</TABLE>
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing
to 0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

growth funds for Class A and 25 of 884 funds for Class B.
   Despite being down for the quarter -1.17% for Class A shares and -1.34% for
Class B shares, not including the effects of sales charges, the Fund delivered
17.11% for Class A shares and 16.49% for Class B shares, not including the
effect of sales charges for the last six months. The average growth fund went
1.85% for the quarter and 15.11% for the half year. But over longer time periods
I'm more optimistic.
   Our performance, the Fund's volatility, and the fact that we are often out of
step with the rest of the market are due to one thing: eclectic stock picking.
 
   Because its good performance was discovered, SAFECO Growth experienced
tremendous asset growth and a drop in its expense ratio. Assets grew from $262
million at June 30, 1997, to $1.6 billion at June 30, 1998.
   Because of the cash inflow, I bought some larger caps, notably: Avon, Green
Tree Financial, American Home Products, Philip Morris and Kimberly-Clark. The
advantage of investing in these larger companies is that I can acquire enough
stock to make a difference in the Fund's performance. Additionally, the money
goes right to work and is readily accessible when more intriguing opportunities
arise.

                      REPORT FROM THE GROWTH FUND MANAGER
 
   Green Tree, a manufactured housing financier that the Fund has
owned in the past, contributed tremendously to the Fund's success so
far in 1998. Its stock fell on an accounting controversy and we
acquired it on the cheap. Then, due to an agreement to merge with Conseco, it
climbed to be one of last quarter's top-performers on the New York Stock
Exchange.
   We started buying Avon after its price fell on near-term earnings concerns.
Its long-term focus on cost cutting gives it a great outlook for earnings
growth. Indeed, year to date the stock is up 27% versus the S&P's 18%.
   We bought American Home Products when its stock lost weight on a problem with
its diet drugs. Over the last six months, the stock gained 35% versus the S&P
500's 18%. A practiced acquirer, American Home recently announced a merger with
Monsanto that further solidifies its scientific nature and greatly enhances its
long-term growth prospects.

 NET ASSET CAPITALIZATION WEIGHTINGS

Large:   27% ($4 Bil. and above)
Medium:  19% ($1 Bil. - $4 Bil.)
Small:   54% (Less than $1 Bil.)
 
   I like larger caps only when I smell value in them, and that usually arises
from a controversy. My preferred stocks continue to be those that are
undiscovered with ample room to appreciate. My current favorites include: Family
Golf (a consolidator of driving range facilities that has essentially acquired
all its major competition), Dura Pharmaceutical (a smaller pharmaceutical that
has created a niche in respiratory drugs), MICROS Systems (a point of sale
inventory systems provider that is simultaneously cutting costs and expanding
its product line and customer base), United Stationers (the largest player in
the consistent business of office product distribution) and Corrections Corp
(the largest private operator of prisons).
   As your fund manager, I am working to invest creatively, keep up our good
results, be thankful when things go well, and remember that nothing lasts
forever.

The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived  from the Funds original class of shares
and reflects the maximum 4.5% sales charge for  Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated  to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and  Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past  performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

                      REPORT FROM THE EQUITY FUND MANAGER
 
companies, which clearly underperformed the S&P 500.
   The Fund lagged the S&P 500 because we have a lower price/ earnings ratio
(P/E). Within the S&P 500, higher P/E stocks outperformed lower P/E stocks.
   Even though our orientation to value caused the Fund to lag the index, I
really like the overall strength of our lower-priced, aiming-for-predictable
portfolio. Admission standards for stocks in the Equity Fund are stringent
enough that I have confidence in our holdings, especially in the event of a
market downturn.
   Two new names were admitted to the Fund during the quarter Travelers and
Washington Mutual. I intend to hold both for a long time, as both of them are
quality acquirers in consolidating industries. Purchased at slightly less than
13 times its estimated 1999 earnings in a market that is trading at over 21
times the 1999 earnings, Washington Mutual is a sound way for us to participate
in the consolidation of the savings and loan industry.
   We paid 15 times Traveler's expected earnings estimate. I bought it after it
announced it would merge with Citicorp to form CitiGroup. In addition to
attractive near-term value, Travelers has the long-term potential

