DEAR FELLOW SHAREHOLDER:
    Another year, another record! Both the U.S. economy and the U.S. financial
markets continue to add to the length and magnitude of their amazing results.
Since our last annual report the Dow Jones Industrial Average has gone up
through the 7000, 8000, and, most recently, 9000 levels. Interest rates for this
period, as measured by long-term treasury bonds, have declined approximately a
full percent from 7% to 6%. The U.S. economy continues to produce above-average
growth with low inflation. A year ago we were talking about the deficit
approaching its lowest level relative to Gross Domestic Product in 15 years and
now the discussion has shifted to budget surpluses. All of this good news has
occurred in the face of an economic and financial meltdown in most of Asia.
    Will the record setting environment continue? The clear answer, of course,
is no, but there are no signs on the horizon that suggest a near-term change.
Low inflation and low interest rates plus low unemployment create strong
real-income growth and, combined with the demographically-driven shift to more
savings and investments and the technologically-driven improvement in
productivity, the ingredients remain in place for this favorable environment to
continue for the foreseeable future.
    Nonetheless, record high valuations make the market vulnerable to external
shocks, and simple arithmetic suggests that from these levels the returns on
stocks and bonds are unlikely to continue at the rates of the last few years.
The value of investment research in identifying attractive individual securities
and structuring portfolios has never been more important.
                     Better Research Makes the Difference.
    Investment research is an ongoing process and the key to investment
performance. At Westcore we offer a variety of funds intended to meet individual
investment objectives.
    Thus, at any given time, our research team may be:
 
    - meeting with company management to assess growth opportunities,
 
    - poring over complex Securities and Exchange Commission documents and
      financial statements to assess credit-worthiness to discover corporate
      credits that are due for upgrades, or
 
    - building sophisticated quantitative models that help us identify stocks
      with the value characteristics that historically have led to good
      performance.
    Research is a combination of discovery and learning. We are always trying to
discover the best investment ideas and to learn from market history as well as
from our successes and failures.
    The performance of our research-driven approach has resulted in favorable
publicity for our funds during the year.

    - Westcore Long-Term Bond Fund ranked #3 out of 101 BBB-Rated Bond Funds
      based on total return for the year ended March 31, 1998 according to
      Lipper Analytical Services, Inc.(2) (Total return represents past
      performance. Past performance is not indicative of future results. Without
      the absorption of fee waivers and expense reimbursements, total return
      figures would have been lower.)
                                   Year 2000
    The "Year 2000 Issue" arises because most business/financial software
written over the past 20 years uses only two digits to specify the date, rather
than four. Therefore, on January 1, 2000, unless software is repaired, computers
with date-sensitive software programs will recognize the year as "00" and may
treat the year as 1900. This could result in computer failure and/or lead to
incorrect calculations.
    Westcore Funds has established a Year 2000 Project Team, which is taking
steps that it believes are reasonably designed to address the Year 2000 Issue.
Westcore utilizes major service providers in the operations of the Funds'
business, including the investment adviser, administrator, transfer agent and
custodian. While there can be no guarantee these service providers' systems will
be converted on a timely basis, steps are being taken with each of the Funds'
service providers to evaluate their efforts to address their own Year 2000
situations. At this time, Westcore expects an orderly transition into the 21st
Century.
              New Portfolio Manager and New and Improved Services
    During the year Jerry Powers took over as portfolio manager for Westcore
Long-Term Bond and Intermediate-Term Bond Funds. Jerry is an experienced
portfolio manager with a research background and a history of managing
fixed-income portfolios substantially larger than the current Funds. His
background is ideally suited to continuing the investment record and style of
these two funds.
    Several new services have been introduced. Westcore Funds has made it easy
for shareholders to take advantage of changes in tax laws that enhanced the
flexibility and tax advantages of IRAs and the new Roth IRAs. We have also added
new services to make investing with us easier. Effective August 5, 1998,
information on fund prices, yields and performance as well as specific account
information, including calendar year-end balances, current account balances and
recent transactions will be available 24 hours through the new Westcore
Automated Service Line. Purchases, redemptions and exchanges can also be done 24
hours-a-day using Westcore's Automated Service Line or our online Westcore
Trans@ction Center.
                             Introducing a New Fund
    I am proud to announce that Westcore is launching a new fund that will be
available for investment October 1, 1998. The Fund will seek to maximize
long-term capital appreciation by investing primarily in medium-sized companies
whose stocks appear to be undervalued. Look for more information in your October
prospectus mailing.
    Thank you for investing with us for the long-term, and if you are a new
Westcore shareholder -- welcome! We are dedicated to continue meeting your
investment objectives through our commitment to investment research.
                         Sincerely,
                         [JACK D. HENDERSON SIGNATURE]

