DEAR FELLOW SHAREHOLDER:
    As our semi-annual report goes to press, the U.S. financial markets have
just ended another record calendar year. The S&P 500 Index has posted its fourth
year of 20% plus gains. Long-term interest rates declined nearly a full 1% for
the year as the Federal Reserve, which started the year with a bias toward
tightening interest rates, shifted to an easing mode and lowered rates three
times. Right now, the Federal Reserve has returned to a neutral stance. Numbers
do not reflect a lot of excitement that occurred during the year. As recently as
October, the S&P 500 Index was flat for the year, having declined approximately
20% from its summer peak. The Asian financial crisis had spread to South America
and Russia, hedge funds were taking huge losses and the Federal Reserve was
warning of a credit crunch in the U.S. There is no question that international
turmoil has reduced U.S. economic growth and has had a negative impact on
profits. The quick change in policy by the Federal Reserve calmed markets and
allowed the inherent strength of the U.S. economy to continue. In our view, the
U.S. economy also continues its remarkable growth because of the combination of
technology-driven productivity and real income growth for consumers. We believe
these trends should continue and over the next year we expect some of the
international news to improve.
          Bond funds provide positive returns in volatile environment.
    What does this mean for investors in the Westcore Funds? First, the good
news is that the fixed-income funds did their job in this volatile environment.
They provided a safe haven and positive returns as a result of the interest rate
decline. The Westcore Long-Term Bond Fund was ranked #1 out of 92 BBB-Rated
Corporate Bond Funds based on average annual total return for the one-year
period ended September 30, 1998 according to Lipper Analytical Services Inc.(1)
(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.) Both the Westcore
Intermediate- and Long-Term Bond Funds are significantly overweighted in
corporate bonds and we expect them to benefit as the economy grows and fears of
a credit crunch continue to dissipate. The Westcore Colorado Tax-Exempt Fund
provided a comfortable place for Colorado investors to generate double
tax-exempt income.
 
                  A stock market defined by narrow leadership.
    In spite of the excellent returns for the S&P 500 Index, equity investing
was quite challenging for the year. The advances in the stock market were very
narrow with only a handful of stocks contributing to the positive return for the
market. It was truly a year of "haves" and "have nots", with a few large-cap
growth stocks being the "haves" and most other stocks and investment styles
being the "have nots". Growth was in, value was out, big was in, small was not.

    In this environment our Westcore Blue Chip Fund and Small-Cap Opportunity
Fund, while having disappointing absolute returns, performed well versus their
peers. Westcore Small-Cap Opportunity Fund continues to receive favorable
publicity, having been included in articles suggesting funds to investors such
as the WALL STREET JOURNAL'S "Small-Stock Funds May Be Worth a Look", October
16, 1998 and KIPLINGER'S PERSONAL FINANCE MAGAZINE'S "Countdown to College",
November, 1998. Westcore MIDCO Growth and Growth and Income Funds struggled from
being in the wrong sectors and had sub-par years on the stock selection front.
Both of these funds have had excellent long-term stock selection based on
research driven investment processes, and we believe the portfolios are
positioned to see positive results from stock selection in 1999.
                      Will the stock market ever broaden?
    Yes. We believe that is an easy answer based on years of history and
experience.
    A more difficult question is when and what will be the catalyst. We are
unsure of the timing, but believe the disparity in relative valuations makes our
YES answer very probable, and believe this is an excellent opportunity in
medium-sized growth companies and value stocks across the capitalization
spectrum.
    This semi-annual report includes the first report on our newest fund, the
Westcore Mid-Cap Opportunity Fund. We hope you will consider the Fund, which
uses the same valuation and research discipline as the Westcore Blue Chip and
Small-Cap Opportunity Funds.
    Thank you for investing with us. We are dedicated to meeting your investment
objectives with our family of funds that are driven by excellent investment
research.
                         Sincerely,

