DEAR SHAREHOLDER:

[PICTURE APPEARS HERE]

We are pleased to provide your WM Group of Funds' annual report for the period
ended June 30, 1998. The tradition at WM Group of Funds began in 1939 with the
creation of the BOND & STOCK FUND, one of the first 50 mutual funds in the
country. For nearly 60 years the organization has built a reputation in the
mutual fund industry for performance, integrity and commitment to client
services. Today, we manage approximately $5 billion in assets and serve almost
210,000 shareholder accounts.

The equity market continued to set record highs during the past 12 months, with
the Dow Jones Industrial Average breaking through the 9000 mark. As share prices
have risen on Wall Street, so has investors' interest in -- and reliance on --
stocks and stock mutual funds as the building blocks for retirement portfolios
and other investment strategies.

If you've been invested in equity funds during the last several years, you've
likely noticed some impressive gains in your portfolio. During the three years
ended June 30, 1998, the stock market posted an average annual return of over
30%, as measured by Standard & Poor's Composite Index (S&P 500). This is far
above the longer-term average of 11% a year--so it may be time to review your
investment strategy and your overall portfolio allocation.*

As part of a diversified portfolio, stocks play an important role in long-term
investing. Historically, they have offered investors the opportunity to earn
returns significantly higher than the rate of inflation. Yet you should be
careful about being overly optimistic in your expectations, and also remember
that ups and downs are a normal part of the market cycle.

Because market turbulence is part of investing in equities, I encourage you to
look at the returns of any investment relative to its potential volatility.
Although stocks have historically provided higher average annual returns than
other investment classes, they also carry greater risk of volatility. One way to
help reduce volatility in your portfolio while still pursuing opportunities for
growth is to allocate your investments among several appropriate asset classes.
For example, during the 20-year period ended June 30, 1998 stocks returned
17.42% annually on average, compared with 10.94% for long-term bonds. Allocating
70% of a portfolio to stocks and 30% to bonds during that period would have
resulted in a slightly lower average annual return of 15.69% per year, but with
a 20% reduction in volatility relative to an all-stock portfolio.*

The same theory also holds true for investors who seek income. Allocating a
small percentage of the portfolio to stocks can actually help reduce overall
volatility. That's because bond prices often react differently to changes in the
economy than do stocks.  This is also true on a global perspective, where
economies and markets are less correlated and a portion of assets invested
internationally can lower overall portfolio risk, in addition to providing the
potential for higher returns.

With the complexities of today's global markets, building an appropriately
diversified portfolio is increasingly difficult. WM Group of Funds offers
investors a broad range of professionally-managed diversification solutions,
including our family of 18 mutual funds (9 of which are presented in this
report) and 5 STRATEGIC ASSET MANAGEMENT PORTFOLIOS, which use active asset
allocation designed to meet specific investment objectives and help investors
manage risk.

Together with the WM STRATEGIC ASSET MANAGER, A TAX-DEFERRED VARIABLE ANNUITY,
the WM Funds offer you a diversity of asset classes and investment vehicles
through which you can pursue your financial goals. We suggest meeting with your
Investment Representative to discuss your overall investment strategy. Thank you
for your continued confidence in us.

Sincerely,



William G. Papesh
President

THE YEAR IN REVIEW AND OUR OUTLOOK FOR 1998-1999

STRONG FUNDAMENTALS CONTINUE TO DRIVE FINANCIAL MARKETS

The bull market continued its strength during the 12 months ended June 30, 1998,
with stocks rising over 30%. Among the strongest performers were large-cap
growth stocks, while mid-caps followed, and small-caps rounded out domestic
equity results.

Underlying this strength are sound fundamentals in the economic picture. A low-
inflation environment is generally good for financial markets, and inflation has
been very benign. That, in turn, has helped keep interest rates in check despite
a growing economy.

Interest rates dropped throughout the period. The yield on the benchmark 30-year
Treasury bond hovered around 6% for much of the period, hitting a record low in
June.

CONSUMERS SPUR GROWTH

Paradoxically, personal incomes have risen even though companies' labor costs
have shown only small increases. Real (after inflation) personal income rose
2.9% in 1997 and is expected to rise about 3.9% in 1998. One way that companies
have managed to control costs without sacrificing wage increases is through more
efficient use of technology. U.S. businesses have continued to post significant
gains in productivity, helping them remain cost competitive even in a tight
labor market.

Note: The Dow Jones Industrial Average is an unmanaged index of 30 stocks and is
sometimes used to measure the overall U.S. equity market. Individuals cannot
invest directly in an index.

The increase in personal incomes has contributed to a boost in consumer
spending, helping to sustain economic growth in the 3% to 4% range. During the
first quarter of 1998, gross domestic product (GDP) rose at an annual rate of
5.5%, largely driven by consumer rather than business or government spending.
Although GDP growth slowed in the second quarter, prospects for the second half
of 1998 are strong.

Government spending has actually been declining, which is another bright spot
for the economy. The current fiscal year, ending September 30, is likely to see
a budget surplus for the first time in nearly 30 years. 

POTENTIAL TROUBLE SPOTS FOLLOW WEAKNESS IN ASIA

Nevertheless, there are several possible spots in the economy which could have a
negative impact on the markets, and which investors will want to watch closely.

One factor is that short-term interest rates remain unusually high when compared
with inflation. The Federal Reserve, which influences short-term rates, has
maintained a steady policy during the last year even as inflation has fallen. As
a result, rates on three-month Treasuries have remained at about 5%, while
inflation is only 1.7% (as measured by CPI).

In administering interest-rate policy, members of the Federal Reserve Board's
("Fed") Open Market Committee look to potential future inflation -- so the
current stance may indicate that they believe the strength of the economy could
trigger higher inflation in coming months. In a recent address, Fed Chairman
Alan Greenspan indicated that they may have to notch interest rates upward given
the prospects for growth in the second half of 1998.

Another area of potential concern is the rising trade deficit, due largely to a
slowdown in exports to Asian markets. Remember Asia's bout of severe market
volatility and the financial crisis it sparked late last year? Many newly-
industrialized Asian markets remain in turmoil while Japan, the second-largest
export market for the U.S., remains in an economic slump.

The impact of the Asian crisis on American companies, particularly those in the
technology sector, is more favorable for companies that import goods from Asia
than those who export there. Dell Computer, for example, reported that lower-
cost Asian components have allowed them to reduce prices and spur sales. Digital
Equipment, on the other hand, said that it lost substantial business when Asian
orders were canceled as

a result of the sharp slowdown in economic activity there. Overall, the degree
of impact of the Asian crisis on the domestic economy and corporate profits
remains unclear.

THE YEAR 2000 PROBLEM

At the stroke of midnight on New Year's Eve, 1999, some computer systems could
become seriously confused. They may miscalculate critical data, delete vital
files, or simply not turn on, all because the computer's internal calendars and
clocks may not recognize the year 2000.

This computer system problem, that has come to be popularly known as the Year
2000 Problem, The Millennium Bug -- or simply Y2K -- grows out of the habit of
abbreviating years to their last two digits. Now, many systems may not be able
to decide correctly when a year 00 should be interpreted as 1900, and when it
should be seen as 2000.

Aside from being an enormous inconvenience, the Y2K problem could have
significant market repercussions for individual stocks as well as the overall
markets. Services of companies which have already prepared for the millennium,
or which have capabilities to assist other companies in preventing future
problems, are in line to receive the lion's share of government and corporate
capital spending on technology. The Clinton Administration has budgeted $3.9
billion in fiscal 1999 to upgrade the federal government's computers. Worldwide,
a survey by Giga Information Group estimated that companies will spend $300
billion to fix systems with Y2k problems.

INTERNATIONAL INVESTMENTS POST GAINS

On the international front, many investors in developed international markets
saw significant gains over the last 12 months. Stocks in Europe outpaced the
gains seen in the high-flying domestic markets. Countries in Asia and the
Pacific region showed very poor overall results throughout the past year. As a
whole, measured by the Morgan Stanley Capital International World Index, global
equities advanced over 17%. This was concentrated in the more developed
countries as emerging international markets were down for the year.

Looking ahead, the outlook for international investment remains favorable. The
Organization for Economic Cooperation and Development predicts that Western
Europe's GDP will match that of the United States' for 1998, forecast at 2.7%
growth. A major longer-term factor is the planned introduction of a single
currency -- the Euro -- in 1999. As of June 1998, 11 European countries have
indicated they will adopt the Euro as their common currency.

A DIVERSITY OF OPPORTUNITIES

Today's economic and market environment offers diverse opportunities in domestic
stock and fixed-income investments as well as investments in foreign markets.
This was clearly evident during the period as the economic crisis in Asia caused
investors to pour money out of investments and currencies of the region. In
addition, a close look at domestic markets uncovers a huge disparity in results
relative to market capitalization. Over the period, large-cap stocks appreciated
twice as much as small-caps. Volatility has increased in all markets, and the
need for professional, active money

management is greater than ever. Because of these factors, we at the WM Group of
Funds, stress diversification and the benefits provided by asset allocation.

Different markets and asset classes respond differently to ever-changing
economic factors. When one market is up, another may be down. Therefore,
investing in a properly-allocated portfolio will help to avoid some of the risks
of a single asset class.

Diversification works to manage risk. The example below demonstrates the
positive tradeoff between risk and reward achieved through diversification. Over
the past 20 years, THE DIVERSIFIED PORTFOLIO GENERATED NEARLY 80% OF THE RETURN
WITH MORE THAN 40% LESS RISK. This concept is especially important in today's
marketplace. Many of your portfolios will have a larger concentration in stocks
than you originally planned. The rebalancing of assets is another way to reduce
your portfolio's risk exposure.

general oversight responsibility for the advisory services provided to the
Funds. These services include formulating the Funds' investment policies,
analyzing economic trends that affect the Funds, and directing and evaluating
the investment services provided by the Sub-Advisors and the individual
Portfolio Managers of each Fund. WM Advisors supervises the Portfolio Managers
in their day-to-day management of the Funds in the WM Group of Funds family to

UNDERSTANDING THE ENCLOSED CHARTS AND PERFORMANCE FIGURES

In order to help you understand the WM Funds' investment performance, we have
included the following discussions along with graphs that compare the Funds'
performance with certain market indices. Descriptions of these indices are
provided next to the individual graphs on the following pages.

Generally, an index represents the market value of an unmanaged group of
securities, regarded by investors as representative of a particular market. An
index does not reflect any asset-based charges for investment management or
other expenses. Total return is used to measure a Fund's performance and
reflects both changes in the price of the Fund's shares as well as any income
dividend and/or capital gain distributions made by the Fund during the period.
Past performance is not a guarantee of future results.

A mutual fund's share price and investment return will vary with market
conditions, and the principal value of an investment when you sell your shares
may be more or less than the original cost.

The 30-day SEC yield is computed by dividing net investment income per share
over the one-month period ended June 30, 1998, by the maximum offering price on
that date, and annualizing the result.

Yield indicates the investment income per share as a percentage of the offering
price, whereas total return includes both net investment income and changes in
the value of the shares as a percentage of the initial investment. The 30-day
SEC yield is the yield calculated pursuant to a standard formula required by the
Securities and Exchange Commission ("SEC") for performance advertisement
purposes, and does not imply any endorsement or recommendation by the SEC.

ECONOMIC CONDITIONS WHICH AFFECTED THE FUND PERFORMANCE

The Asian economic crisis, which commenced at the beginning of 1997 and reached
its peak in mid to late 1997, resulted in a "flight to quality" and a strong
rally in the U.S. bond market as Treasury bond yields declined. Economic data
released during the 12 months ended June 30, 1998, continued to indicate
strength in the U.S. economy. However, the pace of growth was moderate in some
regions due to a slowdown in manufacturing and export activity. Consumer
confidence remained high as income and spending continued to increase. Also,
housing demand was up due to relatively low interest rates. However, the labor
market remained tight, and the unemployment rate declined to a 28-year low of
4.3% during April and May of 1998.

The State of California also experienced economic growth during the period,
albeit at a slower pace. Housing sales and construction activity during the
period were both strong. However, manufactur-ing activity was tempered by a
reduction in exports to Asia.

All yield information represents past performance, which cannot guarantee future
results. Principal is not guaranteed or insured by the U.S. Government, and
yields will fluctuate depending on market conditions. There is no assurance that
the portfolios will maintain the $1.00 per share net asset value ("NAV").