(1) In the WALL STREET JOURNAL article titled "Your Starting Point for Mutual
Funds? Here Are 65 of Them in the Annual List", the author started with all
5,174 stock-mutual funds. A series of computer screens using a software program
offered by Morningstar Inc. called Morningstar Principia Plus were run. A list
of 65 was comprised by excluding the following: funds that charge a sales
commission; funds with annual expenses greater than 1.4% or an investment
minimum above $5,000; single industry sector or single foreign region funds;
global funds that buy both U.S. and foreign stocks; funds with fund-manager
tenure averages below five years; and funds that failed to outperform 60% of
comparable funds over the past three and five years.
(2) Westcore Long-Term Bond Fund ranked 11th out of 35 funds for the 5-year
period ended 3/31/98. Average annual total returns reflect the reinvestment of
dividends, capital gains distributions, all fee waivers and expense
reimbursements. Investment return and principal value will vary, and shares,
when redeemed, may be worth more or less than their original cost. Westcore fund

     Manager's Overview
 
Westcore MIDCO Growth Fund
FUND OBJECTIVE: SEEKS TO MAXIMIZE LONG-TERM CAPITAL APPRECIATION BY INVESTING
PRIMARILY IN MEDIUM-SIZED GROWTH COMPANIES.
                          [TODGER ANDERSON, CFA PHOTO]

                              TODGER ANDERSON, CFA
                 PORTFOLIO MANAGER, WESTCORE MIDCO GROWTH FUND
Q: How was Westcore MIDCO Growth Fund's performance this year?
A: The total return for Westcore MIDCO Growth Fund's fiscal year was 15.10% --
in absolute terms, a very satisfying number. However, on a relative basis when
this number is compared to the S&P 400 Mid-Cap Index, our results were
disappointing. The return on that index was 29.90% for the period.
Q: Why didn't the Fund's return match those of the indices?
A: There are two primary reasons. First, we were underweighted in financial
stocks. We believed these stocks were fully valued relative to their growth
rates. In fact, they went to new historically high valuations. Second, we were
overweighted in healthcare service stocks and these stocks had a tough year.
Q: Didn't some healthcare stocks do well this year?
A: Yes, the very large drug companies such as Pfizer and Merck. Westcore MIDCO
Growth Fund focuses on medium-sized growth companies, and the healthcare service
stocks in our portfolio did not participate in the advances of drug stocks.
Q: What industry was your best?
A: Specialty Retailing was our best. Our investments in this industry included
companies such as Dollar General, Lowe's, TJX Cos., Kohls and Pier One Imports.
Q: Why did Specialty Retailing do so well?
A: Lower interest rates and energy prices left consumers with more money for
discretionary spending. And, because consumers felt confident about their jobs
they spent a lot on such things as clothing and household items.
Q: Can you give us some background on one of the companies you find particularly
interesting?
A: Dollar General is a discount retailer that has developed a successful
business strategy to meet the needs of a segment of the population for everyday
products that are priced affordably. In addition, the management of this company
has re-merchandised its retail locations to emphasize high-margin, high-turnover
products. For example, you might find ironing board covers in one of these
stores, but you wouldn't find ironing boards because they take longer to move
off the shelves.

Q: What other stocks did well this year?
A: Two stocks that performed well were America Online and WorldCom. More and
more people are connecting to the Internet, and they frequently do this using
America Online. The stock began the year at $28 and ended the year at $83.
WorldCom is our largest holding. It began the year at $30 and ended the year at
$46. Its business is strong and its merger with MCI looks like it will be
successful.
Q: What is your outlook for next year?
A: I believe the stock market will continue to move up but perhaps not as much
as it has over each of the last few years. Stock prices will probably move up in
line with earnings growth, but I do not expect price/earnings ratios to expand.
Q: Why should someone invest -- or stay invested -- in Westcore MIDCO Growth
Fund?
A: Mid-cap stocks may be an attractive sector over the long-term because I
believe they have the potential to outperform large-cap stocks, with less
volatility than small-caps. This fund can be owned by anyone with a time horizon
of three to five years or longer. My two-year old grandson is a MIDCO
shareholder, and so am I at age 54 (it's my largest personal holding). As
always, it depends on your time-horizon, your tolerance for volatility and your
own, individual investment objectives.