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 did Westcore MIDCO Growth Fund respond to the recent market fluctuations?
A: During the first six months of our fiscal year, the market was indeed
volatile. Unfortunately, there was no way for our Fund to avoid participating in
this volatility. We were fully invested for the entire period and made some
selective additions to our holdings during periods of market weaknesses.
Q: What should our fund investors do during periods of extreme volatility in the
stock market?
A: We believe it is generally best to stay fully invested. And, if it suits your
investment objectives, add to your holding of the Fund during periods of general
market weakness. As you know, short-term volatility in the stock market has
historically turned into positive long-term returns.
Q: What are the factors you felt influenced the Fund's return over the past
couple of years?
A: Both 1997 and 1998 have been trying periods for the Fund. In 1997 our lack of
exposure to financial stocks and our overweighted holdings in healthcare
services stocks caused us to underperform our benchmark. In 1998 we have had a
much better year due to better industry weightings; specifically, lower exposure
to healthcare services. However, we are still lagging our benchmark. For the six
months ended November 30, 1998, the Fund returned -4.33% as compared to -1.55%
for the Standard & Poor's 400 Mid-Cap Index. We note two reasons for our
performance shortfall. The first reason is disappointing returns from our
holdings in the financial sector. The second is our underexposure to internet
stocks.
Q: Why should someone invest in Westcore MIDCO Growth Fund?
A: Westcore MIDCO Growth Fund is a great way to diversify your portfolio into an
asset class that offers investors the potential of higher returns than large-cap
stocks with less volatility than small-cap stocks. We are confident in our
research-intensive stock selection process and believe that we have a portfolio
made up of solid growth companies.
Q: Can you give us an example of what you consider when you make an investment
decision?
A: One of our holdings is Forest Labs, a medium-sized pharmaceutical company. We
purchased this stock when we recognized a disconnect between the company's
long-term growth potential and its stock price. Forest Labs' stock was under
pressure because investors were focused on a near-term earnings disappointment.
What we focused on was somewhat different. Our research uncovered a company with
a substantial existing product line and a strong drug development pipeline. The
drug in development with the most potential was an anti-depressant/anxiety drug
named Celexa. Celexa was to be a direct competitor with Prozac. Research

indicated that Celexa was within one year of FDA approval, and we had proof of
its success in competing for market share (Celexa was available in Europe and
had greater than 10% market share). The U.S. market for depression/anxiety drugs
is $5-6 billion. Therefore, with only a small share of the domestic market,
Forest Labs had the potential to double in size. Since our purchase of the
stock, Celexa has been approved by the FDA and fully launched in the U.S. Recent
prescription data indicate that Celexa has already accumulated 4% market share.
Since the start of the fiscal year, Forest Labs has appreciated nearly 100%.
Q: How does Westcore MIDCO Growth Fund's performance compare against its peers?
A: We have underperformed the Morningstar Mid-Cap Growth Category Average which
returned -3.03% during the last six months. However, we have outperformed it
since the inception of the Fund. (see chart below)
Q: What is your outlook for the Fund?
A: We think the outlook for the Fund is very positive. Mid-cap stock valuations
have never been more attractive relative to large caps. Further, the companies
in our portfolio have earnings that are growing faster than those companies in
our benchmark. And, finally, the economic outlook for the U.S. remains sound
with a forecast of modest GDP growth and low inflation for 1999.

                          PORTFOLIO MANAGER, WESTCORE
                             GROWTH AND INCOME FUND
Q: How did the Westcore Growth and Income Fund respond to the recent market
fluctuations?
A: The last six months have been a very volatile period. From July to October,
the Fund experienced a significant decline, but by maintaining a consistent
approach, we have now turned that around and have participated strongly in the
market recovery.
Q: What factors influenced the Fund's return in the last six months?
A: The first factor was the overall volatility of the stock market -- most of
what decreased is now increasing. In looking at industry groups, we can see that
our exposure to semiconductor stocks like Intel, Micron Technologies, Texas
Instruments, and Linear Technology, has been positive, because these stocks are
coming back strong. The reason the semiconductor industry is doing so well has
to do with a better balance in the supply and demand. The pricing environment
has been difficult, but this has finally bottomed out. Now, we are well
positioned for the upswing.
In addition, our exposure to the pharmaceutical industry has been positive.
These stocks continued to perform well even in the market downturn. However,
while we are reducing our position, we continue to maintain exposure in energy
stocks like Schlumberger and Anadarko Petroleum. These have not done well due to
the difficult oil price environment.
Q: What kind of investor might the Fund be most appropriate for?
A: We consider this Fund to be a core holding for any investor looking for
dividend income and who has a tolerance for a moderate amount of risk. The Fund
is actually designed to have characteristics similar to the S&P 500 Index in
terms of risk and dividend yield, and strives to outperform this index through
good stock selection.
Q: Can you explain how some of your current holdings meet your investment
strategy?
A: Many of our investors will recognize these examples from our portfolio.
General Electric is one of our holdings -- it is a quality company with a 1.2%
dividend yield. This yield is very close to that which you would find in the S&P
500 Index. We expect good earnings growth in this company which has about the
same risk as the market. Another stock in our portfolio with a 1.3% dividend
yield is Colgate Palmolive.
Pfizer would be an additional example. We believe this high quality
pharmaceutical company has some exciting new products. Plus, existing products
are experiencing strong growth.
Q: When looking at the Fund's performance against its index and peers, why
didn't the Fund's return match theirs?
A: For the six months ended November 30, 1998, the Fund had a total return of
- -5.60%, lagging both the S&P 500 Index of 7.48% and the Morningstar Large Blend
Category Average of 3.39%. When looking at the Fund's performance, it is
important to note that we blend large- and mid-cap stocks for our holdings.
While large caps provide safety and a good dividend yield, mid-caps provide
growth attributes. Unfortunately this year's market was extremely selective with
a few large companies fairing well, but mid-caps lagging behind. And, since our
focus has always been to include mid-caps stocks with the Fund, this has created
some lower returns.