Due to a lack of inflationary pressures, the Federal Reserve left its target Fed
funds rate (the rate at which banks borrow from one another) unchanged at 5.50%
during its May and June 1998 meetings. The benchmark 90-day U.S. Treasury bill
yield declined from 5.48% in December 1997, to 4.98% on June 1, 1998, and then
rose to 5.08% on June 30, 1998. Average tax-free daily money market yields also
declined from 3.55%, in January 1998, to 1.75% in February 1998, and then rose
to 4% on June 30, 1998.

ECONOMIC AND INTEREST RATE OUTLOOK

We expect inflation to remain tame and anticipate a gradual slowdown in the U.S
economy as exports to Asia continue to decline and domestic price levels
decrease due to cheaper imports from Asia. We also expect the slowdown in the
economy to reduce the risk of inflation, resulting in a continued decline in
interest rates. Conversely, there is still a risk of pressures on both prices
and rates, if the effect of the Asian economic crisis is not as strong as
projected. Nevertheless, we do not anticipate a Fed rate action in the near
future.

Despite the growth in revenues resulting from California's economic expansion,
the State government continues to be plagued by a General Fund deficit that
accumulated during the early 1990s. In addition, the fiscal flexibility of the
State and its municipa-ities are hampered by various ballot initiatives.
Nevertheless, we continue to view the State's outlook as stable.

PORTFOLIO STRATEGY

Effective March 23, 1998, WM Advisors, Inc. assumed management of the California
Money Fund. The WM California Money Fund's net assets at June 30, 1998, totaled
$37.47 million. As part of our overall strategy, we reduced the Fund's exposure
to securities subject to the alternative minimum tax. We also extended the
Fund's weighted average maturity to reduce its exposure to the more volatile
daily variable rate securities.

PORTFOLIO'S PERFORMANCE

As of June 30, 1998, the seven-day simple yield for Class A shares of the WM
California Money Fund was 2.51%, or 2.54% on a compounded annual basis. The Fund
had a weighted average maturity of 52 days* as of June 30, 1998.

TARGET MATURITY 2002 FUND

PORTFOLIO MANAGER:
GARY POKRZYWINSKI
WM ADVISORS, INC.

The day-to-day management of the Target Maturity 2002 Fund's portfolio is the
responsibility of a fixed-income team headed by Senior Portfolio Manager Gary
Pokrzywinski, who has over 12 years of asset management experience and has been
with WM Advisors, Inc. for more than 5 years. Mr. Pokrzywinski is a Chartered
Financial Analyst and holds a Business Degree from the University of Wisconsin.
Mr. Pokrzywinski began managing the Target Maturity 2002 Fund on March 23, 1998.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE LAST SIX MONTHS?

The Fund's investment objective is to hold 90% of its assets in zero-coupon
Treasury Notes with a November 2002 maturity. Therefore, its net asset value
(NAV) has increased due to the net decrease in Treasury rates during the entire
period. The yield on the 30-year U.S. Treasury Bond hit an all-time low on June
15, 1998. The price of the Fund is sensitive to interest rate changes, so as
rates have dropped, the Fund has performed well.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS THAT HAVE HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

Consistent with the Fund's investment objective, the Fund has consistently held
90% of its assets in November 2002 zero-coupon Treasury STRIPs. As of March
1998, WM Advisors, Inc. took over management of the Fund with no significant
changes in management style.

WHAT IS OUR INTERMEDIATE AND LONG-TERM OUTLOOK FOR THE FUND?

Given the objective of the Fund to remain invested in Treasury STRIPs maturing
at its termination date, the Fund's NAV will move inversely to interest rates.

Over time, as its termination date approaches, the duration of the Fund will
shorten, lessening the impact of changes in interest rates on the NAV.

When the termination date is reached, the November 2002 Treasury STRIP will
mature.

WHAT IS OUR OVERALL ECONOMIC OUTLOOK FOR THE NEXT 12 MONTHS?

Over the next 12 months we expect the economy to exhibit moderate growth. The
effects of the fallout in Asia should help keep growth and inflation under
control. Global price competition and the higher levels of imports into the
United States should support this scenario. Overall, there continues to be
worldwide structural forces at work (fiscal austerity, demographics, excess
capacity) which should keep inflation under control for the next 3 to 5 years.
Unexpected economic impacts stemming from Asia and Russia remain wildcards for
overall global growth.

SHORT TERM HIGH QUALITY BOND FUND

PORTFOLIO MANAGER:
GARY POKRZYWINSKI
WM ADVISORS, INC.

The Short Term High Quality Bond Fund is managed by a fixed-income team led by
Senior Portfolio Manager Gary Pokrzywinski, who has over 12 years of asset
management experience and has been with WM Advisors, Inc. for more than 5 years.
Mr. Pokrzywinski is a Chartered Financial Analyst and holds a Business Degree
from the University of Wisconsin.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE PAST 12 MONTHS?

The fixed-income market benefited from low inflation and an overall "flight to
quality" stemming from the Asian economic crisis. Many investors worldwide moved
assets from volatile global regions to U.S. Government securities. The yield on
the 30-year Treasury dropped to a record low of 5.57% in June of 1998. Given
this positive economic backdrop, the WM Short Term High Quality Bond Fund's
total return for the 12 months ended June 30, 1998 was 5.91%, for Class A shares
(2.38% adjusted for the maximum sales charge). Because the Fund has a short
duration, it is less affected by changes in interest rates, and is less
sensitive to fluctuations as long-term Funds. The Fund is managed to provide
income to its shareholders and the 30-day SEC yield of the portfolio was 5.30%
at the close of the period (4.73% for B shares).

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

Interest rates dropped during the past year. The effects of this was positive
for the Fund and its total return performance. However, the income stream
provided the largest impact on performance. Our position in asset-backed
securities also helped to boost performance as that class provided relative
strength. Because of the drop in interest rates, mortgage-backed securities
tended to underperform other sectors as investors were nervous about the
prospects for increased prepayments. Corporate yields did not fall as much as
other fixed-income sectors towards the end of the period so we took advantage of
good relative prices to add to these positions.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS THAT HAVE HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

During the past 12 months, the Short Term Global Government Fund was merged into
this Fund and WM Advisors took over the management of the merged Fund. Due to
the merger and the inflows of assets, we used the cash to restructure the
portfolio favoring corporate bonds and Treasury notes. We also decreased
exposure to mortgage-backed securities which helped performance in the second
quarter of 1998. Although the overall management outlook remains the same, the
Fund's average maturity and duration--a measurement of price sensitivity to
changes in interest rates--increased slightly in the period. We also maintained
the Fund's position in asset-backed securities during the period.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

The long-term strategy of the Fund is to continue to have a diversified
portfolio of high-quality securities with a yield advantage. The Fund will
invest a significant percentage of its holdings in corporates, asset-backed, and
mortgage-backed securities. Over a complete cycle of interest rates, mortgage
securities should continue to provide a high level of income. The Fund will
maintain its short-term structure to lessen price volatility relative to long-
term assets. We will shift the sector allocations depending upon our outlook for
interest rates and the overall business cycle.

WHAT IS OUR OVERALL ECONOMIC OUTLOOK FOR THE NEXT 12 MONTHS?

Over the next 12 months we expect the economy to exhibit moderate growth. The
effects of the fallout in Asia should help keep growth and inflation under
control. Global price competition and the higher levels of imports into the
United States should support this scenario. Overall, there continues to be
worldwide structural forces at work (fiscal austerity, demographics, excess
capacity) which should keep inflation under control for the next 3-5 years.
Although there will be periods of volatility, we believe the overall interest
rate trend is lower. These aforementioned factors should continue to produce
slow growth and keep price pressures at bay.

CALIFORNIA MUNICIPAL FUND

PORTFOLIO MANAGER:
JOSEPH PIRARO
VAN KAMPEN INVESTMENTS

Mr. Piraro joined the company in 1992, and serves as Vice President and
portfolio manager of Van Kampen Investments. He has had primary portfolio
management responsibility for the California Municipal Fund since May 1992.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE PAST 12 MONTHS?

The strength of the economy, the decision by the Federal Reserve Board not to
adjust short-term interest rates, and the financial problems in Asia
significantly affected the U.S. bond markets. As inflation remained benign, the
bond market rallied throughout the reporting period. The yield of the 30-year
Treasury bond, which moves in the opposite direction of its price, fell from
6.79% on June 30, 1997 to 5.63% a year later.

The impact of the Asian financial crisis was evident in the underperformance of
the tax-exempt market relative to treasuries. As problems in Asia have continued
and the U.S. Dollar has risen relative to Asian currencies, demand for
treasuries has increased. This "flight to quality" drove the yield on the 30-
year Treasury down to historically low levels. The Federal Government's surplus
also caused a reduction in issuance of treasury securities, resulting in fewer
bonds to meet this strong demand.

Because of supply and demand fundamentals, the municipal market did not perform
as well as treasuries during the period. Historically, low interest rates have
fueled refundings as well as new borrowings, resulting in a 51 percent increase
in issuance year-to-date over 1997. Although these lower rates were not quite as
attractive to investors seeking yield, demand did keep pace with supply. The
good ratio of municipal yields to Treasuries attracted some individuals as well
as cross-over buyers (institutions who typically purchase taxable securities).
At the end of the reporting period, the Bond Buyer 40 Index (an index of 40
actively traded, long-term investment grade securities) had a yield of 5.22%, or
93% of long-term treasuries.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

The duration (a measure of the price sensitivity to changes in interest rates)
of the portfolio at the end of the period was 7.3 years, slightly shorter than
our benchmark 8.3 years. As market conditions caused duration to shorten over
the reporting period, we offset the market effect through the acquisition of
long-term discount securities and the sale of premium bonds. While the duration
of the securities in the portfolio was shorter than our target, we felt it was
more beneficial to our shareholders to maintain the core positions in the
portfolio than to lengthen the duration.

As of June 30, 1998, the 30-day SEC yield of the Fund's Class A shares was 4.24%
or 7.74% on a tax-equivalent basis (3.69% and 6.74% for B shares).2 Yield
spreads between credit ratings remain very narrow. As a result, most
acquisitions focused on AAA-rated securities, which we felt had more relative
value than lower-rated paper. While we continue to seek non-rated offerings to
add yield to the Fund, we saw few opportunities that rewarded the investor for
the additional credit risk. On June 30, 1998, over 62 percent of assets were
AAA-rated, up slightly over the period. The quality sector of the market
performed well during the year.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON THE FUND'S PERFORMANCE?

Health care exposure increased by almost 10 percent to 14 percent of assets.
Although most of these bonds are insured, they tend to trade at a small yield
advantage over other sectors. Additionally, health care continues to be the best
performing sector of the revenue bond index. As a result of this increase, we
decreased our exposures to the transportation, tax district, and multi-family
housing sectors. We also decreased our exposure to securities that are subject
to the Alternative Minimum Tax (AMT). As the yield spread between AMT and non-
AMT offerings narrowed, we saw an opportunity to sell several positions at a
profit and, at the same time, use some of the proceeds of these sales to invest
in discount securities to extend duration.

The Fund has excellent diversification, with exposure to 15 industries. Because
of the attractive yields on our current holdings, as well the good balance
between sectors, we do not expect significant changes in the near future. The
credit quality of the portfolio remains very high, and we will maintain that
level given the demand for quality California securities and the relative
attractiveness of these bonds.

WHAT IS OUR OVERALL ECONOMIC OUTLOOK FOR THE NEXT 12 MONTHS?

Despite the strong economy, inflation has remained dormant as a result of weak
commodity prices and a strong Dollar. There are, however, hints that the good
news on inflation could be coming to an end. The various domestic factors that
might have prompted serious fears about inflation were offset by the Asian
situation. Currently, the situation overseas could create a dilemma. After the
decision to support the Yen, raising U.S. interest rates would be counter-
productive since it would strengthen the U.S. Dollar. However, if competition
from Asia does not sufficiently cool the U.S. economy, the Fed may feel
compelled to raise short-term rates, which would put upward pressure on long-
term rates. With its status as a shipping and import/export hub, any ripples
that rock Asia are likely to be felt in California.

We will maintain our slightly bullish duration, as we expect the low interest
rate environ-ment to continue in the near term, but we are not overly bullish on
the market as a whole. Unless the taxable market makes a significant move, we
expect municipal yields to remain within their recent trading range. The supply
of municipal issues looks like it will remain strong, possibly setting an annual
record for the industry. As the second largest state issuer, we expect the
California market will play a big role in this surge of volume.

