--returning 9.9%--and the Russell 2000
Value Index, representing only the value portion of the index--down 0.26%.

     As we came into the year 2000, we made the decision to position the
portfolio so that it would perform well when the market corrected by
underweighting technology and overweighting finance, healthcare and energy. In
March of this year, the anticipated change in the market occurred and the shift
was decidedly in favor of value stocks and away from the high flying, often
profitless technology, internet and telecommunication stocks. As a result, our
performance deficit began to lessen as we closed out the fiscal year.

     The technology stocks we did own, however, performed extremely well. We
emphasized stocks that were less risky and generated profits, such as
semiconductors and software companies. International Rectifiers, a company that
makes power semiconductors for lighting, is an example of a holding that
performed well. Others are Symantec, a company that makes anti-virus software,
and Integrated Devices, that makes high-performance integrated circuits.

                               MANAGER'S OVERVIEW


     The deeper cyclical stocks, such as automotive and housing related stocks,
were disappointing this year. Though these companies had good earnings, stock
prices did not do well because of an "end of cycle halo"--a dark cloud hanging
over these stocks because investors didn't believe earnings were sustainable
this far into an extended economic cycle.

     Importantly, this year we refined our value investment process. As always,
we continue to focus on companies with attractive relative valuations, but our
process now places more emphasis on in-depth fundamental analysis. We will
require a business to have a catalyst, such as some corporate event, management
change or new product to unlock the value in the stock. And we have worked to
improve our execution and timing for buy and sell decisions.

     I believe the prospects for small-cap value is outstanding. Several
economic events have occurred to signal a positive environment for value stocks:
We have reached the peak in the market and the earnings of the economy; the rate
of growth of earnings in the economy is decelerating; and the price-to-earnings
ratio of value stocks are some of the lowest we have seen in 25 years. These
factors indicate the possibility for a very bright future for value stocks.


                                 "I BELIEVE THE
                                 PROSPECTS FOR
                               SMALL-CAP VALUE IS

   Long-Term Bond Fund



     Westcore Long-Term Bond Fund's total return for the fiscal year ended May
31, 2000, was 0.11% versus the Lehman Brothers Long-Term Government/Corporate
Bond Index of 0.65% and the Lipper Corporate Debt BBB Index of -0.41%. A bond
fund's total return equals its coupon income plus or minus changes in bond
prices. In a period of rising interest rates, bond prices typically fall.
However, the income, or yield, that a bond portfolio produces tends to rise. The
30-day SEC yield for the Fund was 6.86% as of May 31, 2000.*

     The Federal Reserve's actions to raise interest rates to slow the economy
did not have as drastic an effect on long-term rates as they did on shorter-term
rates. This was mainly due to the U.S. Treasury's announcement of a program to
buy back longer-term securities because of large budget surpluses. This action
created an increased demand for those long securities, which moderated price
declines.

     A factor that did have an effect on our performance was the dramatic
widening of credit and mortgage spreads during this time period due to potential
credit concerns, liquidity concerns in the marketplace and concerns over the
stock market.

     For this time period, we placed an emphasis on long-term treasury
securities, which have performed extremely well, and de-emphasized long-term
corporate bonds, which have had a very difficult time.

     We do, however, have a fairly large exposure to transportation securities.
Our research has found high-quality enhanced equipment trust certificates--those

securities backed by collateral, such as an airplane. Names we own in this area
are US Airways, Continental, United Airlines and Jet Equipment Trust.

     Real Estate Investment Trusts (REITs) is another corporate area that has
contributed positively to our performance. Through our research, we have
uncovered securities with solid performance opportunities due to the stable
incomes that are provided by the way the underlying companies are structured.
Two examples of companies in this area are Equity Office Properties and ERP
Operating.

     We are currently at an interesting point in the marketplace. Interest rates
are not likely to move significantly in either direction, the economy has been
too strong to warrant lower interest rates and oil price increases are
concerning from an inflationary perspective. On the other hand, the six interest
rate increases have created some slow-down in certain sectors of the economy
such as housing. These conflicting forces drive towards uncertainty, but fairly
stable interest rates. Given the expectation of continued Treasury buy-backs, we
believe long-term interest rates will remain relatively low.