Q: Did sector weightings change in the Fund? Why and how did it affect the Fund?
A: We did make some changes in the Fund by reducing our energy exposure and
increasing technology holdings. We felt that the energy sector was weakening
when we watched oil prices drop and worldwide demand soften. However, we also
believed that the near-term concerns with technology stocks were exaggerated and
fully reflected in the stock prices, so we decided it was an opportunity to
increase our holdings in this area.
Q: What were some of the major economic issues that impacted the Fund this past
year?
A: With the economic deterioration of both Japan and Russia, there was some
significant impact to many of our large consumer stocks that have products
exported overseas. For example, Gillette had developed a new razor and expected
attractive sales in Russia. However with Russia's faltering economy, Gillette's
original sales estimate was lowered substantially.
Q: There has been a lot of speculation on whether we are headed for a recession
in the U.S. Where do you think the economy is going for the new year?
A: We believe the economy will continue to grow and inflation will remain low.
These two factors should combine to support a favorable investment environment
in 1999.

                          PORTFOLIO MANAGER, WESTCORE
                                 BLUE CHIP FUND
Q: How did the Westcore Blue Chip Fund respond to the recent market
fluctuations?
A: The Fund moderately lagged the S&P 500 Index in the recent market
fluctuations. The third quarter was a difficult period for all investors due to
global economic and financial uncertainty. The uncertainty caused investors to
rapidly change their outlook, resulting in unusual market instability. In
addition, pricey shares of growth-oriented companies continued to perform well.
The disciplined investment approach and diversified portfolio held by the Fund
allowed it to weather this market instability without undue risk.
Q: What factors influenced the Fund's return?
A: The impact of good stock selection and diversification in the Fund helped it
perform defensively in a difficult market environment. Good stock selection
resulted in the Fund holding some strong performers while the market generally
weakened through the 3rd calendar quarter of 1998. During this period, we
reduced our exposure to certain financials and capitalized on the market
volatility by acquiring several solid technology companies at depressed prices.
These actions worked to limit risk and position the Fund for participation in
the market's rebound.
Q: What kind of investor might the Westcore Blue Chip Fund be most appropriate
for?
A: We consider Westcore Blue Chip Fund to be a core holding for investors
looking for attractive returns and who prefer to own stocks of well-known, large
companies purchased at relatively inexpensive prices. The Fund typically holds
shares of companies that are global leaders in their industries, and historical
research suggests that these types of large, value stocks have the lowest level
of risk of any equity asset class. In addition, many people enjoy finding
quality goods at value prices when spending their own money. The Westcore Blue
Chip Fund is a comfortable match for these investors.
Q: How does the Fund's performance compare to its index and peers?
A: For the six months ended November 30, 1998, the Fund had a total return of
- -3.61% lagging both the S&P 500 Index and the Morningstar Large Value Category
Average which returned 7.48% and -0.81%, respectively.
Q: How do some of your current holdings in Westcore Blue Chip Fund meet your
investment strategy?
A: Tellabs Inc. is a successful telecommunications equipment company. Recently,
a merger deal that was expected to conclude failed to close. Investors were
surprised and the price of the stock declined substantially, even though the
company's profits were strong and continued to rise. Our research indicated that
the future was still bright for Tellabs and we acquired the stock at a
much-reduced price. The shares have subsequently recovered and continue to
perform very well for the Fund.
Rite Aid, a popular drug store chain, has been a long-term holding for the Fund.
We selected the stock originally because our quantitative research indicated
that the stock was cheap. Our qualitative research suggested that the company's
business was fundamentally sound. Rite Aid has produced stable growth resulting
in consistent, good stock returns. Since our initial purchases in 1995, the
stock price has increased more than four fold. This is the type of stock we will
continue to hold until our analysis uncovers unfavorable conditions or better
values elsewhere.