2 Tax-equivalent yield is based on Federal income taxes at 39.6% and California
  income taxes at 9.3%, and the federal deduction of state taxes paid. 

  A portion of income may be subject to some State and/or local taxes, and for
  certain investors, may be subject to the federal alternative minimum tax
  (AMT).

Because of supply and demand fundamentals, the municipal market did not perform
as well as treasuries during the period. Historically, low interest rates have
fueled refundings as well as new borrowings, resulting in a 51 percent increase
in issuance year-to-date over 1997. Although these lower rates were not quite as
attractive to investors seeking yield, demand did keep pace with supply. The
ratio of municipal yields to Treasuries attracted some individuals as well as
cross-over buyers (institutions who typically purchase taxable securities). At
the end of the reporting period, the Bond Buyer 40 Index (an index of 40
actively traded, long-term investment grade securities) had a yield of 5.22%, or
93% of long-term treasuries. As of June 30, 1998, the Fund's Class A shares had
a 30-day SEC yield of 3.49%, with a tax-equivalent yield of 6.37% (2.90% and
5.29% respectively for B shares)./2/

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

California municipal issuance was up 80% in 1998 relative to the same period in
1997. Through the end of the first quarter, over 60 percent of new issue volume
was insured paper. We focused on AAA-rated insured discount securi-ties for two
reasons. First, the yield spread between insured and lower rated offerings
continues to be very narrow. As a result, we see greater relative value in
quality securi-ties, as we feel the higher yield offered on lower rated paper
does not adequately reward the investor for the additional credit risk. Second,
as yields decline, the duration (a measure of price sensitivity to interest
rates) of the portfo-lio shortens. To offset this market effect, we invested in
discount securities to maintain a neutral duration compared to our benchmark. At
the end of the reporting period, the portfolio had a duration of 5.3 years,
compared to the Lehman Brothers California Insured Municipal Bond Index duration
of 5.8 years.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON THE FUND'S PERFORMANCE?

Our exposure to the transportation sector increased by 9% and now totals 16% of
assets, due to a purchase early this year of Los Angeles County Metropolitan
Transit Authority. This position is our largest exposure to a single issuer and
is AAA-rated. We decreased our exposure to the general purpose, high education
and multi-family housing sectors. At the end of the reporting period, 86% of
assets were insured, slightly higher than the 80 percent mandated by the
prospectus. Given the continued demand for quality California securities, we
will maintain our high credit quality.

WHAT IS OUR OVERALL ECONOMIC OUTLOOK FOR THE NEXT 12 MONTHS?

Despite the strong economy, inflation has remained dormant as a result of weak
commodity prices and a strong dollar. There are, however, hints that the good
news on inflation could be coming to an end. The various domestic factors that
might have prompted serious fears about inflation were offset by the Asian
situation. Currently, the situation overseas could create a dilemma. After the
decision to support the Yen, raising U.S. interest rates would be counter-
productive since it would strengthen the U.S. Dollar. However, if competition
from Asia does not sufficiently cool the U.S. economy, the Fed may feel
compelled to raise short-term rates, which would put upward pressure on long-
term interest rates. With its status as a shipping and import/export hub, any
ripples that rock Asia are likely to be felt in California.

We will maintain our slightly bullish duration, as we expect the low interest
rate environ-ment to continue in the near term, but we are not overly bullish on
the market as a whole. Unless the taxable market makes a significant move, we
expect municipal yields to remain within their recent trading range. The supply
of municipal issues looks like it will remain strong, possibly setting an annual
record for the industry. As the second largest state issuer, we expect the
California market will play a big role in this surge of volume.

2 Tax-equivalent yield is based on Federal income taxes at 39.6% and California
 income taxes at 9.3% and the federal deduction of state taxes paid.

 A portion of income may be subject to some state and/or local taxes, and for
 certain investors, may be subject to the federal alternative minimum tax (AMT).

FLORIDA INSURED MUNICIPAL FUND

PORTFOLIO MANAGER:
THOMAS BYRON
VAN KAMPEN AMERICAN CAPITAL MANAGEMENT, INC.

Mr. Byron, Vice President of Van Kampen, has over 15 years of experience with
the Company. He has been with Van Kampen since 1981 and held the position of
Head Buyer and Manager, with responsibility for all tax-exempt and taxable UITs.
Mr. Byron has had primary portfolio management responsibility for the WM Florida
Insured Municipal Fund since
January 1997.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE PAST 12 MONTHS?

The strength of the economy, the decision by the Federal Reserve Board not to
adjust short-term interest rates, and the financial problems in Asia
significantly affected the U.S. bond markets. As inflation remained benign, the
bond market rallied throughout the reporting period. The yield of the 30-year
Treasury bond, which moves in the opposite direction of its price, fell from
6.79% on June 30, 1997 to 5.63% a year later.

The impact of the Asian financial crisis was evident in the underperformance of
the tax-exempt market relative to treasuries. As problems in Asia have continued
and the U.S. Dollar has risen relative to Asian currencies, demand for
treasuries has increased. This "flight to quality" drove the yield on the 30-
year Treasury down to historically low levels. The Federal Government's surplus
also caused a reduction in issuance of treasury securities, resulting in fewer
bonds to meet this strong demand.

1 Index total returns were calculated from 6/30/93 to 6/30/98. The Lehman
  Brothers Municipal Bond Index is a total return performance benchmark for the
  long-term, investment-grade, tax-exempt bond market. The index assumes
  reinvestment of all dividends/distributions, and does not reflect any asset-
  based charges for investment management or other expenses. Past investment
  performance does not guarantee future performance. The returns shown for the
  Fund assume reinvestment of all dividends/distributions by the shareholder.

  During the period noted, the Advisor waived a certain portion of fees and
  absorbed other expenses, and credits were allowed by the Custodian. In the
  absence of the waiver and absorption of other expenses or credits, yield and
  total return would have been lower.

The performance of the Class B Shares and Class S Shares was different than that
indicated by the lines shown above for the Class A Shares, based on the
differences in sales loads and fees paid by Class B and Class S shareholders.

index of 40 actively traded, long-term investment grade securities) had a yield
of 5.22%, or 93% of long-term treasuries.

Income remains an important part of managing the Fund; as of June 30, 1998, the
Fund's Class A shares had an SEC yield of 4.03% or 7.36% on a tax-equivalent
basis (3.47% and 6.33% for B shares)./2/

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

The strong supply of municipal bonds benefited the portfolio as there were
plenty of quality bond issues coming to market. Issuance for the state was up
34% in 1998. Of total new volume, insured issuance accounted for 79% of the
state's supply through the end of the first quarter. This supply provided for a
highly diversified portfolio.

At the end of the reporting period, the portfolio had a duration (a measure of
the price sensitivity to changes in interest rates) of 6.9 years, compared to
the Lehman Brothers Florida Municipal Bond Index duration of 7.7 years. The long
duration benefited the Fund as rates fell throughout the period. While we did
find some attractive offerings during the period, we maintained the core
position of the Fund.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON THE FUND'S PERFORMANCE?

We increased our exposure to the water/sewer sector by 6%, and decreased
holdings in the airport and retail utility industries. The portfolio has a very
high credit quality, with 82% of assets AAA rated. The remaining 18% of assets
were evenly split between BBB-rated and non-rated holdings to strengthen the
overall yield.

WHAT IS OUR OVERALL ECONOMIC OUTLOOK FOR THE NEXT 12 MONTHS?

Despite the strong economy, inflation has remained dormant as a result of weak
commodity prices and a strong U.S. Dollar. There are, how-ever, hints the good
news on inflation could be coming to an end. The various domestic factors that
might have prompted serious fears about inflation were offset by the Asian
situation. Currently, the situation overseas could create a dilemma. After the
decision to support the Yen, raising U.S. interest rates would be counter-
productive since it would strengthen the U.S. Dollar. However, if competition
from Asia does not sufficiently cool the U.S. economy, the Fed may feel
compelled to raise short-term rates, which would put upward pressure on long-
term interest rates.

We will maintain our slightly bullish duration policy, as we expect the low
interest rate environment to continue in the near term, but we are not overly
bullish on the market as a whole. Unless the taxable market makes a significant
move, we expect municipal yields to remain within their recent trading range.
The supply of municipal issues looks like it will remain strong, possibly
setting an annual record for the industry. The Florida economy remains strong
and vibrant, with tourism, construction and other key sectors on the rise. Our
strategy going forward will be to take advantage of the new issue market, which
we expect to be highly active. We believe the portfolio is positioned to provide
an attractive level of tax-exempt income without undue risk.

GROWTH FUND

PORTFOLIO MANAGER:
WARREN LAMMERT
JANUS CAPITAL CORPORATION

Mr. Lammert is a graduate of Yale University and the London School of Economics.
He first joined Janus in January 1987 and has been portfolio manager of the
Growth Fund since its inception. He is a Chartered Financial Analyst.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE PAST 12 MONTHS?

For the past 12 months, the stock market has put up very impressive numbers,
with the S&P 500 Index gaining over 30%. Meanwhile, the Fund returned 35.43%.

Looking back, market performance has been quite volatile over the past year.
After a broad market rally last summer, equities came under pressure by year-end
amid a few disappointing announcements and the growing financial crisis in Asia.
We took this opportunity, however, to expand our positions in several promising
technology stocks, which have performed well for us. Domestic equities posted
impressive gains in the first part of 1998 and managed to build on these results
early in the second quarter. Then the market experienced renewed volatility,
reflecting mounting concerns over Asia and related uncertainty surrounding
corporate profits. Consequently, stocks lost ground in late May and early June.
Equities proved resilient, however, and managed to end the second quarter of
1998 with a strong rally, thanks to a significant drop in long-term interest
rates and a resurgent technology sector.

Portfolio returns benefited as several of our issues came alive at the end of
the period, adding to strong results accumulated since the start of the year.
Robust portfolio performance continues to reflect our emphasis on companies with
dominant franchises and exceptional earnings growth.

indicated by the lines shown above for the Class A Shares, based on the
differences in sales loads and fees paid by Class B and Class S shareholders.

1  Index total returns were calculated from 4/30/93 to 6/30/98. The Standard &
   Poor's 500 Composite Index (S&P 500) represents an unmanaged weighted index
   of 500 industrial, transportation, utility, and financial companies widely
   regarded by investors as representative of the stock market. The index
   assumes reinvestment of all dividends/distributions, and does not reflect any
   asset-based charges for investment management or other expenses. Past
   investment performance does not guarantee future performance. The returns
   shown for the Fund assume reinvestment of all dividends/distributions by the
   shareholder.

   During the period noted, the Advisor waived a portion of its management fees
   and absorbed other expenses, and credits were allowed by the Custodian. In
   the absence of the waivers and absorption of other expenses or credits, yield
   and total return would have been lower.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

The large-stock indices continued to be tough competitors for active managers,
in part because investors are favoring large-capitalization stocks for their
perceived earnings stability and liquidity. Additionally, the trend toward
indexing continues to bolster the stocks that comprise the S&P 500 Index, as new
money chases returns. However, we are starting to see more of an emphasis on
earnings growth, because broad S&P 500 profits are coming under increasing
pressure from Asian weakness and rising labor costs. As a slowdown in corporate
earnings continues to unfold, those companies with more positive earnings
characteristics should receive renewed attention, regardless of their size. We
are confident that our research will continue to identify those companies can
meet or exceed their earnings projections, and these companies will be rewarded
for their performance.

WERE THERE ANY SHIFTS IN THE FUNDS PORTFOLIO'S HOLDINGS/SECTORS THAT HAVE HAD A
SIGNIFICANT IMPACT ON PERFORMANCE?

The Portfolio reflects our commitment to a variety of themes, particularly
technology, pharmaceuticals, cable and financial services. In 1998, we created a
more focused portfolio, shortening our list of names and trimming a number of
smaller positions.

Among our technology stocks, our positions in Dell, Microsoft, and America
Online (AOL) have all performed well. Dell continues to exploit its highly-
successful business model, despite a generally weak environment for PC manufac-
turers. Meanwhile, Microsoft advanced strongly after over-coming concerns
related to the Justice Department's antitrust suit. The company is beginning a
major new product cycle with the current launch of Windows 98 and the roll-out
of Windows NT 5.0 later this year. Additionally, AOL, supported by the growing
acceptance of the Internet as a new media avenue, continues to perform well.