                          PORTFOLIO MANAGER, WESTCORE
                                 BLUE CHIP FUND
Q: How did the Westcore Blue Chip Fund perform relative to its benchmark?
A: The Fund's total return was 29.53%, while the S&P 500 Index was 30.69% for
the year ended May 29, 1998. Large growth stocks that trade at higher valuations
outperformed large value stocks, which is the emphasis of this Fund.
Nevertheless, the Fund outperformed a large value index, the S&P/Barra Value,
which consists of the value stocks within the index.
Q: Did you make any sector weighting changes? Why and how did it affect the
Fund?
A: We reduced Consumer Staples from a slightly overweighted position to match
the index more closely. We increased the Credit Sensitive sector from an
underweighted position to a modest overweighting, which contributed to the
performance of the Fund.
Q: Did you make any investment strategy changes?
A: Late in the fiscal year, we broadened our universe of permissible investments
to include the largest 500 of the Russell 1000 Index as well as all stocks in
the S&P 500 Index. This change increased our investment options while still
maintaining the emphasis on blue chip stocks. It also allowed us to include
stocks that do not pay dividends. We believe that this change is likely to
benefit shareholders and is more comparable to the benchmark, the S&P 500 Index.
Q: How is your investment strategy working?
A: The Fund's strategy is working well against its large-cap value peers while
matching or slightly lagging the S&P 500 Index. It is working well relative to
peers because we focus on owning undervalued stocks with improving businesses
rather than owning "deep discount" stocks that may be very cheap but have
deteriorating businesses or stock prices that may stay flat for an extended
period of time.
Q: How did the economy affect the performance of the Fund?
A: Low interest rates have produced rising profitability for financial stocks
and soaring stock prices. As financials typically have lower valuations, they
have been a strong contributor to the performance of the Fund. The economic and
financial trouble in Asia halted what appeared to be the building of a nice
advance for basic industry stocks.
Q: Do you have any stories about how your research process added value to the
Fund?
A: Unisys, a mainframe computer company, was a stock our quantitative work
identified as having an attractive valuation and a business that was beginning
to turn around after many years of slowing revenues and declining earnings. We
purchased the stock when the company's earnings were exceeding Wall Street's
expectations, and our analysis showed business was improving. It is an example
of our quantitative research combined with experienced judgment identifying a
stock at the right time, and the stock has nearly doubled in price since we
acquired it in September 1997.

                                                   Annual Report May 29, 1998
 
Q: What is the outlook for the Fund?
A: The outlook for the Fund seems favorable at this time. Volatility that
financial markets may experience due to the unfolding Asian situation suggests
that stock picking may become increasingly important. So long as interest rates
are low and U.S. consumers and market participants remain optimistic, investing
in U.S. stocks should continue to produce attractive returns.
Q: What kind of investor is the Fund right for?
A: I like to think of the Westcore Blue Chip Fund as a "core holding" in the
equity portion of an investor's portfolio. Investors who are new to investing in
equities may benefit from a value strategy and may appreciate the recognizable
names in the Westcore Blue Chip Fund.

Westcore Small-Cap Opportunity Fund
FUND OBJECTIVE: SEEKS TO MAXIMIZE LONG-TERM CAPITAL APPRECIATION PRIMARILY
THROUGH INVESTMENTS IN DOMESTIC AND FOREIGN EQUITY SECURITIES OF
SMALL-CAPITALIZATION COMPANIES.