Q: What were some of the major economic issues that impacted the Fund this past
year?
A: As most everyone is well aware, during the past 6 months, investors' global
optimism has shifted to a view that the world economy is weakening. In addition
to financial stocks, this shift impacted cyclical and manufacturing stocks, and
created a difficult investing environment. Initially, the overwhelming
conclusion seemed to be that the domestic economy would also turn negative and
result in reduced consumer spending. Many manufacturing, consumer products, and
leisure-related stocks declined significantly. While these declines hurt some of
the Fund's holdings, they also resulted in some excellent opportunities for the
Fund to buy strong businesses whose stocks had suffered in sympathy with their
weaker counterparts. Throughout this time, we have continued to utilize our
investment approach to improve the quality of the Fund's holdings for the
future.
Q: Can you explain what sector didn't do as well as you expected this past year
and why?
A: Financials and cyclical stocks were hardest hit during the recent market
adjustments. With low interest rates, we would normally expect to see strong
performance from financials. However, financials were impacted negatively due to
major concerns over international currency relationships, the overall
instability of various countries' economies, and the dramatic shifts in interest
rates for various types of loans. These international developments caused many
financial stocks to decline. Asia's slow down and concerns that this would
spread to other economies called into question the future outlook for
manufacturing companies with exports going into foreign markets. It also brought
concerns of a recession in the U.S. that could reduce spending on goods and
services. These developments caused significant adjustments in the values of
manufacturing and cyclical stocks.
Q: Have you implemented any changes in the Fund's investing strategies?
A: While maintaining a focus on owning large value companies, in June we
broadened our stock selection universe to more closely reflect the stocks in the
S&P 500 Index, including stocks that don't pay dividends. The impact on the Fund
has been very favorable because it allowed us to buy more technology stocks at
attractive prices during the market correction. Since July 30, 1998, we
purchased shares in five technology companies that have produced strong
performance, with increases averaging 23% for the Fund through the date of this
writing.

                            MID-CAP OPPORTUNITY FUND
Q: How did Westcore Mid-Cap Opportunity Fund respond to the recent market
fluctuations?
A: We consistently applied our value-based investment approach in which we look
for the cheapest investment opportunities across a variety of market
environments. The recent market activity provided some opportunities to add to
technology holdings where the stocks were attractively priced relative to cash
flow, book value and the outlook for improving earnings and business
fundamentals. The Fund also benefited from a recovery in transportation stocks,
as interest rate cuts by the Federal Reserve helped alleviate some of the
uncertainty about the economy. Also, lower jet fuel prices and cost cutting
improved the outlook for transportation stocks.
Q: What factors influenced the Fund's return?
A: Westcore Mid-Cap Opportunity Fund's October inception date proved timely. The
Fund's return was most heavily influenced by the rising equity market driven by
a rebound from the summer lows and the Federal Reserve's interest rate cuts.
Q: What kind of investor might the Fund be most appropriate for?
A: Westcore Mid-Cap Opportunity Fund will appeal to those long-term investors
who want to invest in the mid-cap asset class with a value approach. We believe
mid-caps offer better earnings growth over time than larger-cap stocks, but with
less volatility than smaller-cap stocks. Our value style invests in companies
with attractive prices that also have stable or improving businesses.
Q: Describe how some of your current holdings meet your investment strategy.
A: Kmart Corporation displays many of the characteristics we look for in an
investment for Westcore Mid-Cap Opportunity Fund. This stock has an attractive
valuation relative to book value and cash flow, and the business fundamentals
are improving. Kmart is a turnaround story. The company, as well as other
discount mass merchandisers, is benefiting from bargain hunting domestic
consumers. An improved store format has helped sales for Kmart Corporation and
as a result, earnings have turned back up.
Q: Would you please explain your research methods for picking stocks and how you
incorporate a value approach?
A: We use a research process that combines quantitative analysis with the
qualitative judgement of the investment management team. Our discipline focuses
on finding opportunities in stocks that have attractive valuations based on a
seven-factor model that includes cash flow, book value and year-over-year
earnings growth. Then the portfolio management team looks for improving trends
in sales, margins, products and other fundamental business characteristics, a
favorable competitive outlook and a management team that can execute a
reasonable business plan.