We have also succeeded with our Internet positions, including Amazon.com, the
leading Internet book and music retailer. Amazon.com was added to the Fund
during the second quarter, and the stock price more than doubled over a 
thirteen-day period in June. While we are excited about Amazon.com's prospects,
given its strong brand name and explosive growth, we also realize that such
quick gains can easily reverse themselves. Consequently, we opted to trim the
position at a significant profit.

Several of our pharmaceutical stocks have also performed exceptionally well,
including Warner-Lambert and Pfizer. Both companies continue to experience
strong results from their new product launches, effectively driving revenues
higher. More recently, we also added Cognizant, which owns IMS, a provider of
prescription and market share data for pharmaceutical companies.

During the period, a number of developments helped to validate our thesis on the
cable industry--an area that remains very compelling. After years of equipment
and infrastructure upgrades, cable operators are on the verge of rolling out a
two-way digital platform that will allow a variety of new services, including
telephony data and expanded video offerings. These factors, combined with a
dramatic decline in capital expenditures, create a promising outlook. As a
result, we built positions in Comcast, Time Warner, Media One, and Tele-
Communications, Inc. (TCI), all of which performed very well. In addition,
AT&T's recent decision to purchase TCI highlights the value of the cable
pipeline, and we believe the combined entity will unlock a variety of important
synergies moving ahead.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

We remain generally positive on the outlook for equities; however, Asian
weakness and the impact of the strong Dollar remain a concern. For this reason,
we emphasize companies with robust earnings growth that are well-insulated from
Asia's downturn. As always, we rely on Janus' strategy to find promising
individual companies with strong fundamentals and positive earnings growth
potential. We also continue to follow our disciplined portfolio approach and are
willing to trim positions that are fully priced or where our earnings estimates
appear to be in jeopardy.

WHAT IS OUR OVERALL ECONOMIC OUTLOOK FOR THE NEXT 12 MONTHS?

Looking ahead, Asia's continuing economic difficulties contribute an element of
uncertainty to global markets. Japan's economy has moved into a severe
recession, brought about by the Japanese government's failure to enact
meaningful economic reforms and by its fragile banking system. Additionally,
the recent weakness in the Yen versus the U.S. Dollar highlights the currency
risk that still lingers throughout the region. On the positive side, Asia's
slowdown has been an effective brake on the global economy and has helped keep
domestic inflation in check, despite an impressive U.S. expansion. As a result,
domestic interest rates continue to reflect these positive fundamentals and
remain at very low levels.

EMERGING GROWTH FUND

PORTFOLIO MANAGERS:
DAVID SIMPSON
LINDA WALK
WM ADVISORS, INC.

The Fund is co-managed by David Simpson and Linda Walk of WM Advisors, Inc. Mr.
Simpson and Ms. Walk began managing the fund on March 23, 1998. Both managers
are Chartered Financial Analysts have experience in small-cap management.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE PAST 12 MONTHS?

The Fund's Class A shares appreciated nearly 13% (6.75% adjusted for the maximum
sales charge) during the 12-month period ended June 30, 1998. The performance
was slightly under the Russell 2000 Index and significantly outpaced the
S&P/Barra small-cap growth index (a measure of growth style small-cap stocks).

The performance of the WM Emerging Growth Fund was impacted by the under-
performance of small-capitalization companies relative to large-capitalization
companies. During the past 12-months, large-caps appreciated nearly twice as
much as stocks of smaller companies. The Fund has lagged both the S&P 500 and
the Russell 2000 due to weakness in small-cap growth stocks, particularly small-
cap technology stocks. These equity classes were especially

affected by concerns over the effects of the Asian crisis. A number of companies
preannounced disappointing earnings as weakness in Asia was compounded by a
slowdown in PC demand.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

Although the Fund reported positive performance, the "flight to large", liquid
stocks hampered the performance relative to the S&P 500. Investors poured money
into the largest domestic companies with more predictable earnings streams
during this period of market uncertainty. With the collapse in Asia, it was
difficult to predict the underlying effects on domestic companies. The small-cap
technology firms have not yet rebounded and their performance was not as strong
as some of the larger technology firms. Examples include Radisys and In Focus
Systems. Radisys designs and produces embedded computer solutions, while In
Focus builds portable projectors for multimedia presentations.

Both companies have struggled recently, but we maintain our positions as our
long-term outlook looks good.

Prior to March, the Fund was managed by earnings momentum--a growth style.
Stocks were bought on earnings growth and sold when prices fell. Although large-
cap growth investing led the market, this style has not performed well in the
small-cap market recently. The Fund is now managed with more of a value style--
looking for strong companies at good prices. We will now use near-term weakness
as an opportunity to add to positions in companies where long-run prospects are
strong.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAVE HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

We took over management of the Fund in March of 1998 and began to subtly reshape
the portfolio. We increased concentrations in industries such as technology and
health-care and reduced holdings in consumer-discretionary stocks, particularly
restaurants. We believe these new positions will add to performance over the
long-run, as the industries are growing faster than the economy as a whole.

We intend to shift focus to stocks with lower relative valuations. These stocks
may be currently out of favor, but with strong fundamentals and good business
prospects. The net effect on the Fund will be a lower overall price-to-earnings
ratio as these more moderately-priced companies are included in the portfolio.
This will work to reduce risk given the high valuations of domestic equities.

We had success with Icos, a biopharmaceutical firm that currently has eight
products in phase II trials for approval. A medical equipment firm, ATL
Ultrasound, was recently purchased and has been a strong performer.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

The market has been dominated by the large-cap stocks. We believe this trend
will not continue in the long-run, and valuations of these very large companies
may have reached excessive levels. It seems likely the performance gap between
large and small companies will close and our valuation discipline will reward
our shareholders over the long run. The Fund focuses on companies with good
management teams and excellent long-term prospects. We attempt to buy stocks
below their intrinsic value with the expectation their value will ultimately be
realized.

It is important to maintain your long-term focus to small-cap equity investing.
These stocks tend to be more volatile, but long-term results have been very
favorable.

WHAT IS OUR OVERALL ECONOMIC OUTLOOK FOR THE NEXT 12 MONTHS?

The domestic economy continues to support strong growth without significant
inflation. However, it is unclear if all of the effects of Asia have rippled
through the U.S. economy. Currently, the effects of Asia have only muted growth
and inflation. Should the impact be more profound, the markets could be upset by
a substantially weaker economy than was previously forecasted. The tight labor
market could cause inflationary pressures, although currently inflation is well
contained. These factors will all play an important role in the overall
performance of financial assets, as stocks benefit from a low inflation, low
interest rate environment.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE PAST 12 MONTHS?

For the 12 months ended June 30, 1998, the most significant factor affecting the
Fund's performance was the Asian region's economic and financial problems. These
problems started very early in the period, with the Thai Baht being devalued on
July 2, 1997. After that point, having almost any exposure to Asia was a
liability. Across the region, economic growth continued to contract, and the
picture is unlikely to improve

dramatically any time soon. The near-term earnings outlook from most companies
was correspondingly poor, and in some cases, it was difficult to gauge earnings
prospects at all, especially given the absence of currency stability. Investor
sentiment, which had picked up briefly in the first quarter of 1998, has once
again turned overwhelmingly bearish in the second quarter, exacerbated by
growing worries about Japan.

Europe, whose markets showed near-universal gains, rose throughout the period on
continued economic improvement and robust profit growth. In the second quarter
of 1998, Europe's performance was even stronger from the perspective of U.S.
Dollar-based investors, as most regional currencies rose vs. the U.S. Dollar,
bucking the recent trend.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

The collapse in Asia during the second half of 1997 was addressed by largely
reducing holdings in the region. Many positions were sold, but still had an
adverse effect on performance. As of June 30, the Fund had 77% of its
investments in Europe and 14% in Asia.

In the first quarter of 1998, foreign stock markets staged a strong rally,
bouncing back convincingly after 1997's fourth quarter. By region, the most
impressive results came from Europe, where markets showed across-the-board
strength, propelled by robust corporate profits, merger speculation and
increased optimism toward the prospects for European Monetary Union. Asian
markets generally rose as well, with several of last year's hardest-hit markets
rallying sharply.

Non-U.S. equity markets had mixed results in the second quarter of 1998, with
performance divided almost entirely along regional lines.

Asian/Pacific markets mostly declined, with several falling sharply, amid
renewed worries over the region's economic and financial straits. Adding a
considerable amount of fuel to the fire was a further deterioration of Japan's
economy, as a healthy Japan is requisite for a broad, sustained regional
recovery. Asia's weakness had spillover effects on Latin American and, to a
lesser extent, Eastern European markets, whose troubles were compounded by the
threat of an economic implosion in Russia. Losses in all of these markets were
magnified in Dollar terms, as most countries' currencies fell in value against
the U.S. Dollar.

The safe harbor through the period was, once again, Europe, where most markets
showed gains. Because of the continued strength there, as well as the
uncertainty and underperformance in the Asian region, we continued to focus on
Europe.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

Our continued shift away from a lagging Asian region in favor of Europe has
helped the performance of the Fund. We further trimmed our Asian-Pacific
exposure during the period, reflecting our ongoing concerns about the region. In
particular, the Fund's remaining exposure to Japan was concentrated in a handful
of strong, globally-competitive companies, primarily electronics firms, as these
companies continue to generate strong earnings gains. Asian economic weakness
notwithstanding, their stocks remain reasonably priced vs. those of their global
peers.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

We expect to maintain the Europe-heavy positioning for at least the near term,
given the tailwind that continues to drive these markets. Economic growth, which
has improved significantly over the past year, continues apace, with most
continental European economies projected to expand by 2.5%-3% over the next 12
months. Growth in Europe stands to be even higher in 1999, barring a major
external shock (e.g., a total collapse in Russia or a significant tightening of
U.S. monetary policy).

Also, the interest-rate backdrop remains supportive, local-investor sentiment
towards stocks grows increasingly bullish, and foreign sentiment towards Europe
remains positive. In short, we maintain our positive outlook regarding Europe,
and all things considered, we are comfortable with our current level of
exposure.

Economic growth across the Asian region continues to contract, and the picture
is unlikely to improve dramatically any time soon. Given this, we have deemed
it prudent to maintain a cautious posture, limiting our exposure to only those
stocks in which we have a very high level of conviction. This short list of
names is concentrated primarily in Hong Kong, Singapore, South Korea and New
Zealand.

PORTFOLIO MANAGER:
STEPHEN C. SCOTT
WM ADVISORS, INC.

The Strategic Asset Management Portfolios are managed by Senior Portfolio
Manager, Steve Scott. Mr. Scott is a pioneer in the business of asset
allocation, with over 28 years experience. He is the architect and founder of

University, Long Beach.

PERFORMANCE REVIEW

The Strategic Asset Management Strategic Growth Portfolio returned 19.87%
(13.27% adjusted for the maximum sales charge) for the year ended June 30, 1998.
The year was marked with market volatility and change. During the period, the WM
Group of Funds were introduced as a result of the merger between Sierra and
Composite Funds. We are pleased to report the architectural design, fundamental
policies, and management of the SAM Portfolios continued to provide benefit to
shareholders. In addition, the continuity of asset management personnel for the
SAM Portfolios remained in place. Although the Fund underperformed its benchmark
index/3/(the S&P 500), it is managed with an effort to reduce volatility
relative to single asset-class investments. The Fund participated in the
appreciation of the large-cap market, but the underperformance of small-caps and
international stocks hurt overall performance.

ECONOMIC / MARKET REVIEW

Strong economic fundamentals drove the financial markets forward in the 12-month
period ended June 30, 1998. Low unemployment, strong consumer spending, low
interest rates, and a booming housing market provided some

of the positive backdrop for economic growth. While both fixed-income and equity
investments posted very positive results, it was not without volatility. The
crisis in the Far East sent shock waves throughout the financial markets
worldwide in the fourth quarter of 1997. The extent to which the Asian collapse
ultimately impacts U.S. and European growth is not yet known, but the
uncertainty is likely to increase market volatility until a turnaround becomes
visible.

In the equity markets, a dichotomy of results relative to market capitalization
continued throughout the period. Large capitalization companies (S&P 500) have
appreciated three times as much as small-caps (Russell 2000) during the first
six months of 1998; they returned twice as much as small-caps over the past year
ended June 30, 1998. Style differences also provided a disparity in results in
1998, as growth stocks significantly outperformed value stocks in both the 
large- and the mid-sized capitalization areas. Small-cap growth continued to be
the worst performing domestic equity sector. The backlash of the Asian currency
crisis on global equity markets was quite pronounced, as results across Asia and
Latin America were very poor. Europe on the other hand, proved resilient,
outpacing even the high flying large-cap domestic markets in the period.