IMPORTANT CHANGES TO YOUR FUND

     With this report, I believe that it is important to address a significant
upcoming change to the investment objective of the Westcore Long-Term Bond Fund.
As of October 1, 2000, the name will change to the Westcore Flexible Income
Fund. This restructured Fund will seek long-term total rate of return by
investing primarily through investments in bonds, and to a lesser extent through
convertible securities and high-yielding equities. This change will allow the
Fund to take better advantage of our fixed income team's extensive experience in
credit analysis. Additionally, the Funds' net operating expenses for the fiscal
year ending May 31, 2001 will be lower than for the fiscal year ended May 31,
2000. The Prospectus Supplement dated July 28, 2000 explains the changes in
detail.

* Without the absorption of fee waivers and/or expense reimbursements, the
30-day SEC yield would have been 6.58%.

Intermediate-Term Bond Fund

     The Westcore Intermediate-Term Bond Fund's total return for the fiscal year
ended May 31, 2000 was 1.67%. In comparison, the Lehman Brothers Intermediate
Government/Corporate Index was up 2.49% and the Lipper Intermediate Investment
Grade Debt Index returned 1.26%. A bond fund's total return equals its coupon
income plus or minus changes in bond prices. In a period of rising interest
rates, bond prices typically fall. However, the income, or yield, that a bond
portfolio produces tends to rise. The 30-day SEC yield for the Fund was 7.33% as
of May 31, 2000.*

     Total return was pushed down by the Federal Reserve raising interest rates
six times during the course of the year due to the strong economic growth and
the inflationary concerns that accompany that. Another factor contributing to
our performance was credit spreads and mortgage spreads widened dramatically
during this time period due to credit, liquidity and stock market concerns.

WESTCORE COLORADO TAX-EXEMPT FUND

FUND OBJECTIVE: Seeks to provide income exempt from both federal and Colorado
state personal income taxes by emphasizing Colorado municipal bonds with
intermediate maturities.

                                    [PHOTO]
                             /s/ THOMAS B. STEVENS
                             Thomas B. Stevens, CFA
                          Portfolio Manager, Westcore
                           Colorado Tax-Exempt Fund

   Westcore Colorado Tax-Exempt Fund's total return for the fiscal year ended
May 31, 2000 was -1.36%. In comparison, the return for the Lehman Brothers 10
Year Municipal Bond Index was -0.18%, and the Lipper Intermediate Municipal
Debt Index was -0.71%.

   Rising interest rates put pressure on the municipal market during this fiscal
year, and the total return of the Fund suffered, since bond prices move
inversely to changes in interest rates. However, as bond yields rose, investors
were offered higher tax-exempt income. The 30-day SEC yield for the Westcore
Colorado Tax-Exempt Fund was 4.82% as of May 31, 2000.* For taxpayers in a
combined Federal and Colorado income tax bracket of 34.28%, that equates to a
tax-equivalent yield of 7.33%.*

   Several factors in addition to rising interest rates have affected the
municipal bond market in Colorado this year. On the one hand, the strong
economy has caused many municipal debt ratings to improve over the past year,
which is positive for the Fund. On the other hand, because of the burgeoning
tax revenues for some of these municipalities, the need to finance public
projects has lessened. So the issuance, and consequently the supply, of
municipal debt securities has declined, making it difficult to find good
investments for the Fund.

                               MANAGER'S OVERVIEW

                                "We continue to
                              advance the idea of
                              maintaining a high-
                            quality portfolio, the
                             majority of which is
                               either insured or
                                pre-refunded to
                                   maturity."

   The Fund is focusing on bonds with higher coupons in intermediate maturities
(2-10 years) that will not be subject to wide price volatility should interest
rates continue to go up. For example, we have been purchasing some issues with
a 5.5-6.0% coupon at premiums to par value and, in the process, we've been
selling some of the deeper discount issues with coupons in the 4.25-4.5% range.
This should benefit shareholders in the Fund as most of the return will
consequently come in the form of coupon or interest income rather than price
appreciation.

   Looking ahead, it is our belief the Federal Reserve will minimize the extent
of implementing further interest rate increases. Much depends on the economic
data and inflation numbers to be released in the ensuing months. Given this, it
is our intent to gradually extend the Fund's weighted average maturity and
duration to lock in what we believe to be cyclically attractive interest rate
levels. We continue to advance the idea of maintaining a high-quality
portfolio, the majority of which is either insured or pre-refunded to maturity.
We believe this Fund continues to be a suitable investment for risk-averse
investors seeking tax-exempt income in a high-quality vehicle.

*Without the absorption of fee waivers and/or expense reimbursements, the
figures quoted would have been 4.25% for the 30-day SEC yield and 6.47% for the
tax-equivalent yield.