                                         Semi-Annual Report November 30, 1998
 
Q: How do you define the mid-cap universe? What benchmark do you measure
against?
A: The Mid-Cap universe includes companies with market capitalization (stock
price times shares outstanding), that fall within the combined market cap range
of the Russell Mid-Cap Index and the S&P Mid-Cap Index. This generally results
in a universe of companies with market caps from just under $1 billion through
companies just over $10 billion dollars. Our performance is benchmarked against
the Russell Mid-Cap Index.
Q: How does your new fund fit in with the overall family?
A: We believe that the Fund completes Westcore's value fund line-up. With its
inception we have closed the gap between our Westcore Small-Cap Opportunity and
Westcore Blue Chip Funds--now providing value investors with the full spectrum
of value stocks. The research processes and value approach of the two
pre-existing Funds is applied to the mid-cap asset class, which offers investors
exposure to companies that are larger and perhaps more established than
small-cap stocks, and while more volatile, generally are expected to have higher
long-term earnings growth than large-cap stocks.

                           SMALL-CAP OPPORTUNITY FUND
Q: How did the Fund respond to the recent market fluctuations?
A: The Fund performed as we would expect from a solid, small-cap value fund. The
Fund outperformed when the market declined during the third quarter and
participated in the subsequent upside.
Q: What factors influenced the Fund's return?
A: For the six months ended November 30, 1998, the Fund's return of -15.31%
lagged the Russell 2000 Index of -12.35% and the Morningstar Small Value
Category of -15.09%. The last six months presented a challenging environment for
owners of small-cap stocks. Investors favored larger stocks with growth-oriented
characteristics. However, good stock selection and a diversified portfolio
enabled the Fund to perform in line with its peers during this challenging
period.
Q: What kind of investor might Westcore Small-Cap Opportunity Fund be most
appropriate for?
A: We believe the Westcore Small-Cap Opportunity Fund is a strong core holding
for investors seeking small stock exposure while limiting risk in his or her
overall asset allocation plan, through the Fund's value approach to investing.
The investor needs to understand the added risk involved with smaller stocks.
However, history suggests that a long-term investment in Westcore Small-Cap
Opportunity Fund may take advantage of the potential of this asset class to
outperform both the large- and mid-cap sectors, and to dampen the risk
associated with small stocks through its value approach.
Q: How do some of Westcore Small-Cap Opportunity Fund's current holdings meet
its investment strategy?
A: Ben and Jerry's Homemade, the well-known maker of premium ice cream, has been
an excellent holding for the Fund. Our research process suggested in October
1997 that the stock was undervalued. Our qualitative research indicated that new
management was implementing changes to improve plant efficiencies as well as
successfully lining up new distribution agreements. We have seen the company
generate strong sales growth and good profit improvement, making this a
successful holding for the Fund.
Personnel Group of America is a stock that we purchased during the recent market
volatility. The company is a personnel staffing services provider that had
focused on clerical help, but more recently had grown significantly in the area
of providing information technology (IT) personnel. When the economy appeared to
be slowing, some investors began selling this stock, along with the stocks of
other staffing service providers. Investors reasoned that the corporations who
purchased these services would want to reduce costs and discontinue their use of
temporary employees. As a result the stock price of Personnel Group of America
dropped and our valuation model suggested that it would be an attractive buy for
the Fund. Our qualitative research suggested that because of the company's
increased involvement in IT personnel and outsourcing, the demand for their
"temporary" services would be more resilient than their peers, even if the
economy did slow. Since our purchase, the profitability of Personnel Group has
remained strong and the stock has increased nicely in value.
Q: When looking at the Fund's performance against its peers, how did it compare?
A: Westcore Small-Cap Opportunity Fund has significantly outperformed its peer
group over the last 3- and 5-year periods, and performed in line with its peers
over the last year.
Q: What are your research methods for picking stocks and how do you incorporate
a value approach?
A: We focus on owning bargain priced stocks of companies with solid and
improving business fundamentals. We utilize a computer model and analysis to