                           SMALL-CAP OPPORTUNITY FUND
Q: Westcore Small-Cap Opportunity Fund had a good year relative to its
benchmark, the Russell 2000 Index. To what do you attribute this good
performance?
A: Yes, the Fund returned 30.40% compared to 21.24% for the Russell 2000 Index.
We had strong stock selection in several areas -- foods, consumer cyclicals,
services, financials, energy and transportation.
Q: Did sector weightings change in the Fund?
A: Generally, our investment philosophy is to keep economic sector weights in
the Fund similar to those in the Russell 2000 Index. However, we did increase
our weighting in the financial area somewhat, which enhanced the return of the
Fund. We also added high yielding REITs (Real Estate Investment Trusts).
Q: How did the economy affect the performance of the Fund?
A: A strong economy produced rising profits, which benefited many of our
businesses.
Q: Can you share an example of how your investment processes added value this
year?
A: Timberland is a company that makes brown leather casual shoes. This product
is in favor in the marketplace, while the popularity of expensive athletic shoes
is declining. When well-known athletic shoe makers announced earnings
disappointments, Timberland stock declined in sympathy with the overall
industry. Our quantitative analysis identified the stock as attractively priced.
We purchased the stock and the market relatively quickly corrected the error,
producing a positive return for the Fund. Our proprietary valuation models are
designed to identify a pricing opportunity such as this before the market
corrects it.
Q: What other stocks performed well?
A: When Cato Corporation's namesake, John Cato, returned to lead this women's
apparel retailer, he improved merchandising of apparel and sales began to
improve and earnings to pick up. We discovered the stock early and it is now up
over 100% since the Fund acquired it in July 1997. Another stock that was priced
low and identified early was Varlen Corporation whose truck manufacturing
business is exceeding everyone's expectations. Varlen Corp. is up over 85% since
we added it to the portfolio in July 1997.

Q: Why is the value approach to investing working for this Fund?
A: It makes intuitive sense and it is backed by research that demonstrates when
you buy mispriced stocks -- inexpensive stocks with improving businesses -- good
things can happen.
Q: What type of investor might the Westcore Small-Cap Opportunity Fund be right
for?
A: We believe that the small-cap sector of the market has the potential to
perform better on average than large- and mid-cap sectors over time and that the
value approach may reduce volatility. Investors with a long-term investment
horizon who desire diversification into small-cap stocks may find this Fund
particularly interesting.

TOTAL RETURN BY INVESTING IN EQUITY SECURITIES SELECTED FOR THEIR GROWTH
POTENTIAL AND INCOME PRODUCING ABILITIES.

                             GROWTH AND INCOME FUND
Q: How did the Westcore Growth and Income Fund perform against its benchmark,
the S&P 500 Index?
A: The Westcore Growth and Income Fund had a total return of 20.74% for the
year. This was lower than the 30.69% of the S&P 500 Index -- mainly because
large-capitalization stocks continue to dominate the advances in the market.
This year the market rewarded the predictability of earnings and liquidity that
large companies offered.
    We believe that large-cap stocks may be overvalued, and the earnings growth
rates of smaller companies will be stronger than larger companies in the next
year. Therefore, we have recently begun to reduce the market-cap size of our
holdings. A movement to smaller stocks in the coming year may be inspired if
large company earnings were to disappoint investors due to factors such as
exposure to foreign markets. The companies we are invested in have strong
earnings growth rates that should compare favorably to the average U.S. company
in the year ahead.
Q: Did you make any sector weighting changes? Why and how did it affect the
Fund?
A: Yes, early in the fiscal year we increased our holdings in Drug stocks -- a
move that benefited the portfolio. Significant new products were introduced by
companies like Pfizer and Warner Lambert and we invested at the right time to
participate in the positive effect this had on their stock prices.
    We also raised our energy sector holdings at the beginning of the year
because we expected an increase in energy usage in this healthy economy. A
warmer than normal winter this year, due to the El Nino effect, and the Asian
slowdown reduced the demand for energy. As a result this group didn't perform as
well as expected. However, our underlying evaluation of this sector remains
unchanged and we expect improvement in the coming year.
Q: How did the economy affect the performance of the Fund?
A: The strong consumer environment of the last year had a very positive impact
on our retail stocks such as Dollar General and Family Dollar. A strong housing
market, low interest rates, and healthy consumer balance sheets buoyed building
materials stores such as Home Depot and Lowe's. Lower interest rates also had a
positive impact on our financial stocks.

                                                   Annual Report May 29, 1998
 
Q: What is the outlook for the Fund and market?
A: We feel positive about the near-term, because it appears that inflation will
stay low and the economy will continue to grow. A positive interest rate
environment, an accommodative Federal Reserve, and a healthy consumer
environment, among other things, indicate a healthy economy overall, and stocks
in general are expected to do well. We believe our holdings are undervalued and
will deliver strong earnings growth.
Q: What kind of an investor is the Westcore Growth and Income Fund right for?
A: An investor looking for dividend income and a moderate amount of risk. Also,
an investor concerned about capital gains taxation from year-to-year, since we
try to minimize the tax effects of buy and sell decisions in the Fund. Overall,
we like to think the Westcore Growth and Income Fund is designed for the "middle
of the road" investor -- not too conservative and not too aggressive.