INVESTMENT STRATEGY

The SAM Strategic Growth Portfolio remained diversified in four equity funds,
representing six major asset classes. This diversification enables the Portfolio
to manage risk during periods of market volatility. The diversified portfolio of
equity classes shield the Portfolio from drastic market swings in one specific
area of the global markets.

The overall investment strategy for the period was to:

 .    Increase exposure to European holdings (17%) to take advantage of prospects
     for strength in the region.
 .    Overweight (63%) the equity portion of the portfolio in core domestic mid-
     to large-capitalization stocks.

REVIEW OF PORTFOLIO ALLOCATIONS

We have positioned the Portfolio to take advantage of current market trends as
well as to manage overall portfolio risk levels. The Fund benefited from its
emphasis in mid- to large-cap holdings, whose strong performance offset
underperformance by the small-cap position. Prior to the Asian collapse, the
Portfolio was underweighted in international stocks which aided both performance
and the overall risk of the Portfolio. Recently, we have increased exposure
overseas due to a positive outlook in Europe. We also reduced our concentration
in the very highly-valued U.S. domestic market. We removed our position in 
fixed-income securities and now maintain a nearly (97%) fully-invested
Portfolio. This reflects our positive long-term outlook on equities, and we feel
the diversified positions should help to manage the overall risk levels of the
Strategic Growth Portfolio given the high valuation levels of domestic equities.

OUTLOOK

Inflation remains weak and interest rates are low. Both the Bundesbank (Europe)
and the Federal Reserve Board (U.S.) have announced they are closely watching
inflation and maintaining a bias towards raising interest rates. If the negative
impact from Asia is less than expected, and if consumption remains strong, the
Federal Reserve may be forced to adjust interest rates later in the year. This
would be done to prevent the economy from overheating. We believe inflation is
manageable and Chairman Greenspan has been very effective in interest rate
policy during this new paradigm.

We maintain our long-term positive outlook on the equity markets. Although there
will always be periods of volatility, the overriding economic fundamentals
provided by globalization and efficiency improvements brought about by
technological enhancements create a dynamically-positive environment for stocks.
Current low levels of interest rates and inflation also provide support for
equities. We are also bullish on foreign equities, especially Europe, in where
an improving structural foundation also furnishes a positive long-term forecast.
In the same respect, we are reluctant to extend portfolio risk much beyond
current levels due to the high equity valuations. We prefer to make allocation
changes only if diversification can be maintained and portfolio risk is not
measurably extended.

PERFORMANCE REVIEW

The Strategic Asset Management Conservative Growth Portfolio returned 15.18%
(8.84% adjusted for the maximum sales charge) for the year ended June 30, 1998.
The year was marked with market volatility and change. During the period, the WM
Group of Funds were introduced as a result of the merger between Sierra and
Composite Funds. We are pleased to report the architectural design, fundamental
policies, and management of the SAM Portfolios continued to provide benefit to
shareholders. In addition, the continuity of asset management personnel for the
SAM Portfolios remained in place. The Fund beat its benchmark index for the past
year and since inception, while being managed with an effort to volatility
relative to single asset-class investments. Long-term results continue to
provide a premium over inflation; since inception, the Fund returned 10.43%
above the rate of inflation (9.61% adjusted for the maximum sales charge)/3/.

ECONOMIC / MARKET REVIEW

Strong economic fundamentals drove the financial markets forward in the 12-
month period ended June 30, 1998. Low unemployment, strong consumer spending,

The SAM Conservative Growth Portfolio remained diversified in six funds,
representing eight major asset classes. This broad diversification enables the
Portfolio to manage risk during periods of market volatility. Asset classes,
ranging in risk levels from cash to foreign stocks, shield the Portfolio from
drastic swings in one specific area of the financial markets.

The overall investment strategy for the period was to:

 .    Positioned a portion of the Portfolio in cash and fixed-income to help
     manage risk.
 .    Increase exposure to European holdings (17%) to take advantage of prospects
     for strength in the region.
 .    Overweight (50%) the equity portion of the portfolio in core domestic mid-
     to large-capitalization stocks.

We have positioned the Portfolio to take advantage of current market trends as

overseas due to a positive outlook in Europe. We also reduced our concentration
in the very highly-valued U.S. domestic market. These moves further diversify
the assets and, in conjunction with the cash position, should work to manage the
overall risk levels of the Conservative Growth Portfolio given the high
valuation levels of domestic equities.

Inflation remains weak and interest rates are low. Both the Bundesbank (Europe)
and the Federal Reserve Board (U.S.) have announced they are closely watching

PERFORMANCE REVIEW

The SAM Balanced Portfolio returned 14.32% (8.03% adjusted for the maximum sales
charge) for the year ended June 30, 1998. The year was marked with market
volatility and change. During the period, the WM Group of Funds were introduced
as a result of the merger between Sierra and Composite Funds. We are pleased to
report that the archi-tectural design, fundamental policies, and management of
the SAM Portfolios continued to provide benefit to shareholders. In addition,
the continuity of asset management personnel for the SAM Portfolios remained in
place. The Fund continues to beat its benchmark index for all periods/4/ while
being managed with an effort to reduce volatility relative to single asset-class
investments. Long-term results continue to provide a premium over inflation;
since inception, the Fund returned 8.36% above the rate of inflation (7.55%
adjusted for the maximum sales charge)/4/.

ECONOMIC / MARKET REVIEW

Strong economic fundamentals drove the financial markets forward in the year
ended June 30, 1998. Low unemployment, strong consumer spending, low interest
rates, and a booming housing market provided some of the positive backdrop for
economic growth. While both fixed-income and equity investments posted very
positive results, it was not without volatility. The

1 The Balanced Portfolio's benchmark is a blended mix of capital market indices
  that is intended to represent a proxy for Portfolio performance. The benchmark
  allocation is as follows: 25% Lehman Bros Mutual Fund Short (1-5) Gov/Corp
  Index, 25% Salomon Bros. 90-day T-Bills, 20% Lehman Bros Mortgage Index, 15%
  S&P 500, and 15% MSCI EAFE + Emerging Markets. Past investment performance
  does not guarantee future performance. The returns shown for the Portfolio
  assume reinvestment of all dividends/distributions by the shareholder.

5 All performance shown prior to the November 1, 1996 asset conversion date (the
  date on which the majority of existing SAM clients voluntarily exchanged into
  the new SAM Portfolios) for the Sierra Asset Management Portfolios represents
  the performance of the Sierra Asset Management Account ("SAM Account"), a
  discretionary asset allocation service that invested in the Sierra Trust
  Funds. The SAM Account was not registered as an investment company under the
  Investment Company Act of 1940 ("Act") and therefore, was not subject to
  certain restrictions that the Act imposes. If the SAM Account had been
  registered under the Act, its performance may have differed significantly.

  For the period November 1, 1996 to June 30, 1998, the Advisor waived its
  management fee and absorbed other expenses, the Administrator waived a portion
  of its management fee, and Custodian allowed credits. Prior to November 1,
  1996, the Advisor, Administrator and Distributor waived a portion of their
  management or distribution fees, the Advisor and Administrator absorbed other
  expenses, and the Custodian allowed credits. In the absence of the waivers,
  absorption of other expenses, or credits, yield and total return would have
  been lower.

crisis in the Far East sent shock waves throughout the financial markets
worldwide in the fourth quarter of 1997. The extent to which the Asian collapse
ultimately impacts U.S. and European growth is not yet known, but the
uncertainty is likely to increase market volatility until a turnaround becomes
visible.

Although there were pockets of slowing, the U.S. economy continued to move
forward. In the equity markets, a dichotomy of results relative to market
capitalization continued throughout the period. Large capitalization companies,
the type found among the S&P 500, have appreciated three times as much as small-
caps (Russell 2000) so far in 1998; they returned twice as much as small-caps
over the past 12 months.

Interest rates fell during the period, with the yield on the 30-year Treasury
Bond reaching a record low of 5.57% on June 15, 1998. With falling yields, the
longer-term fixed-income holdings performed very well in the period. It seems
that the Federal Reserve has been correct in its decision to allow interest
rates to remain unchanged in light of the prospective economic cooling influence
from Asia. Inflation was dormant throughout the period. Recently, housing and
medical costs have increased while wages continue to modestly accelerate, but
most of these pressures have been countered by falling commodity prices. It is
important to consider the inflation outlook as an indicator of the future
direction of interest rates, given the Fed's anti-inflation stance.

INVESTMENT STRATEGY

The SAM Balanced Portfolio remained diversified in five funds, representing
seven major asset classes. This broad diversification enables the Portfolio to
manage risk during periods of market volatility. Asset classes, ranging in risk
levels from cash to foreign stock, shield the Portfolio from drastic swings in
one specific area of the financial markets.

The overall investment strategy for the period was to:

 .    Increase equity exposure to 63% of assets while slightly reducing fixed-
     income exposure to 37%.
 .    Increase exposure to European holdings to take advantage of prospects for
     strength in the region.
 .    Overweight the equity portion of the portfolio in middle- and large-
     capitalization stocks.
 .    Maintain a bias towards intermediate-term bonds to take advantage of
     falling rates and provide positive risk/reward characteristics.

REVIEW OF PORTFOLIO ALLOCATIONS

We have positioned the Portfolio to take advantage of current market trends as
well as to manage overall portfolio risk levels. The Fund benefited from its
emphasis in mid- to large-cap holdings. Prior to the Asian collapse, the
Portfolio was underweighted in international stocks which aided both performance
and the overall risk of the Portfolio. Recently, we have increased exposure
overseas due to a positive outlook in Europe. We also reduced our concentration
in the very highly-valued U.S. domestic market. These moves further diversify
the assets and, in conjunction with the cash and mortgage position, should work
to manage the overall risk levels of the Balanced Portfolio given the high 
valuation levels of domestic equities.

OUTLOOK

Inflation remains weak and interest rates are low. Both the Bundesbank (Europe)
and the Federal Reserve Board (U.S.) have announced they are closely watching
inflation and maintaining a bias towards raising interest rates. If the negative
impact from Asia is less than expected, and if consumption remains strong, the
Federal Reserve may be forced to adjust rates later in the year. We believe
inflation is manageable and Chairman Greenspan has been very effective in
interest rate policy during this new paradigm. However, we believe domestic
growth will increase. Therefore, until evidence shows us weakness beyond current
forecasts, we are reluctant to extend portfolio risk on the fixed-income side of
the Fund.

We maintain our long-term positive outlook on the equity markets. The overriding
economic fundamentals provided by globalization and efficiency improvements
brought about by technological enhancements create a dynamically positive
environment for stocks. We are also bullish on foreign equities, especially
Europe, where an improving structural foundation also furnishes a positive long-
term forecast. In the same respect, we are reluctant to extend portfolio risk
much beyond current levels due to the high equity valuations.

positive backdrop for economic growth. While both fixed-income and equity
investments posted very positive results, it was not without volatility. The
crisis in the Far East sent shock waves throughout the financial markets world-
wide in the fourth quarter of 1997. The extent to which the Asian collapse
ultimately impacts U.S. and European growth is not yet known, but the
uncertainty is likely to increase market volatility until a turnaround becomes
visible.

Although there were pockets of slowing, the U.S. economy continued to move
forward. The bull market also continued as large-cap stocks drove market indices
higher.

Interest rates fell during the period, with the yield on the 30-year Treasury
Bond reaching a record low of 5.57% on June 15, 1998. With falling yields, the
longer-term fixed-income holdings performed very well in the period. It seems
the Federal Reserve has been correct in its decision to allow interest rates to
remain unchanged in light of the prospective economic cooling influence from
Asia. Inflation was dormant throughout the period. Recently, housing and medical
costs have increased while wages continue to modestly accelerate, but most of
these pressures have been countered by falling commodity prices. It is important
to consider the inflation outlook as an indicator of the future direction of
interest rates, given the Fed's anti-inflation stance.

INVESTMENT STRATEGY

The SAM Flexible Income Portfolio remained diversified in five funds,
representing eight major asset classes. This broad diversification enables the
Portfolio to manage risk during periods of market volatility. Asset classes
ranging in risk levels from cash to foreign stock shield the Portfolio from
drastic swings in one specific area of the financial markets.

The overall investment strategy for the period was to:

 .    Maintain equity exposure at 19% of assets to participate in the strength of
     the large-cap market

 .    Hold a position in cash to manage risk in a volatile market

 .    Invest 65% of the Portfolio in AAA-rated securities to reduce credit risk

 .    Maintain a bias towards intermediate-term bonds to take advantage of
     falling rates and provide positive risk/reward characteristics.