identify companies with attractive stock prices and positive trends in their
business. We then look at qualitative matters (management changes, industry
developments, economic and stock market trends, etc.) to determine the near-term
prospects for the stock. This disciplined process has enabled us to capitalize
on some of the recent stock market developments to the benefit of our
shareholders.
Q: What were some of the top performing stocks in the Fund recently?
A: Neomagic Corporation, the developer of a leading edge chip for graphics in
notebook computers, has been a strong performer for the Fund. The company
supplies approximately 40% of the market for its product, and its customer list
includes 16 of the largest notebook PC makers. When the Asian economy weakened,
technology stocks in general declined rather dramatically. At that time, the
price of Neomagic's stock declined to a new historic low. The market's
indiscriminate reaction to the Asian trouble allowed us to purchase this stock
at a very inexpensive price. Earnings for the company haven't faltered and the
stock has returned to a significantly higher price level since our purchase.
Ames Department Stores is a discount department store chain in the northeast
United States. The stock price was negatively impacted, along with retailers in
general, by the broad-brush fear that the retailing sector would suffer due to
growing economic uncertainties. Our valuation models indicated that that stock
price of Ames was cheap, and our qualitative work found that Ames was
progressing well in implementing changes to improve profitability by closing
some of its poorer performing stores. We determined that Ames would be a good
holding and the stock has performed very well since our purchase.
 
Q: What is the outlook for the Westcore Small-Cap Opportunity Fund?
A: We are very optimistic about the Fund and the opportunities available for the
upcoming year. Since September 1998, three interest rate cuts have already been
implemented, and such cuts have historically resulted in small stocks
outperforming other asset classes. In addition, small value stocks remain very
inexpensive relative to larger stocks. Over the last year, the Fund has
attracted increased attention due to its strong performance history and our use
of a consistent investment process. We have continued to see a steady inflow of
new investments into the Fund.

                              LONG-TERM BOND FUND
Q: How did Westcore Long-Term Bond Fund respond to the recent market
fluctuations?
A: Recent market fluctuations reinforced our long-term strategy. The
fluctuations in interest rates produced volatility in price, but our Fund
maintained a long duration as a means to provide holders the benefit of declines
in interest rates. The Fund continued to focus on investment-grade U.S.-based
securities. This focus kept us out of the worst of the most recent market
concerns involving emerging markets. Due to the increase in the spread between
the yields of treasury securities and other fixed income securities we purchased
more corporate securities. Underlying companies remained strong providing
opportunities to enhance expected returns given these wider spreads.
Q: What factors influenced the Fund's return?
A: Three reductions in short-term interest rates by the Federal Reserve since
this past September spurred a strong bond market that benefited the Fund. When
interest rates fell, long-term securities appreciated in price significantly.
While strong, performance results were dampened by the increased difference
between corporate security yields and treasury security yields due to increased
supply and reduced demand spurred primarily by economic concerns related to
foreign market crisis conditions.
Q: What kind of investor might the Fund be most appropriate for?
A: This fund is appropriate for an investor who wants a portfolio generally less
volatile or with more diversification than an all equity portfolio. Investors
should have a reasonably long investment horizon given the long-term nature of
the securities in the portfolio. From a market outlook perspective, investors
will do best in the fund when inflation is declining and economic strength is
moderate.

                                         Semi-Annual Report November 30, 1998
 
Q: When looking at the Fund's performance against its index and peers, how did
it compare?
A: For the six months ended November 30, 1998, the Fund returned 6.33% which
lagged the Lehman Brothers Long-Term Government/Corporate Bond Index return of
7.76%. However, the Fund outperformed the Morningstar Long-Term Bond Category
Average of 3.13%. This Fund maintains a long-term structure, which is generally
longer than its peers. When interest rates decline, longer securities increase
in price more than shorter securities. Also, our emphasis on domestic investment
grade issues kept us away from some areas that caused significant problems in
the portfolios of some of our peers.
Q: Where do you see the bond market headed?
A: We believe that the widening of spreads to levels generally associated with
severe economic turmoil provides opportunities for outperformance. Our weighting
in corporate and asset-backed securities was increased to take advantage of this
market opportunity. Our focus on solid fundamental analysis puts us in a good
position to provide value in this turbulent environment.