                          INTERMEDIATE-TERM BOND FUND
Q: Tell us about the Fund's performance.
A: The Westcore Intermediate-Term Bond Fund had a total return of 8.88% for the
year ended May 29, 1998. This was slightly higher than the 8.84% return for the
Fund's benchmark, the Lehman Brothers Intermediate-Term Government/Corporate
Bond Index.
Q: Why did the Fund outpace its benchmark?
A: Our large exposure to the corporate sector of the bond market enhanced our
performance, because intermediate-term corporate bonds provided more yield than
was available in government securities. The decline in interest rates enhanced
the total return and modestly enhanced the return relative to the benchmark
since we generally maintained a slightly longer-maturity portfolio.
Q: How did the economy affect your performance?
A: The robust economic growth strengthened the already strong fundamental
position of many of our corporate holdings. At the same time, the low inflation
numbers allowed intermediate-term interest rates to continue to drop.
Q: Why do you have such a significant emphasis on corporate bonds?
A: The emphasis on corporate bonds originates from the belief that their higher
yields generate sufficiently higher returns to offset their higher risk. As in
all Westcore Funds, research is critical. Opportunities to add value through
research are abundant in corporate bonds where the underlying credit
fundamentals will determine the return over an economic cycle.
Q: What does the near-term economic environment look like?
A: The economy is beginning to show some signs of slower growth, but remains in
extremely strong condition. Unemployment is at very low levels, and wage
increases are trending modestly higher. Fears of weakness in our domestic
economy due to the serious economic problems being suffered in Asia limit any
desire by the Federal Reserve to increase interest rates.

                              LONG-TERM BOND FUND
Q: How did the Fund perform against its benchmark?
A: The Westcore Long-Term Bond Fund had a total return of 16.63% for the year
ended May 29, 1998. This was lower relative to the 18.24% return on the Fund's
benchmark, the Lehman Brothers Long-Term Government/Corporate Bond Index. On an
absolute return basis, however, this was a very strong return.
Q: What factors influenced the Fund's return?
A: Total return was helped by the decline in interest rates created by a very
strong economy. Our performance was less than the index since the maturity of
the Fund was slightly shorter than the benchmark. Our heavy emphasis on
corporate bonds in the long-term portfolio weakened our performance in
comparison to the benchmark. This was due to the market's anticipation that
Asian economic problems would cause weakness in U.S. companies. Longer maturity
corporate bonds underperformed government bonds in this period. Despite this
recent weakness, we remain committed to our emphasis on corporate bonds. We
believe the opportunity to use our experience and exceptional research skills in
the corporate sector can add value to the Fund over the long-term.
Q: What economic environment were you working in?
A: The low inflation numbers drove long-term interest rates lower in spite of a
stable Federal Reserve policy. Market participants for years have been expecting
an increase in inflation, but it has failed to materialize in spite of a very
robust economy with tremendous job growth. This strong economy can, in part, be
credited to productivity improvements companies have achieved by capital
investments.

Q: What type of investor would the Westcore Long-Term Bond Fund be right for?
A: This Fund has a higher degree of volatility than one might expect from a
fixed-income fund, due to the longer maturity. This makes it a potentially
attractive fund for investors who believe interest rates will move lower due to
inflation remaining low, the reduction in government debt issuance and the
general demand for financial assets. It can also be a diversifying asset for
those concerned they have an overexposure to the equity market. The greater
volatility may be appropriate for investors with a long-term investment horizon
who can withstand shorter-term fluctuation in the Fund's net asset value.