Lipper Index data provided by Lipper Analytical Services, Inc.

The Lehman Brothers 10-Year Municipal Bond Index is an unmanaged index that
includes investment grade (Moody's Investor Services Aaa to Baa, Standard &
Poor's Corporation AAA to BBB) tax-exempt bonds with maturities between eight
and twelve years.

Lipper Intermediate Municipal Debt Index is comprised of the 30 largest mutual

     the lesser of purchases or sales of portfolio securities (excluding
     securities with a maturity date of one year or less at the time of
     acquisition) for a period and dividing it by the monthly average of the
     market value of such securities during the period. Purchases and sales of
     investment securities (excluding short-term securities) for the period
     ended May 31, 2000 were $10,617,290 and $7,773,879, respectively.

1. SIGNIFICANT ACCOUNTING POLICIES

     Westcore Trust (the "Trust") is registered under the Investment Company Act
of 1940, as amended, as an open-ended management investment company. Interests
in the Westcore MIDCO Growth, Westcore Growth and Income, Westcore International
Frontier, Westcore Small-Cap Growth, Westcore Select, Westcore Blue Chip,
Westcore Mid-Cap Opportunity, Westcore Small-Cap Opportunity, Westcore Long-Term
Bond, Westcore Intermediate-Term Bond and Westcore Colorado Tax-Exempt Funds
("the Funds") are represented by separate classes of beneficial interest of the
Trust, which is organized as a Massachusetts business trust. The Funds, for book
and tax purposes, have a fiscal year of May 31. From October 11, 1993 to
September 30, 1995, Westcore MIDCO Growth, Westcore Growth and Income, Westcore
Small-Cap Opportunity and Westcore Intermediate-Term Bond Funds offered
Institutional and Retail classes of shares with a front-end load and their own
distribution/administrative service plan. On October 1, 1995 the Retail class
was merged into the Institutional class at the respective net asset value per
share. The distribution/administrative service plan on the Retail class was
discontinued. The front-end sales load on all the Funds was also discontinued.

     The following is a summary of significant accounting policies consistently
followed by each Fund in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles for
investment companies.

     USE OF ESTIMATES - 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. The actual results could differ from those estimates.

     INVESTMENT VALUATION - Securities of the Funds are valued as of the close
of regular trading on the New York Stock Exchange (the "NYSE"), currently 4:00
p.m. (Eastern time), on each day that the NYSE is open. Listed and unlisted
securities for which such information is regularly reported are valued at the
last sales price of the day or, in the absence of sales, at values based on the
average closing bid and asked price. Securities for which market quotations are
not readily available are valued under procedures established by the Board of
Trustees to determine fair value in good faith. Short-term securities having a
remaining maturity of 60 days or less are valued at amortized cost which
approximates market value. Foreign securities are valued at the closing price on
the principal stock exchange on which they are

                          NOTES TO FINANCIAL STATEMENTS



traded. In the event that closing prices are not available for foreign
securities, prices will be obtained from the principal stock exchange at or
prior to the close of the New York Stock Exchange. London closing quotes for
exchange rates are used to convert foreign security values into U.S. dollars.
Forward foreign currency contracts are valued based on the closing prices of the
foreign currency contract rates in the London foreign exchange markets on a
daily basis as provided by a reliable pricing vendor.

     FOREIGN SECURITIES - All of the Funds, except the Westcore Colorado
Tax-Exempt Fund, may invest at least a portion of their assets in foreign
securities. In the event that a Fund executes a foreign security transaction,
the Fund will enter into a forward foreign currency contract to settle the
foreign security transaction. Foreign securities may carry more risk than U.S.
securities, such as political, market and currency risks.

     The accounting records of the Funds are maintained in U.S. dollars. Prices
of securities denominated in foreign currencies are translated into U.S. dollars
at the closing rates of exchange. Amounts related to the purchase and sale of
foreign securities and investment income are translated at the rates of exchange
prevailing on the respective dates of such transactions.

     The effect of changes in foreign currency exchange rates on investments is
separately identified from the fluctuations arising from changes in market
values of securities held and reported with all other foreign currency gains and
losses in the Funds' Statements of Operations.

     FEDERAL INCOME TAXES - It is the Funds' policy to continue to comply with
the provisions of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of their taxable income to shareholders.
Therefore, no federal income tax provision is required. At May 31, 2000 the
Westcore Small-Cap Opportunity, Westcore Intermediate-Term Bond and Westcore
Colorado Tax-Exempt Funds had available for federal income tax purposes unused
capital loss carryovers of approximately $6,800,000, $1,100,000 and $82,000
respectively, which will expire through 2008.