                          INTERMEDIATE-TERM BOND FUND
Q: How did Westcore Intermediate-Term Bond Fund respond to the recent market
fluctuations?
A: Recent market fluctuations have reinforced our management style for the Fund.
The intermediate maturity of the Fund's securities provides very little price
volatility in comparison with many other bond fund types. Our focus on
investment-grade U.S.-based securities also dampened the volatility experienced
in the emerging market and high-yield categories of fixed income. There was an
increase in the spread between the yields on treasury securities and other
fixed-income securities as the market moved, creating opportunities in
asset-backed and corporate securities. We increased our holdings in these areas
to structure the portfolio in keeping with the higher yields available.
Q: What factors influenced the Fund's return?
A: The Federal Reserve reduced short-term interest rates three times since
September of 1998. This lowered all rates and contributed to solid performance
by the Fund. Intermediate-term securities do not move in price as much as
long-term securities and our heavy weighting in corporate bonds diminished
performance as spreads widened. Increased supply and reduced demand spurred by
concerns over the crisis conditions existing in many foreign markets contributed
to this general widening of spreads.
Q: What kind of investor might the Fund be most appropriate for?
A: This fund may be ideal for investors who want a more stable component in
their diversification mix. This stability is appropriate for more conservative
investors and those with a short investment time horizon. Return of principal is
a higher reward for investors in this fund than the return on their principal.
Q: When looking at the Fund's performance against its index and peers, how did
it compare?
A: For the six months ended November 30, 1998, the Fund's total return was 3.42%
versus both the Lehman Brothers Intermediate Government/Corporate Index and the
Morningstar Intermediate-Term Bond Category average returns of 5.04% and 3.99%,
respectively. In comparison to the index and our peers, the Fund is more
conservatively structured and did lag both over the last few months, primarily
due to the shorter duration in a declining interest rate environment. Returns
were very consistent with the style, but lagged somewhat due to our heavy
emphasis on corporate bonds.

                                         Semi-Annual Report November 30, 1998
 
Q: Why did corporate bonds suffer over the last 6 months?
A: The bond market can best be characterized as a market where the best returns
were in the longest-term high-quality issues. Corporate bonds suffered due to a
tremendous supply pressure made worse by a fear of an economic slowdown. The
economic slowdown fears were driven by the foreign crisis environment and
reduced stock prices in the third quarter. Spreads between government and
corporate securities were driven wider to try and bring demand back in line with
supply. The fear environment was one that treated government securities very
well. This in turn caused mortgage-backed securities to experience a very
difficult period as refinancing activity accompanied the lower interest rates.
Q: So what was the direct impact on the Westcore Intermediate-Term Bond Fund?
A: The shorter securities did not fare as well as longer securities, but still
showed solid results. The performance was dampened by the underperformance of
corporate securities, but none of the major market problems associated with
emerging markets and high yield were experienced in our Fund.