     Manager's Overview
 
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.    [ROBERT O. LINDIG PHOTO]
                          [ROBERT O. LINDIG SIGNATURE]
                                ROBERT O. LINDIG
                          PORTFOLIO MANAGER, WESTCORE
                            COLORADO TAX-EXEMPT FUND
Q: How did the Westcore Colorado Tax-Exempt Fund perform this year?
A: During the year ended May 29, 1998, the Fund had a total return of 7.32%
compared to the Lehman Brothers 10-Year Municipal Bond Index total return of
9.28%. Based on the high quality and insured bond emphasis of the Fund, this
shortfall is not unexpected in the current interest rate environment. The Lehman
Brothers 10-Year Municipal Bond Index measures a national universe of municipal
issues as opposed to a single-state fund. In addition, the quality ratings
within the Index are lower than those of the Fund. These factors contributed to
the shortfall.
Q: Can you explain how you approach management of the Fund?
A: The goal of Westcore Colorado Tax-Exempt Fund is to seek federal and Colorado
state tax-exempt income consistent with safety and stability of principal. This
objective results in the selection of high-quality and insured bonds with a
taxable equivalent yield differential that is attractive in comparison to U.S.
Treasury issues with similar maturities. By emphasizing intermediate-term
maturities, the Fund reduces the interest rate risk volatility normally present
in a long-term fund. Additionally, the Fund maintains a low portfolio turnover
ratio to minimize the tax effect of capital gains and losses.
Q: Although total return is not your primary goal, are you taking any steps to
improve the tax-exempt yield and income in the current market environment?
A: Yes, the Fund has started to add higher coupon bonds with longer maturities
(10-15 years) and intermediate (5-8 years) call features. This type of bond is
intended to increase current tax-exempt income as well as yield to maturity --
because if they are not called for payment on the call date, we obtain a longer
stream of income and a higher yield to maturity. In addition, to augment current
income levels the Fund is concentrating on purchasing "full coupon" premium
bonds that are non-callable.
Q: The assets of the Fund have tripled over the last three years. To what do you
attribute this growth and how has it affected your management of the Fund?
A: We believe Colorado investors have discovered a high-quality, double
tax-exempt fund with no loads, no 12b-1 fees and a low expense ratio as compared
to other Colorado tax-exempt bond funds. The growth has not changed our
management of the Fund -- we continue to add high quality issues to the
portfolio. Insured and escrowed bonds collectively represented 84% of the Fund
portfolio as of May 29, 1998, whereas Aaa/AAA issues represented only 53% of the
Lehman Brothers 10-Year Municipal Bond Index. We diversify the types of
municipal projects we invest in, such as school districts, fire protection
districts, general obligation hospitals, sales and use tax revenue and
water/sewer and sanitation systems. In addition, we geographically divide the
holdings, and on May 29, 1998 the Fund held over 120 different Colorado issues.
Our geographic exposure mirrors the population concentration of the state:

                                                   Annual Report May 29, 1998
 
Q: What was the market environment like for investment-grade bonds this year?
A: During the Fund's fiscal year, the demand for investment-grade municipal
securities was relatively balanced against the available bond supply. The 20 GO
Bond Buyer Index, a standard for evaluating overall municipal market trends,
declined to 5.13% on May 29, 1998 from 5.63% on May 28, 1997.
Q: To what type of investor would this Fund be attractive?
A: First and foremost the Fund seeks to offer double tax-exempt income to
Colorado residents -- so they do not pay federal or Colorado state income tax on
the income generated by the Fund. It seeks to provide double tax-exempt income
while striving for safety and stability of principal through its emphasis on
intermediate maturities and high-quality, insured issues. As of May 29, 1998,
the average maturity of the Fund's portfolio was 9.34 years. As such, it may be
a desirable fund for a core portion of the portfolio for more conservative or
tax conscious, income-seeking Colorado investors.

    STATEMENTS                       REPORT                      MAY 29, 1998
 
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 Blue Chip, Westcore Small-Cap
Opportunity, Westcore Growth and Income, Westcore Intermediate-Term Bond,
Westcore Long-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 Small-Cap Opportunity, Westcore Growth and
Income 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 at 4:00 p.m.
(Eastern time) on each trading day. 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.
 
    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 29, 1998 the
Westcore Intermediate-Term Bond and Westcore Colorado Tax-Exempt Funds had
available for federal income tax purposes unused capital loss carryovers of
$1,741,936 and $22,532, respectively, which will expire through 2006. During the
year ended May 29, 1998, $48,444 of capital loss carryovers were utilized by the
Westcore Intermediate-Term Bond.
 
    During the year ended May 29, 1998 the Westcore MIDCO Growth Fund and
Westcore Growth and Income Fund had redemption-in-kind transactions in the
amount of $50,625,860 and $4,678,687, respectively, based on the fair value of
the individual securities within the portfolio. These transactions resulted in
gains of $16,287,524 and $1,655,090, which will be recognized as a permanent
difference for tax purposes.
 