     The Westcore Small-Cap Growth, Westcore Small-Cap Opportunity, Westcore
Long-Term Bond, Westcore Intermediate-Term Bond and Westcore Colorado Tax-Exempt
Funds intend to elect to defer to their fiscal year ending May 31, 2001,
approximately $609,000, $3,400,000, $1,300, $217,000 and $510,000 of losses,
respectively, recognized during the period November 1, 1999 to May 31, 2000.

<PAGE>   128

                          NOTES TO FINANCIAL STATEMENTS



     CLASSIFICATION OF DISTRIBUTIONS TO SHAREHOLDERS - Net investment income
(loss) and net realized gain (loss) may differ for financial statement and tax
purposes. The character of distributions made during the year from net
investment income or net realized gains may differ from its ultimate
characterization for federal income tax purposes. Also, due to the timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the fiscal year in which the income or realized gain was recorded by
the Funds.

     The Funds adjust the classification of distributions to shareholders to
reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended May 31, 2000, $18,273 and $30,157 for the Westcore Small-Cap Growth
and Westcore Small-Cap Opportunity Funds, respectively, have been reclassified
to paid-in-capital to reflect a post-December net investment loss which may not
be offset against capital gains or carried forward for tax purposes. In
addition, $2,178,277 and $257,867 for the Westcore MIDCO Growth and Westcore
Growth and Income Funds, respectively, have been reclassified to accumulated net
realized gain (loss) on investments to reflect an accumulated net investment
loss which was offset against short-term capital gains. The calculation of net
investment income in the Financial Highlights excludes these adjustments.

     DISTRIBUTIONS - Distributions of net investment income, if any, are made
annually for the Westcore MIDCO Growth, Westcore International Frontier,
Westcore Small-Cap Growth and Westcore Select Funds, quarterly for the Westcore
Growth and Income, Westcore Blue Chip, Westcore Mid-Cap Opportunity and Westcore
Small-Cap Opportunity Funds and monthly for the Westcore Long-Term Bond,
Westcore Intermediate-Term Bond and Westcore Colorado Tax-Exempt Funds.
Distributions of net realized gains, if any, are declared at least once each
year for each of the Funds. Distributions to shareholders are recorded on the
ex-dividend date.

     ORGANIZATION COSTS - Costs incurred in connection with the organization,
initial registration and public offering of shares have been paid by the Funds.
These costs are expensed as incurred.

     SECURITIES LENDING - The Westcore Funds may loan securities to certain
brokers who pay the Funds negotiated lenders' fees. These fees, net of
associated costs, are included in other income. The Funds receive U.S. Treasury
obligations and/or cash as collateral against the loaned securities, in an
amount at least equal to 102% of the market value of the loaned securities at
the inception of each loan. This collateral must be maintained at not less than
100% of the market value of the

                          NOTES TO FINANCIAL STATEMENTS



loaned securities during the period of the loan. The risks to the Funds of
securities lending are that the borrower may not provide additional collateral
when required or return the securities when due. As of May 31, 2000, the value
of securities loaned of the Westcore MIDCOGrowth, Westcore Growth and Income,
Westcore Blue Chip, and Westcore Long-Term Bond Funds amount to $41,556,131,
$26,350, $1,220,869 and $556,640, respectively. The value of collateral of the
Westcore MIDCO Growth, Westcore Growth and Income, Westcore Blue Chip and
Westcore Long-Term Bond Funds amounts to $42,635,584, $27,453, $1,267,301 and
$617,500, respectively.

     ALLOCATION OF INCOME, EXPENSES AND GAINS AND LOSSES - Trust expenses which
are not series specific are allocated to each series based upon its relative
proportion of net assets and/or open accounts to the Trust's totals. From
October 11, 1993 to September 30, 1995 the Westcore MIDCO Growth, Westcore
Growth and Income, Westcore Small-Cap Opportunity, and Westcore
Intermediate-Term Bond Funds allocated income, expenses (other than the class
specific expenses) and gains and losses daily to each class of shares based upon
their relative proportion of net assets represented by each class. Operating
expenses directly attributable to a specific class were charged against the
operations of that class.