REVIEW OF PORTFOLIO ALLOCATIONS

We have positioned the Portfolio to take advantage of current market trends as
well as to manage overall risk levels. The Portfolio benefited from its
weighting in large-cap holdings, which had strong performance. As interest rates
fell in 1998, there was a rush to prepay mortgages and mortgage-backed
securities underperformed relative to other types of bonds. The overall fixed-
income structure targets the intermediate portion of the yield curve which
provides good risk/return elements. If interest rates are more stable, the
mortgage-backed securities should close the performance gap. The Portfolio has
been rebalanced during the period to keep asset levels at their target
positions. These moves further diversify the assets and should work to manage
the overall risk levels of the Flexible Income Portfolio, given our outlook for
interest rates.

OUTLOOK

Inflation remains weak and interest rates are low. Both the Bundesbank (Europe)
and the Federal Reserve Board (U.S.) have announced they are closely watching
inflation and maintaining a bias towards raising interest rates. If the negative
impact from Asia is less than expected, and if consumption remains strong, the
Federal Reserve may be forced to adjust interest rates later in the year. This
would be done to prevent the economy from overheating. We believe inflation is
manageable and Chairman Greenspan has been very effective in interest rate
policy during this new paradigm. However, we believe domestic growth will
increase. Therefore, until evidence shows us weakness beyond current forecasts,
we are reluctant to extend risk of fixed-income assets.

We maintain our long-term positive outlook on the equity markets. Although there
will always be periods of volatility, the overriding economic fundamentals
provided by globalization and efficiency improvements brought about by
technological enhancements create a dynamically positive environment for stocks.
In the same respect, we are reluctant to extend portfolio risk much beyond
current levels due to the high equity valuations. We prefer to make allocation
changes only if diversification can be maintained, and portfolio risk is not
measurably extended.

Manager, Steve Scott. Mr. Scott is a pioneer in the business of asset
allocation, with over 28 years experience. He is the architect and founder of

University, Long Beach.

PERFORMANCE REVIEW

The SAM Income Portfolio returned 8.71% (3.82% adjusted for the maximum sales
charge) for the year ended June 30, 1998. The year was characterized by market
volatility and change. During the period, the WM Group of Funds were introduced
as a result of the merger between Sierra and Composite Funds. We are pleased to
report the architectural design, fundamental policies, and management of the SAM
Portfolios continued to provide benefits to shareholders. In addition, the
continuity of asset management personnel for the SAM Portfolios remained in
place. The Fund continued to beat its benchmark index since inception, while
being managed with an effort to reduce volatility relative to single asset class
investments. Long-term results continue to provide a premium over inflation;
since inception, the Fund returned 4.82% above the rate of inflation (4.18%
adjusted for the maximum sales charge)/3/. The 30-day SEC yield on the Income
Portfolio was 5.05% as of June 30, 1998.

ECONOMIC / MARKET REVIEW

Strong economic fundamentals drove the financial markets forward in the 12-month
period ended June 30, 1998. Low unemployment, strong consumer spending, low
interest rates, and a booming housing market provided some

of the positive backdrop for economic growth. While both fixed-income and equity
investments posted very positive results, it was not without volatility. The
crisis in the Far East sent shock waves throughout the financial markets world-
wide in the fourth quarter of 1997. The extent to which the Asian collapse
ultimately impacts U.S. and European growth is not yet known, but the
uncertainty is likely to increase market volatility until a turnaround becomes
visible.

Interest rates fell during the period, with the yield on the 30-year Treasury
Bond reaching a record low of 5.57% on June 15, 1998. With falling yields, the
longer-term fixed-income holdings performed very well in the period. It seems
the Federal Reserve has been correct in its decision to allow interest rates to
remain unchanged in light of the prospective economic cooling influence from
Asia. Inflation was dormant throughout the period. Recently, housing and medical
costs have increased while wages continue to modestly accelerate, but most of
these pressures have been countered by falling commodity prices. It is important
to consider the inflation outlook as an indicator of the future direction of
interest rates, given the Fed's anti-inflation stance.

INVESTMENT STRATEGY

The SAM Income Portfolio remained diversified in four fixed-income funds,
representing six major asset classes. This broad diversification enables the
Portfolio to manage risk during periods of market volatility. Asset classes
ranging in risk levels from short-term money markets to long-term corporate
bonds shield the Portfolio from drastic swings in one specific area of the
financial markets.

The overall investment strategy for the period was to:

 .    Maintain a concentration (31%) in mortgages to boost overall yield
 .    Hold a small position in cash to manage risk in a volatile market
 .    Invest 66% of the Portfolio in AAA rated securities to reduce credit risk
 .    Maintain a bias towards intermediate-term bonds (portfolio duration of 4.1
     years) to take advantage of falling rates and provide positive risk/reward
     characteristics.

REVIEW OF PORTFOLIO ALLOCATIONS

We have positioned the Portfolio to take advantage of current market trends as
well as to manage overall portfolio risk levels. As interest rates fell in 1998,
there was a rush to prepay mortgages, and mortgage-backed securities
underperformed relative to other types of bonds. This hurt relative performance,
but mortgages should bounce back if interest rates remain stable. The position
in foreign bonds was reduced as the result of the merger of funds--this also
reduced the currency exposure in a volatile foreign market-place. The overall
fixed-income structure targets the intermediate portion of the yield curve which
provides good risk/return elements. The Portfolio has been rebalanced during the
period to keep asset levels at their target positions. These moves further
diversify the assets and should work to manage the overall risk levels of the
Income Portfolio given the outlook for interest rates.

OUTLOOK

Inflation remains weak and interest rates are low. Both the Bundesbank (Europe)
and the Federal Reserve Board (U.S.) have announced they are closely watching
inflation and maintaining a bias towards raising interest rates. If the negative
impact from Asia is less than expected, and if consumption remains strong, the
Federal Reserve may be forced to increase interest rates later in the year. This
would be done to prevent the economy from overheating. We believe inflation is
manageable and Fed Chairman Greenspan has been very effective in interest rate
policy during this new paradigm. However, we believe domestic growth will
increase. Therefore, until evidence shows us weakness beyond current forecasts,
we are reluctant to extend portfolio risk.

WM GROUP OF FUNDS
1. ORGANIZATION AND BUSINESS
 
WM Trust II (the "Trust") was organized under the laws of the Commonwealth of
Massachusetts on February 22, 1989 as a business entity commonly known as a
"Massachusetts Business Trust." The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management in-
vestment company. The Trust offers nine managed investment funds: the Short
Term High Quality Bond Fund; the California Money Fund; the Growth, Interna-
tional Growth and Emerging Growth Funds (the "Equity Funds"); the California
Municipal, California Insured Intermediate Municipal and the Florida Insured
Municipal Funds (the "Municipal Funds"); and the Target Maturity 2002 Fund
(collectively the "Funds"). WM Strategic Asset Management Portfolios ("SAM")
were organized as a Massachusetts Business Trust under the laws of the Common-
wealth of Massachusetts on March 26, 1996 and is registered under the 1940 Act,
as an open-end management investment company. SAM was established in order to
offer a range of asset allocation strategies to accommodate different invest-
ment philosophies and goals. SAM offers five portfolios: the Strategic Growth,
Conservative Growth, Balanced, Flexible Income and Income Portfolios (each a
"Portfolio" and collectively, the "Portfolios"). Prior to March 23, 1998, the
Trust was known as Sierra Trust Funds and SAM was known as Sierra Asset Manage-
ment Portfolios.
 
WM Advisors, Inc. (the "Advisor" or "WM Advisor"), a wholly-owned subsidiary of
Washington Mutual, Inc. ("Washington Mutual"), a publicly owned financial serv-
ices company, serves as investment advisor to the Trust and SAM. Sierra Invest-
ment Advisors Corporation ("Sierra Advisors") served as investment advisor to
the Trust and SAM prior to March 23, 1998. Sierra Advisors became an indirect
wholly-owned subsidiary of Washington Mutual as a result of a merger between
its parent, Great Western Financial Corporation ("GWFC"), and Washington Mutu-
al.
 
Each of the Funds, except the Target Maturity 2002 Fund, consists of four clas-
ses of shares: Class A shares, Class B shares, Class S shares and Class I
shares. The Target Maturity 2002 Fund offers only Class A shares. The Portfo-
lios offer Class A shares and Class B shares. Class A shares of the Funds and
Portfolios are subject to an initial sales charge at the time of purchase. Cer-
tain Class A shares of the Funds or Portfolios purchased without an initial
sales charge may be subject to a contingent deferred sales charge ("CDSC") if
redeemed within two years of purchase. Class B shares and Class S shares are
not subject to an initial sales charge. Class B shares and Class S shares are
generally subject to a CDSC if redeemed within five years of purchase. Class I
shares are sold exclusively to the Portfolios and are not available for direct
purchase by investors. Class I shares are not subject to an initial sales
charge or CDSC, but are subject to the annual operating expenses of the Funds.
 
Each of the Portfolios invests, within certain percentage ranges, in Class I
shares of certain of the Trust Funds and certain other mutual funds (collec-
tively, the "Underlying Funds"). Each Portfolio typically allocates its assets,
within determined percentage ranges, among the Underlying Funds. The percent-
ages reflect the extent to which each Portfolio can invest in the particular
market segment represented by each Underlying Fund, and the varying degrees of
potential investment risk and reward represented by each Portfolio's invest-
ments in those market segments and their corresponding Underlying Funds. The
Advisor may alter these percentage ranges when it deems appropriate. The assets
of each Portfolio will be allocated among the Underlying Funds in accordance
with its investment objective based on the Advisor's outlook for the economy
and the financial markets and the relative market valuations of the Underlying
Funds. In addition, in order to meet liquidity needs or for temporary defensive
purposes, each Portfolio may invest its assets directly in cash, stock or bond
index futures, options, money market securities and other short-term debt in-
struments.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts and disclosures in the financial statements.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Funds and Portfo-
lios in the preparation of their financial statements.
 
PORTFOLIO VALUATION:
 
A security that is primarily traded on a U.S. exchange (including securities
traded through the Nasdaq National Market System) is valued at the last sale
price on that exchange or, if there were no sales during the day, at the mean
of the current day's bid and asked prices. Over-the-counter securities that are
not traded through the Nasdaq National Market System and U.S. Government Secu-
rities are valued at the mean of the current day's bid and asked prices. An op-
tion is generally valued at the last sale price or, in the absence of a last
sale price, at the mean of the current day's bid and asked prices. Short term
debt securities that mature in 60 days or less are valued at amortized cost.
The value of a foreign security is determined in its national currency as of
the close
 
                                                                              89

WM GROUP OF FUNDS
of trading on the foreign exchange on which it is traded or as of 4:00 p.m.
Eastern Standard time, if that is earlier, and that value is then converted
into its U.S. dollar equivalent at the foreign exchange rate in effect at noon,
Eastern Standard time, on the day the value of the foreign security is deter-
mined. The value of a futures contract equals the unrealized gain or loss on
the contract, which is determined by marking the contract to the current set-
tlement price for a like contract acquired on the day on which the futures con-
tract is being valued. If the market makes a limit move with respect to the se-
curity or index underlying the futures contract, the futures contract will be
valued at a fair market valued as determined by or under the direction of the
Board of Trustees.
 
Debt securities of U.S. issuers (other than U.S. Government Securities and
short-term investments), including municipal securities, are valued by one or
more independent pricing services (each a "Pricing Service") retained by the
Trusts. When, in the judgement of a Pricing Service, market quotations for
these securities are readily available, they are valued at the mean between the
quoted bid prices and asked prices. Securities for which market quotations are
not readily available are valued at fair value as determined by or under the
direction of the Board of Trustees, which may rely on the assistance of one or
more Pricing Services. The procedures of each Pricing Service are reviewed pe-
riodically by the officers of the Trusts under the general supervision and re-
sponsibility of the Board of Trustees.
 
The Portfolios' investments in the Underlying Funds are valued at the net asset
value per Class I share of the respective Underlying Funds determined as of the
close of the New York Stock Exchange on each valuation date.
 
VALUATION OF THE CALIFORNIA MONEY FUND. Securities are valued on the basis of
amortized cost, which approximates market value. Amortized cost valuation in-
volves initially valuing an instrument at its cost and thereafter assuming a
constant amortization to maturity of any discount or premium, as long as the
effect of fluctuating interest rates on the market value of the instrument is
not significant. Restricted securities and certain other assets are valued by
the investment advisor under the supervision of the Board of Trustees.
 