to cross-sell its insurance and investor services to Citicorp's
banking and credit clientele and vice versa for Citicorp.
   I let go of First Data because I fear that consolidation of the
financial service sector will hurt their core business--the processing of
merchant transactions. Other positions eliminated during the most recent quarter
include Columbia/HCA, PacifiCare Health Systems, and Electronic Data Systems,
which I did to further improve the quality of our holdings and to decrease the
volatility of our returns.
   While my intent is to build a portfolio of companies that I can comfortably
hold through thick and thin, I am sensitive to the fact that valuation matters.
Hence, I sold the fourth position, Houston, because it had reached our target
price.

   I also sold part of Microsoft, Wal-Mart, General Electric, DuPont, PepsiCo
and American Home Products when these companies began to look expensive. On the
flip side, I added to our holdings in Hewlett-Packard, Dover, Fannie Mae, Intel
and Bell Atlantic when their prices looked right.
   The theme to all this, which is evidenced in our portfolio and in our low
turnover, is that we are long-term investors, holding above-average companies in
more predictable industries. For example, there are currently no technical or
cyclical companies in our top ten.
   The market is expensive, which has made me a very cost-and quality-conscious
manager. I am making a concerted effort not to pay too much for a stock in a
market that seems overpriced, or reach too far in a market that seems
precipitous. I am holding companies I want to own--companies whose long-term
outlooks give me solace.

   SAFECO Income Fund continues to perform very well with total returns
that exceed its peer funds for the quarter, six months and year ending
June 30, 1998.
   In the second quarter, six and 12 months just ended, the Fund returned .47%,
11.78% and 24.36% for Class A shares and .29%, 11.85% and 24.06% for Class B
shares, not including the effects of sales charges, respectively. That exceeds
- -.97%, 9.13% and 20.95%, the comparable returns for the average equity-income
fund reported by Lipper Analytical Services, Inc., for the same three periods.
The S&P 500 returned 3.30%, 17.70% and 30.15%, also for the same three periods.

The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived  from the Funds original class of shares
and reflects the maximum 4.5% sales charge for  Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated  to reflect Rule 12b-1 fees prior to September 30, 1996  (initial
public offering date of Class A and  Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past  performance is not predictive of future results. Principal value
may fluctuate so that shares,  when redeemed, may be worth more or less than
their original cost.

that the Fund's volatility is 71% percent that of the S&P 500. Over the same
three-year period, the Fund's average annual total return (25.71%) has been 85%
that of S&P's (30.19%). In short, Income Fund shareholders have gotten 85% of
the S&P 500's return for 71% of the risk.
   I cut back American Home Products, formerly the largest holding of the Fund,
to a normal position size, 2.5% of net assets. Having appreciated 42% in nine
months, the stock's upside potential became less compelling.
   Conversely, I increased two of our holdings, CCA Prison Real Estate
Investment Trust (REIT) and Chancellor Media convertible preferred, to 5.1% and
5.3%, respectively, of net assets when they declined on reasons unrelated to
their business prospects. I further increased our stake in radio broadcasting,
an industry on which I am very positive, by buying Emmis Broadcasting on a
secondary offering. It was very cheap relative to its peers.
   I established several other new positions. I bought Hewlett-Packard and SCI
Systems