     WHEN-ISSUED SECURITIES - Each Fund may purchase or sell securities on a
"when issued" or "forward commitment" basis which involves a commitment by the
Fund to purchase or sell particular securities with payment and delivery taking
place at a future date. During this period, such securities do not earn
interest, are subject to market fluctuation and may increase or decrease in
value prior to their delivery. Each Fund maintains, in a segregated account with
its custodian, assets with a market value at least equal to the amount of its
purchase commitments. The purchase of securities on a when-issued or forward
commitment basis may increase the volatility of the Fund's net asset value to
the extent each Fund makes such purchases while remaining substantially fully
invested.

     OTHER - Investment transactions are accounted for on the date the
investments are purchased or sold (trade date). Dividend income is recorded on
the ex-dividend date. Interest income, which includes amortization of premiums,
accretion of discounts and income earned on money market funds, is accrued and
recorded daily. Realized gains and losses from investment transactions and
unrealized appreciation and depreciation of investments are reported on an
identified cost basis.

4. INVESTMENT ADVISORY FEES, ADMINISTRATIVE FEES AND
   OTHER RELATED PARTY TRANSACTIONS

     The Trust has entered into an advisory agreement with Denver Investment
Advisors LLC ("DIA") for all Funds. DIA succeeded First Interstate Capital
Management, Inc. ("FICM") as investment adviser to the Westcore Long-Term Bond
and the Westcore Colorado Tax-Exempt Funds on October 1, 1995. The advisory
agreement has been approved by the Trust's Board of Trustees and shareholders
and contains terms and conditions similar to those which were in these Funds'
former advisory agreement.

     Pursuant to its advisory agreement with the Trust, DIA is entitled to an
investment advisory fee, computed daily and payable monthly of 0.65%, 0.65%,
1.20%, 1.00%, 0.65%, 0.65%, 0.75%, 1.00%, 0.45%, 0.45% and 0.50% of the average
net assets for Westcore MIDCO Growth, Westcore Growth and Income, Westcore
International Frontier, Westcore Small-Cap Growth, Westcore Select, Westcore
Blue Chip, Westcore Mid-Cap Opportunity, Westcore Small-Cap Opportunity,
Westcore Long-Term Bond, Westcore Intermediate-Term Bond and Westcore Colorado
Tax-Exempt Funds, respectively.

     Effective October 1, 1995, ALPS Mutual Fund Services, Inc. ("ALPS") and DIA
entered into an administrative agreement to serve as the Funds
co-administrators. ALPS and DIA are entitled to receive a fee from each Fund for
its administrative services computed daily and paid monthly, at the annual rate
of 0.30% of the Fund's average net assets.

     The Co-Administrators and the Investment Adviser have advised the Trust
that they currently intend to waive fees or reimburse expenses with respect to
each of the Funds so that the Total Operating Expenses of the Westcore MIDCO
Growth, Westcore Growth and Income, Westcore International Frontier, Westcore
Small-Cap Growth, Westcore Select, Westcore Blue Chip, Westcore Mid-Cap
Opportunity, Westcore Small-Cap Opportunity, Westcore Long-Term Bond, Westcore
Intermediate-Term Bond and Westcore Colorado Tax-Exempt Funds will not exceed
1.15%, 1.15%, 1.50%, 1.30%, 1.15%, 1.15%, 1.25%, 1.30%, 0.95%, 0.85%, and 0.65%,
respectively. Without such fee waivers, for the period ended May 31, 2000, the
Total Operating Expenses of the Westcore MIDCO Growth, Westcore Growth and
Income, Westcore International Frontier, Westcore Small-Cap Growth, Westcore
Select, Westcore Blue Chip, Westcore Mid-Cap Opportunity, Westcore Small-Cap
Opportunity, Westcore Long-Term Bond, Westcore Intermediate-Term Bond, and
Westcore Colorado Tax-Exempt Funds would be 1.21%, 1.73%, 2.08%, 1.72%, 1.39%,
1.28%, 3.51%, 1.67%, 1.26%, 1.11%, and 1.14%, respectively.

<PAGE>   137


                          NOTES TO FINANCIAL STATEMENTS


     Certain officers of the Funds are also officers of DIA. All affiliated and
access persons, as defined in the 1940 Act, follow strict guidelines and
policies on personal trading as outlined in the Trust's Code of Ethics.

     Expenses for the Funds include legal fees paid to Drinker Biddle & Reath
LLP. A partner of that firm is secretary of the Trust.