FUND STRATEGY: SEEKS
TO PROVIDE INCOME EXEMPT FROM BOTH FEDERAL AND COLORADO STATE PERSONAL INCOME

                          PORTFOLIO MANAGER, WESTCORE
                            COLORADO TAX-EXEMPT FUND
Q: How did the Westcore Colorado Tax-Exempt Fund respond to the recent market
fluctuations?
A: The past six months have been positive for the Fund. When market prices
decline and yields rise, people want to place their investment dollars into
safer investment vehicles. During these periods our Fund, consisting
predominantly of higher quality, insured municipal bonds, becomes increasingly
attractive to investors. Our net asset value stabilizes, resisting price
erosion.
Q: What factors influenced the Fund's return?
A: Much of what positively impacted the Fund has to do with the volatility in
the market. The Asian and Russian crises caused some investor fear and
uncertainty, initiating a "flight to quality." Plus, the yield spread
differential between U.S. Treasuries and tax-free bonds remains attractive, as
is evident in the municipal yield being 90%-95% of Treasury bond yields.
Q: What kind of investor might the Fund be the most appropriate for?
A: This Fund would be best suited for the conservative investor who is looking
for a double tax-exempt fund with no loads or 12b-1 fees consisting
predominantly of higher quality, insured municipal bonds. We work to make sure
that the Fund is highly diversified geographically within Colorado. Ultimately,
this Fund is for people who want a return of their money as well as on their
money.
Q: When looking at the Fund's performance against its peers, how did it compare?
A: We outperformed our peer group. From June through November of 1998, Westcore
Colorado Tax-Exempt Fund's total return was 3.73% and the Municipal Single State
Intermediate Category's total return was 3.15% as of 11/30/98 according to
Morningstar. We work to control bond maturity risk and volatility by holding
intermediate maturity bonds. In addition, the Fund tends to perform extremely
well in a market downturn.
Q: Did any sector weightings change in the Fund? Why and how does it affect the
Fund?
A: There has been an increase in educational districts in the Fund's portfolio.
Currently 48% of the holdings are Colorado School bonds. Education is not only a
major priority of the Federal government, but of the State government as well.
Since a 1994 Colorado statute, the Colorado Intercept Program, was passed, the
State's treasurer and Department of Education have worked together to ensure
that the payment of principal and the interest on school district bonds is met
when due. The State treasurer will actually make payment for the district if
they are unable to pay on time. Then the treasurer will withhold funds from the
district's future state assistance until the loan is repaid through the
treasurer's withholding funds. With the added support of the state behind each
bond, Moody's Investors Service and Standard & Poor's Ratings Group have
assigned their ratings of Aa3/AA- for all school districts that participate in
this state sponsored program. This program definitely gives us an incentive to
own these bonds.

Q: Would you explain your research methods for picking bonds?
A: It is fair to say that we won't buy anything with high debt ratios. One of
the critical parts of our research process involves employing credit quality
guidelines to get a accurate read of a bond. Just because a bond is insured
doesn't mean we will buy it. We look beyond insurance to the ultimate credit.
Then, besides gathering the numerical data and information on the bond, we also
like to visit the districts to make sure we have a complete assessment and
understanding of each holding.

(1) A portfolio turnover rate is, in general, the percentage computed by taking
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 November 30, 1998 were

    STATEMENTS                       REPORT                       (UNAUDITED)
 
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 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.
 
    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.
 
    DISTRIBUTIONS - Distributions of net investment income, if any, are
distributed annually for the Westcore MIDCO Growth Fund, 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 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 November 30, 1998, the value of securities loaned of the Westcore MIDCO
Growth, Westcore Blue Chip and Westcore Small-Cap Opportunity Funds amount to
$27,969,063, $648,656 and $2,279,188, respectively. The value of collateral of
the Westcore MIDCO Growth, Westcore Blue Chip and Westcore Small-Cap Opportunity
Funds amount to $29,134,774, $684,500, and $2,695,397, 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,
 
                                                                              53

    STATEMENTS                       REPORT                       (UNAUDITED)
 
1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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.
 
    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 November 30, 1998, there was an unlimited number of no par value shares

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
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%,
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 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 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 Growth and Income, 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%, 1.15%, 1.25%, 1.30%, 0.95%, 0.85%, and 0.65%, respectively.
Without such fee waivers, for the period ended November 30, 1998, the Total
Operating Expenses of the Westcore MIDCO Growth, Westcore Growth and Income,
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 1.14%, 1.91%, 1.24%, 11.16%, 1.56%,
1.20%, .99% and 1.09%, respectively.
 
    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.
 
                                                                              57

  TRANSACTIONS (CONTINUED)
    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. The deferred fees are invested in certain Westcore Funds until
distribution in accordance with the Deferral Plan.
 
    Shareholders holding more than 5% of the Funds' outstanding shares as of
November 30, 1998, constituted 33.65% of Westcore MIDCO Growth Fund, 39.59% of
Westcore Growth and Income Fund, 62.01% of Westcore Blue Chip Fund, 61.97% of
Westcore Mid-Cap Opportunity Fund, 58.43% of Westcore Small-Cap Opportunity
Fund, 66.43% of Westcore Long-Term Bond Fund, 73.39% of Westcore
Intermediate-Term Bond Fund, and 47.60% of Westcore Colorado Tax-Exempt Fund.

of a separately managed investment partnership, managed by DIA, at fair market
value in exchange for shares of the Fund, as stipulated in the Conversion