REPURCHASE AGREEMENTS:
 
Each Fund or Portfolio may engage in repurchase agreement transactions. Under
the terms of a typical repurchase agreement, the Fund or Portfolio, through its
custodian, takes possession of an underlying debt obligation subject to an ob-
ligation of the seller to repurchase, and the Fund or Portfolio subject to ob-
ligation to resell the obligation at an agreed upon price and time, thereby de-
termining the yield during the Fund's or Portfolio's holding period. The value
of the collateral is at all times at least equal to the total amount of the re-
purchase obligation, including interest. In the event of counterparty default,
the Fund would seek to use the collateral to offset losses incurred. There is
potential loss to the Fund or Portfolio in the event the Fund or Portfolio is
delayed or prevented from exercising its right to dispose of the collateral se-
curities, including the risk of a possible decline in the value of the under-
lying securities during the period while the Fund or Portfolio seeks to assert
its rights. WM Advisors, acting under the supervision of the Board of Trustees,
reviews the value of the collateral and the credit worthiness of those banks
and dealers which each Fund or Portfolio enters into repurchase agreements.
 
FUTURES CONTRACTS:
 
Each Fund and Portfolio, except the California Money Fund, may engage in
futures transactions. The Funds or Portfolios may use futures contracts to man-
age their exposure to the stock and bond markets and to fluctuations in inter-
est rates and currency values. The underlying value of a futures contract is
incorporated within the unrealized appreciation/(depreciation) shown in the
Portfolio of Investments under the caption "Futures Contracts." This amount re-
flects each contract's exposure to the underlying instrument at June 30, 1998.
Buying futures contracts tends to increase the Fund's or Portfolio's exposure
to the underlying instrument. Selling futures contracts tends to either de-
crease the Fund's or Portfolio's exposure to the underlying instrument, or to
hedge other Fund and Portfolio investments.
 
Upon entering into a futures contract, the Fund or Portfolio is required to de-
posit with the broker an amount of cash or cash equivalents equal to a certain
percentage of the contract amount. This is known as the "initial margin." Sub-
sequent payments ("variation margin") are made or received by the Fund or Port-
folio each day, depending on the daily fluctuation of the value of the con-
tract. The daily changes in contract value are recorded as unrealized gains or
losses and the Fund or Portfolio recognizes a realized gain or loss when the
contract is closed.
 
There are several risks in connection with the use of futures contracts as a
hedging device. Futures contracts involve, to varying degrees, risk of loss in
excess of the futures variation margin reflected in the Statements of Assets
and Liabilities. The change in

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
WM GROUP OF FUNDS
the value of futures contracts primarily corresponds with the value of their
underlying instruments, which may not correlate with the change in the value of
the hedged instruments. In addition, there is the risk that the Fund or Portfo-
lio may not be able to enter into a closing transaction because of an illiquid
secondary market.
 
FOREIGN CURRENCY:
 
The books and records of the Funds and Portfolios are maintained in U.S. dol-
lars. Foreign currencies, investments and other assets and liabilities are
translated into U.S. dollars at the exchange rates prevailing at the end of the
period. Purchases and sales of investment securities, income and expenses are
translated on the respective dates of such transactions. It is not practicable
to isolate that portion of the results of operations arising as a result of
changes in the foreign exchange rates from the portion that arises from changes
in market prices of investments during the period. Accordingly, all such
changes have been reflected as realized and unrealized net gains/(losses) from
security transactions in the Statements of Operations.
 
Unrealized gains and losses, not relating to securities, which result from
changes in foreign currency exchange rates have been included in unrealized
appreciation/(depreciation) of foreign currency and other assets and liabili-
ties. Unrealized gains and losses of securities, which result from changes in
foreign currency exchange rates as well as changes in market prices of securi-
ties, have been included in unrealized appreciation/(depreciation) of securi-
ties. Net realized foreign currency gains and losses include foreign currency
gains and losses resulting from changes in exchange rates between trade date
and settlement date on investment securities transactions, gains and losses on
foreign currency transactions, and the difference between the amounts of inter-
est and dividends recorded on the books of the Funds and the amount actually
received. The portion of foreign currency gains and losses related to fluctua-
tion in exchange rates between the initial purchase trade date and subsequent
sale trade date is included in realized gain/(loss) from security transactions.
 
FORWARD FOREIGN CURRENCY CONTRACTS:
 
The Short Term High Quality Bond Fund and the Equity Funds may enter into for-
ward foreign currency contracts. Forward foreign currency contracts are agree-
ments to exchange one currency for another at a future date at a specified
price. The Funds may use forward foreign currency contracts to facilitate
transactions in foreign securities and to manage the Funds' foreign currency
exposure. The U.S. dollar market value, contract value and the foreign curren-
cies the Funds have committed to buy or sell are shown in the Portfolio of In-
vestments under the caption "Schedule of Forward Foreign Currency Contracts."
These amounts represent the aggregate exposure to each foreign currency the
Funds have acquired or hedged through forward foreign currency contracts at
June 30, 1998. Forward foreign currency contracts are reflected as both a for-
ward foreign currency contract to buy and a forward foreign currency contract
to sell. Forward foreign currency contracts to buy generally are used to ac-
quire exposure to foreign currencies, while forward foreign currency contracts
to sell are used to hedge the Funds' investments against currency fluctuations.
Also, a forward foreign currency contract to buy or sell can offset a previ-
ously acquired opposite forward foreign currency contract.
 
Forward foreign currency contracts are marked-to-market daily using foreign
currency exchange rates supplied by an independent pricing service. The change
in a contract's market value is recorded by the Funds as an unrealized gain or
loss. When the contract is closed or delivery is taken, the Funds record a re-
alized gain or loss equal to the difference between the value of the contract
at the time it was opened and the value at the time it was closed.
 
The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the Fund's securities, but it does establish a rate
of exchange that can be achieved in the future. These forward foreign currency
contracts involve market risk in excess of the unrealized
appreciation/(depreciation) of forward foreign currency contracts reflected in
the Funds' Statements of Assets and Liabilities. Although forward foreign cur-
rency contracts used for hedging purposes limit the risk of loss due to a de-
cline in the value of the hedged currency, they also limit any potential gain
that might result should the value of the currency increase. In addition, the
Funds could be exposed to risks if the counterparties to the contracts are un-
able to meet the terms of their contracts. The Fund's Advisor and/or Sub-advi-
sor will enter into forward foreign currency contracts only with parties ap-
proved by the Board of Trustees because there is a risk of loss to the Funds if
the counterparties do not complete the transaction.
 
INDEXED SECURITIES:
 
Each of the Funds and the Portfolios, except the California Money Fund, may in-
vest in indexed securities whose value is linked either directly or inversely
to changes in foreign currencies, interest rates, commodities, inflation, indi-
ces, or other reference
 
                                                                              91
<PAGE>
 
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
WM GROUP OF FUNDS
instruments. Indexed securities may be more volatile than the reference instru-
ment itself, but any loss is limited to the amount of the original investment.
 
ILLIQUID INVESTMENTS:
 
Up to 15% of the assets of each Fund and Portfolio, and up to 10% of the net
assets of the California Money Fund, may be invested in securities that are not
readily marketable, including: (1) repurchase agreements with maturities
greater than seven calendar days; (2) time deposits maturing in more than seven
calendar days; (3) to the extent a liquid secondary market does not exist for
the instruments, futures contracts and options thereon; (4) certain over-the-
counter options; (5) certain variable rate demand notes having a demand period
of more than seven days; and (6) securities, the disposition of which are re-
stricted under Federal securities laws, excluding certain Rule 144A securities,
as defined below.
 
Illiquid securities generally cannot be sold or disposed of in the ordinary
course of business within seven days at approximately the value at which the
investments have valued. This may have an adverse effect on the Fund's or Port-
folio's ability to dispose of particular illiquid securities at fair market
value and may limit the Fund's or Portfolio's ability to obtain accurate market
quotations for purposes of valuing the securities and calculating the net asset
value of shares of the Fund or Portfolio. The Funds or Portfolios may also pur-
chase securities that are not registered under the Securities Act of 1933, as
amended (the "Act"), but that can be sold to qualified institutional buyers in
accordance with Rule 144A under the Act ("Rule 144A Securities"). Rule 144A Se-
curities generally may be resold only to other qualified institutional buyers.
If a particular investment in Rule 144A Securities is not determined to be liq-
uid under the guidelines established by the Board of Trustees, that investment
will be included within the 15%/10% limitation, as applicable, on investment in
illiquid securities.
 
SECURITIES TRANSACTIONS AND INVESTMENT INCOME:
 
Securities transactions are recorded as of the trade date (the date the order
to buy or sell is executed). Realized gains and losses from securities sold are
recorded on the identified cost basis. Interest income is recorded on the ac-
crual basis and consists of interest accrued and, if applicable, discount ac-
creted less premiums amortized. Dividend income is recorded on the ex-dividend
date, except certain dividends from foreign securities are recorded as soon as
the Funds or Portfolios are informed of the ex-dividend date. Each Fund's or
Portfolio's investment income and realized and unrealized gains and losses are
allocated among the classes of that Fund or Portfolio based upon the relative
average net assets of each class.
 
Securities purchased or sold on a when-issued or delayed-delivery basis may be
settled a month or more after the trade date; interest income is not accrued
until settlement date. Each Fund or Portfolio instructs the custodian to segre-
gate assets of the Fund with a current value at least equal to the amount of
its when-issued purchase commitments.
 
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS:
 
Dividends from net investment income of the Short Term High Quality Bond Fund,
California Money Fund, Municipal Funds, Flexible Income Portfolio, Balanced
Portfolio and Income Portfolio are declared daily and paid monthly. Dividends
from the net investment income of the Conservative Growth Portfolio are de-
clared and paid quarterly. Dividends from the net investment income of the
Growth Fund and the Strategic Growth Portfolio are declared and paid
semiannually. Dividends from the net investment income of the Emerging Growth,
International Growth and the Target Maturity 2002 Funds are declared and paid
annually. Distributions of any net long-term capital gains earned by a Fund or
Portfolio are made annually. Distributions of any net short-term capital gains
earned by a Fund or Portfolio are distributed no less frequently than annually
at the discretion of the Board of Trustees. Additional distributions of net in-
vestment income and capital gains for each Fund or Portfolio may be made at the
discretion of the Board of Trustees in order to avoid the application of a 4%
non-deductible excise tax on certain undistributed amounts of ordinary income
and capital gains. Income distributions and capital gain distributions are de-
termined in accordance with income tax regulations which may differ from gener-
ally accepted accounting principles. These differences are primarily due to
differing treatments of income and gains on various investment securities held
by the Funds or Portfolios, organizational costs, dividends payable,
redesignated distributions and differing characterization of distributions made
by each Fund or Portfolio as a whole. Net investment income per share calcula-
tions in the financial highlights for the year ended June 30, 1998 for the Cal-
ifornia Money Fund, Short Term High Quality Bond Fund, California Municipal
Fund, California Insured Intermediate Municipal Fund, Florida Insured Municipal
Fund, Income Portfolio, Flexible Income Portfolio and Balanced Portfolio ex-
cludes these adjustments.

FEDERAL INCOME TAXES:
 
It is each Fund's and Portfolio's policy to qualify as a regulated investment
company by complying with the requirements of the Internal Revenue Code of
1986, as amended, applicable to regulated investment companies and by, among
other things, distributing substantially all of its taxable and tax-exempt
earnings to its shareholders. Therefore, no Federal income tax provision is re-
quired.
 
EXPENSES:
 
General expenses of the Trust are allocated to all the Funds based upon rela-
tive net assets of each Fund. General expenses of SAM are allocated to all the
Portfolios based upon relative net assets of each Portfolio. Operating expenses
directly attributable to a class of shares are charged to the operations of
that class of shares. Expenses of each Fund or Portfolio not directly attribut-
able to the operations of any class of shares are prorated among the classes to
which the expenses relate based on the relative average net assets of each
class of shares.
 