     The Trust has a Trustee Deferred Compensation Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of Trustees
Fees. Under the Deferral Plan, any compensation deferred results in an equal
adjustment to the Investment for/Payable for Trustee Deferred Compensation Plan
on the Statement of Assets and Liabilities, as though an equivalent amount had
been invested in shares of one or more Westcore Funds selected by the trustee.
The amount paid to the Trustees under the Deferral Plan will be determined based
upon the performance of the selected funds. Deferral of trustees' fees under the
Deferral Plan will not affect the net assets of the Fund.

     Shareholders holding more than 5% of the Funds' outstanding shares as of
May 31, 2000, constituted 13.88% of Westcore MIDCO Growth Fund, 24.19% of
Westcore Growth and Income Fund, 26.86% of Westcore International Frontier Fund,
13.24% of Westcore Small-Cap Growth Fund, 17.03% of Westcore Select Fund, 49.20%
of Westcore Blue Chip Fund, 69.66% of Westcore Mid-Cap Opportunity Fund, 49.84%
of Westcore Small-Cap Opportunity Fund, 73.36% of Westcore Long-Term Bond Fund,
58.60% of Westcore Intermediate-Term Bond Fund and 11.24% of Westcore Colorado
Tax-Exempt Fund. Included in the percentages above are holdings of DIA and/or
certain officers of DIA representing 6.52% of Westcore Growth and Income Fund,
10.75% of Westcore International Frontier Fund, 7.76% of Westcore Small-Cap
Growth Fund, 11.08% of Westcore Select Fund, 62.07% of Westcore Mid-Cap
Opportunity Fund and 5.88% of Westcore Colorado Tax-Exempt Fund.


5. ACQUISITION OF ASSETS

     On October 1, 1998, the Westcore Mid-Cap Opportunity Fund acquired all of
the assets of a separately managed investment partnership, managed by DIA, at
fair market value in a tax-free exchange for shares of the Fund, as stipulated
in the Conversion Agreement approved by the Trust's Board of Trustees. The

6. ILLIQUID OR RESTRICTED SECURITIES

     As of May 31, 2000, investments in securities included issues that are
illiquid or restricted. Restricted securities are often purchased in private
placement transactions, are not registered under the Securities Act of 1933, may
have contractual restrictions on resale, and are valued under methods approved
by the Board of Trustees as reflecting fair value. A security may also be
considered illiquid if it lacks a readily available market or if its valuation
has not changed for a certain period of time. The Funds intend to invest no more
than 15% of their net assets (determined at the time of purchase and reviewed
periodically) in illiquid or restricted securities. Certain restricted
securities, eligible for resale to qualified institutional investors, are not
subject to that limitation. The aggregate value of illiquid or restricted
securities subject to this limitation as of May 31, 2000 for the Westcore
Small-Cap Growth, Westcore Select, Westcore Long-Term Bond and Westcore
Intermediate-Term Bond Funds was $1,898,635, $562,500, $226,907 and $648,685
respectively, which represents 8.72%, 1.56%, .96% and 1.90% of the Funds' net
assets, respectively. Of the preceding amounts for the Westcore Small-Cap
Growth, Westcore Select, Westcore Long-Term Bond and Westcore Intermediate-Term
Bond Funds, $1,898,635, $562,500, $0 and $0, respectively, is considered
restricted. Information concerning restricted securities is as follows:

                          INDEPENDENT AUDITORS' REPORT


     TO THE BOARD OF TRUSTEES AND SHAREHOLDERS,
     WESTCORE TRUST:


     We have audited the accompanying statements of assets and liabilities,
including the statements of investments of the Westcore Trust (comprising,
respectively, the Westcore MIDCO Growth Fund, Westcore Growth and Income Fund,
Westcore International Frontier Fund, Westcore Small-Cap Growth Fund, Westcore
Select Fund, Westcore Blue Chip Fund, Westcore Mid-Cap Opportunity Fund,
Westcore Small-Cap Opportunity Fund, Westcore Long-Term Bond Fund, Westcore
Intermediate-Term Bond Fund, and Westcore Colorado Tax-Exempt Fund,
collectively, the "Trust") as of May 31, 2000, the related statements of
operations for the period then ended and the statements of changes in net assets
and financial highlights for each of the periods indicated. These financial
statements and financial highlights are the responsibility of the Trust's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of May 31, 2000, by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
each of the respective funds constituting the Westcore Trust as of May 31, 2000,
the results of their operations for the period then ended, and the changes in
their net assets and financial highlights for each of the periods indicated, in
conformity with accounting principles generally accepted in the United States of
America.