    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 29, 1998, amounts have been reclassified to reflect an
accumulated net investment loss which may not be offset against capital gains or
carried forward for tax purposes. In Westcore MIDCO Growth Fund net investment
losses of $10,781,704 and realized gains relating to redemption-in-kind
transactions of $19,196,536 have been reclassed to Paid-in Capital. In Westcore
Growth and Income Fund realized gains relating to redemption-in-kind
transactions of $1,655,090 have been reclassed to Paid-in Capital.
 
                                                                              49

    STATEMENTS                       REPORT                      MAY 29, 1998
 
1. SIGNIFICANT ACCOUNTING POLICIES (Continued)
    Distributions - Distributions of net investment income are distributed
annually for the Westcore MIDCO Growth Fund, quarterly for the Westcore Blue
Chip, Westcore Small-Cap Opportunity and Westcore Growth and Income Funds and
monthly for the Westcore Intermediate-Term Bond, Westcore Long-Term Bond and
Westcore Colorado Tax-Exempt Funds. Distributions of net realized gains, if any,
are declared at least once each year. 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 being amortized over the period of benefit, but not to exceed
sixty (60) months, from the Funds' commencement of operations.
 
    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 loaned securities during the period of the loan.
As of May 29, 1998, the value of securities loaned of the Westcore MIDCO Growth,
Westcore Small-Cap Opportunity and Westcore Growth and Income Funds amount to
$97,547,494, $1,905,800 and $172,219, respectively. The value of collateral of
the Westcore MIDCO Growth, Westcore Small-Cap Opportunity and Westcore Growth
and Income Funds amount to $105,326,062, $1,938,930 and $181,751, respectively.
 
    Allocation of Income, Expenses and Gains and Losses - Trust expenses, which
are not series specific, are allocated to each series based upon their relative
proportion of net assets and/or open accounts represented by each series. From
October 11, 1993 to September 30, 1995 the Westcore MIDCO Growth, Westcore
Small-Cap Opportunity, Westcore Growth and Income 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.
 
    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
and accretion of discounts, 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 which is the same basis
the Funds use for federal income tax purposes.
 
2. CAPITAL SHARE TRANSACTIONS
    On May 29, 1998, there was an unlimited number of no par value shares of

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 advisor to the Westcore Long-Term Bond
and the Westcore Colorado Tax-Exempt Funds on October 1, 1995. The advisory
agreements have been approved by the Trust's Board of Trustees and shareholders
and contain 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%,
1.00%, 0.65%, 0.45%, 0.45% and 0.50% of the average net assets for Westcore
MIDCO Growth, Westcore Blue Chip, Westcore Small-Cap Opportunity, Westcore
Growth and Income, Westcore Intermediate-Term Bond, Westcore Long-Term Bond and
Westcore Colorado Tax-Exempt Funds, respectively.
 
    Effective October 1, 1995, ALPS and DIA entered into an administration
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 Funds' 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 Blue Chip, Westcore Small-Cap Opportunity, Westcore Growth and Income,
Westcore Intermediate-Term Bond, Westcore Long-Term Bond and Westcore Colorado
Tax-Exempt Funds will not exceed 1.15%, 1.15%, 1.30%, 1.15%, 0.85%, 0.95% and

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 MIDCO Growth Fund, Westcore Blue Chip Fund,
Westcore Small-Cap Opportunity Fund, Westcore Growth and
Income Fund, Westcore Intermediate-Term Bond Fund, Westcore
Long-Term Bond Fund and Westcore Colorado Tax-Exempt Fund as
of May 29, 1998, the related statements of operations for the
year 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 generally
accepted auditing standards. 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 also
includes examining on a test basis, evidence supporting the
amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned at May
29, 1998, 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, such financial statements and financial
highlights present fairly, in all material respects, the
financial position of the Westcore MIDCO Growth Fund,
Westcore Blue Chip Fund, Westcore Small-Cap Opportunity Fund,
Westcore Growth and Income Fund, Westcore Intermediate-Term
Bond Fund, Westcore Long-Term Bond Fund and Westcore Colorado
Tax-Exempt Fund of the Westcore Trust as of May 29, 1998, and
the results of their operations, the changes in their net
assets and financial highlights for each of the periods
indicated in conformity with generally accepted accounting
principles.