OTHER:
 
The Municipal Funds and the Short Term High Quality Bond Fund may purchase
floating rate, inverse floating rate and variable rate obligations, including
municipal securities and participation interests therein. Floating rate obliga-
tions have an interest rate that changes whenever there is a change in the ex-
ternal interest rate, while variable rate obligations provide for a specified
periodic adjustment in the interest rate. The interest rate on an inverse
floating rate obligation (an "inverse floater") can be expected to move in the
opposite direction from the market rate of interest to which the inverse
floater is indexed. The Short Term High Quality Bond Fund may also purchase
mortgage-backed securities that are floating rate, inverse floating rate and
variable rate obligations. Although variable rate notes are frequently not
rated by credit rating agencies, unrated notes purchased by the Fund will be of
comparable quality at the time of purchase to rated instruments that may be
purchased by the Fund, as determined by the Advisor. The absence of such an ac-
tive secondary market, however, could make it difficult for the Fund to dispose
of a particular variable rate demand note in the event the issuer of the note
defaulted on its payment obligations, and the Fund could, for this or other

An inverse floater may be considered to be leveraged to the extent that its in-
terest rate varies by a magnitude that exceeds the magnitude of the change in
the index rate of interest. The higher degree of leverage inherent in inverse
floaters is associated with greater volatility in their market values. Accord-
ingly, the duration of an inverse floater may exceed its stated final maturity.

4. TRUSTEES' FEES
 
On March 20, 1998, the board of trustees of the Trust and SAM combined with the
board of trustees of the WM Group of Funds.
 
No director, officer or employee of Washington Mutual or its subsidiaries re-
ceives any compensation from the Trust or SAM for serving as an officer or
Trustee of the Trust or SAM. The Trust, together with other Trusts advised by
WM Advisors, Inc., pays each Trustee who is not a director, officer or employee
of Washington Mutual or its subsidiaries, $18,000 per annum plus $3,000 per
board meeting attended in person and $1,000 per board meeting attended by tele-
phone and reimbursement for travel and out-of-pocket expenses. The Chairman of
each committee receives $500 per committee meeting attended.
 
Pursuant to an exemptive order granted by the Securities and Exchange Commis-
sion (the "SEC"), the Trust's eligible Trustees may participate in a deferred
compensation plan (the "Plan") which may be terminated at any time. Under the
Plan, Trustees may elect to defer receipt of all or a portion of their fees
which, in accordance with the Plan, are invested in mutual fund shares. Upon
termination of the Plan, Trustees that have deferred compensation accounts un-
der the Plan will be paid benefits no later than the time the payments would
otherwise have been made without regard to such termination. All benefits pro-
vided under these Plans are funded and any payments to Plan participants are
paid solely out of the Trust's assets.
 
5. DISTRIBUTION PLANS
 
As of March 23, 1998 WM Funds Distributor, Inc. (the "Distributor"), a regis-
tered broker-dealer and indirect wholly-owned subsidiary of Washington Mutual,
serves as distributor for Class A, B and S shares of the Funds. Prior to March
23, 1998, WM Fund Services, Inc. ("WM Services"), formerly Sierra Investment
Services Corporation, a registered investment company and broker-dealer, served
as distributor. The Distributor and WM Services received $58,233 and $121,932,
respectively, representing commissions (front-end sales charges) on Class A
shares. In addition, the Distributor and WM Services received $653,684 and
$1,497,900 respectively, representing CDSC fees from Class B and S shares. On
May 1, 1998 Great Western Financial Securities Corporation ("GW Securities"), a
registered broker-dealer, merged with WM Financial Services, Inc. ("WM Securi-
ties"). GW Securities and WM Securities received $718,887 representing commis-
sions on Class A shares. In addition, GW Securities and WM Securities received
$654,594 representing CDSC fees from Class B and S shares.
 
Each of the Funds has adopted three distribution plans, pursuant to Rule 12b-1
under the 1940 Act, applicable to Class A, Class B and Class S shares of the
Fund (each, a "Rule 12b-1 Plan"), respectively. There are no 12b-1 Plans appli-
cable to Class I shares of the Funds. Under the applicable Rule 12b-1 Plans,
the Distributor receives a service fee at an annual rate of 0.25% of the aver-
age daily net assets of each class. In addition, the Distributor is paid a fee
as compensation in connection with the offering and sale of Class B and Class S
shares at an annual rate of 0.75% of the average daily net assets of such
shares. These fees may be used to cover the expenses of the Distributor primar-
ily intended to result in the sale of such shares, including payments to the
Distributor's representatives or others for selling shares. Because the Dis-
tributor may retain any amount of its fee that is not so expended, the Rule
12b-1 Plans are characterized by the SEC as "compensation-type" plans. The
service fee is paid by the Fund to the Distributor, which in turn pays a por-
tion of the service fee to broker/dealers that provide services, such as ac-
cepting telephone inquiries and transaction requests and processing correspon-
dences, new account applications and subsequent purchases by check for the
shareholders. Under their terms, each of the Class A Plan, Class B Plan and
Class S Plan shall remain in effect from year to year, provided such continu-
ance is approved annually by vote of the Board of Trustees, including a major-
ity of those Trustees who are not "interested persons" of the Trust, as defined
in the 1940 Act, and who have no direct or indirect financial interest in the
operations of such distribution plans, or any agreements related to such plans,
respectively.
 
Each of the Portfolios has adopted two distribution plans, pursuant to Rule
12b-1 under the 1940 Act, one for the Class A shares ("Class A Plan") and one
for the Class B shares ("Class B Plan"). Under the Class A and Class B Plans,
the Distributor is to be paid a shareholder service fee at an annual rate of
0.25% of the average daily net assets of each Classes shares. In addition, un-
der the Class B Plan, the Distributor is to be paid an annual distribution fee
of up to 0.75% of the average daily net assets of the Class B shares of each
Portfolio for activities primarily intended to result in the sale of Class B
shares of the Portfolios.

8. ORGANIZATION COSTS
 
Expenses incurred in connection with the organization of the Funds, including
the fees and expenses of registering and qualifying its shares for distribution
under Federal and state securities regulations, are being amortized on a
straight-line basis over a period of five years from commencement of operations
of each Fund, respectively. In the event any of the initial shares of a Fund
are redeemed by any holder thereof during the amortization period, the proceeds
of such redemptions will be reduced by an amount equal to the pro-rata portion
of unamortized deferred organizational expenses in the same proportion as the
number of shares being redeemed bears to the number of initial shares of such
Fund outstanding at the time of such redemption.

10. GEOGRAPHIC AND INDUSTRY CONCENTRATION AND RISK FACTORS
 
There are certain risks arising from the California Money, California Municipal
and California Insured Intermediate Municipal Funds' investments in California
municipal securities. The California Money, California Municipal and California
Insured Intermediate Municipal Funds' are more susceptible to factors adversely
affecting issuers of California municipal securities than is a municipal bond
fund that is not concentrated in these issuers to the same extent. Uncertain
economic conditions or governmental developments may affect the ability of Cal-
ifornia municipal securities issuers to meet their financial obligations.
 
The Florida Insured Municipal Fund primarily invests in debt obligations issued
by the State of Florida and its political subdivisions, agencies and public au-
thorities to obtain funds for various public purposes. The Florida Insured Mu-
nicipal Fund is more susceptible to factors adversely affecting issuers of
Florida municipal securities than is a municipal bond fund that is not concen-
trated in these issuers to the same extent. Uncertain economic conditions or
governmental developments may affect the ability of Florida municipal securi-
ties issuers to meet their financial obligations.
 
The Short Term High Quality Bond Fund and the Equity Funds invest in securities
of foreign companies and foreign governments. There are additional certain
risks involved in investing in foreign securities. These risks include those
resulting from adverse political and economic developments and the possible im-
position of currency exchange restrictions or other foreign laws or restric-
tions.
 
Investing in the Underlying Funds through the Portfolios involves certain addi-
tional expenses and tax results that would not be present in a direct invest-
ment in the Underlying Funds. For example, under certain circumstances, an Un-
derlying Fund may determine to make payment of a redemption request by a Port-
folio wholly or partly by a distribution in kind of securities from its Portfo-
lio, instead of cash, in accordance with the rules of the SEC. In such cases,
the Portfolios may hold securities distributed by an Underlying Fund until the
Advisor determines that it is appropriate to dispose of such securities.
 
Certain Underlying Funds may invest a portion of their assets in foreign secu-
rities; enter into forward foreign currency transactions; lend their portfolio
securities; enter into stock index, interest rate and currency futures con-
tracts, and options on such contracts; enter into interest rate swaps or pur-
chase or sell interest rate caps or floors; engage in other types of options
transactions; make short sales; purchase zero coupon and payment-in-kind bonds;
engage in repurchase or reverse repurchase agreements; purchase and sell "when-
issued" securities and engage in "delayed-delivery" transactions; and engage in
various other investment practices, each with inherent risks.
 
The Strategic Growth Portfolio can invest as much as 50% of its total assets in
the Growth Fund, 50% of its total assets in the Emerging Growth Fund and 25% of
its total assets in the High Yield Fund, each of which may invest as much as
35% (100% in the case of the High Yield Fund) of its total assets in lower-
rated bonds. Securities rated below investment grade generally involve greater
price volatility and risk of principal and income and may be less liquid than
higher rated securities.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
WM GROUP OF FUNDS
Certain Portfolios may invest as much as 50% of their total assets in the
Growth or Emerging Growth Funds, each of which may invest up to 25% of its to-
tal assets in foreign equity securities and as much as 5% of its total assets
in securities in developing or emerging markets countries. Certain Portfolios
invest as much as 50% of their total assets in the International Growth Fund,
which invests primarily in foreign equity securities, and may invest as much as
30% of its total assets in securities in developing or emerging market coun-
tries. These investments will subject such Portfolios to risks associated with
investing in foreign securities, including those resulting from adverse politi-
cal and economic developments and the possible imposition of currency exchange
restrictions or other foreign laws or restrictions.
 
The Officers and Trustees, the Advisor, the Distributor and Transfer Agent of
the Portfolios serve in the same capacity for the Underlying Funds. Conflicts
may arise as theses persons and companies seek to fulfill their fiduciary re-
sponsibilities to both the Portfolios and the Underlying Funds.
 
From time to time, one or more of the Underlying Funds used for investment by a
Portfolio may experience relatively large investments or redemptions due to
reallocations or rebalancings by the Portfolios. These transactions will affect
the Underlying Funds, since the Underlying Funds that experience redemptions as
a result of the reallocations or rebalancings may have to sell portfolio secu-
rities and the Underlying Funds that receive additional cash will have to in-
vest such cash. While it is impossible to predict the overall impact of these
transactions over time, there could be adverse effects on portfolio management
to the extent that the Underlying Funds may be required to sell securities or
invest cash at times when they would not otherwise do so. These transactions
could also have tax consequences if sales of securities resulted in gains and
could also increase transactions costs. The Advisor is committed to minimizing
such impact on the Funds to the extent it is consistent with pursuing the in-
vestment objectives of the Portfolios. The Advisor may nevertheless face con-
flicts in fulfilling its responsibilities. The Advisor will, at all times, mon-
itor the impact on the Funds of transactions by the Portfolios.
 
11. REORGANIZATION
 
On January 30, 1998, the Short Term High Quality Bond Fund acquired the assets
and certain liabilities of the Short Term Global Government Fund, in a taxable
exchange for shares of the Short Term High Quality Bond Fund, pursuant to a
plan of reorganization approved by the Short Term Global Government Fund's
shareholders. Total shares issued by, the value of the shares issued by, and
the total net assets of the Short Term High Quality Bond Fund were 15,906,268,
$37,061,604 and $14,588,984, respectively. The total net assets of the Short
Term Global Government Fund were $37,061,604. The total net assets of the Short
Term High Quality Bond Fund after the acquisition were $51,650,588.

 REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE TRUSTEES AND SHAREHOLDERS OF WM TRUST II AND WM STRATEGIC ASSET
MANAGEMENT PORTFOLIOS
 
In our opinion, the accompanying statements of assets and liabilities, includ-
ing the portfolios of investments, and the related statements of operations and
of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of each of the nine funds constitut-
ing the WM Trust II and five portfolios constituting WM Strategic Asset Manage-
ment Portfolios, collectively the "Trusts", at June 30, 1998, and the results
of each of their operations for the year then ended, the changes in each of
their net assets and the financial highlights of each of the funds and portfo-
lios for the periods indicated, in conformity with generally accepted account-
ing principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Trusts'
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which re-
quire that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and dis-
closures in the financial statements, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall finan-
cial statement presentation. We believe that our audits, which included confir-
mation of securities at June 30, 1998 by correspondence with the custodian and
brokers, provide a reasonable basis for the opinion expressed above.