                      REPORT FROM THE INCOME FUND MANAGER
 
convertible debentures when the stocks declined in sympathy with the tech sector
to prices that I thought represented excellent value. I purchased Suburban
Lodges because I judged the stock to have very little downside risk and
tremendous upside potential. Finally, I established a new position in Newell
Financial convertible preferred because the stock looked cheap relative to its
three-year growth prospects and to other companies in the housewares sector.
   Five holdings were eliminated from the portfolio. I sold Home Depot
convertible and U.S. Bancorp stock for attractive gains after both companies'
stock appreciated to lofty valuation levels. I sold Adaptec, after having
purchased it just last quarter, because of deteriorating prospects for the
company. I sold First Data and Northwest Natural Gas for similar
reasons--lackluster prospects.
   As of quarter end, the Income Fund was composed of 66% common stocks, 18%
preferred stock, 10% convertible bonds and 6% cash equivalents. Of the common
stock portion, 7% is invested in Real Estate Investment Trust (REIT) stocks.
EDGAR REPRESENTATION OF DATA POINTS USED IN PRINTED GRAPHIC
 
    NET ASSET CAPITALIZATION WEIGHTINGS
        AS A PERCENT OF NET ASSETS
 
Large:               42% ($4 Bil. and above)
Medium:               8% ($1 Bil. - $4 Bil.)
Small:               16% (Less than $1 Bil.)
Preferred Stocks:    18%
Corporate Bonds:     10%
Cash and Other:       6%
 
   On the whole, I would say that the portfolio is more defensively positioned
now than it was six months ago, or any other time during my tenure as portfolio
manager. I continue to believe that there is very little margin of safety built
into current stock market valuations. I think the primary source of risk to
these valuations is earnings, more specifically, disappointing earnings at some
of the large multinationals in the S&P 500.
   The fund is still positioned to deliver a yield that is higher than the S&P
500. We are invested with exposure to domestic companies and to small- and
mid-capitalization stocks and convertibles, areas that I believe will tend to
outperform over the next 12 months or so. As always, I continue to focus on
investing in higher quality companies with growing revenues and earnings as long
as they are selling at reasonable prices.

* The Funds inception was February 7, 1991.  Graph and average annual return
comparison begins February 28, 1991.
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Funds original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

26.80% for the one year.
   The reasons for our underperformance involve the nature of our investing
universe. Tech stocks and Asia-affected stocks did poorly, and the Northwest
economy has more tech stocks and roughly twice the Asian exposure of other
regions. Further exacerbating the situation is our ownership of a lot of small-
cap stocks, which also did poorly. (In the latest quarter, the Russell 2000
Index, which has a median market cap of $395 million versus the Fund's $516
million, tumbled 4.6%.)
   Innova, a small, communications tech stock affected by Asia cascaded 67% over
the quarter as the yen declined, advancing the Japanese's competitive position.
   Both Lattice Semiconductor and Sequent Computer suffered substantial declines
for the quarter (45% and 34%, respectively) as Asian orders dwindled. Boeing's
postponement of a major order further hurt Sequent. Boeing was down 9% for the
six months, but appears to be overcoming the problems created by their attempt
to increase production 140%--a difficult task for any management.
   Seattle FilmWorks share price fell, so I bought more. I anticipate better
earnings and exciting new product developments going

                     REPORT FROM THE NORTHWEST FUND MANAGER
 
forward. I am not going to sell these hard hit stocks. I think they represent a
lot of potential. Eagle Hardware did. We held it through hardware's hard times
last year, and in the last three months, it gained 31%.
   We've also benefited from researching, visiting and buying Morrison Knudsen
before Wall Street discovered it. Rescued from chapter 11, given a clean slate
and honest management, this construction engineering company is putting together
positive earnings.
   Physio-Control (defibrillators) was up over 50% in the last quarter on the
news that it would be purchased by Medtronic. Microsoft did well, as usual, up
68% in the last six months. Starbuck's stock continues to perk, as it expands in
Europe, and Costco is doing well adding new services.

   With lumber near the bottom of the cycle, I took a full position in
Weyerhaeuser. The company represented the best value in the group and has a new
CEO, from whom we expect good things.
   I also bought Ambassadors International, a Spokane-based specialty travel
company, and Cavanaugh, a Spokane-based hotel chain. In addition, I participated
in the IPO of Washington Banking. My strategy here is to take small positions of
small banks in healthy economies.
   In summary, I feel pretty shaken by the last six months, but whole. I like
the valuations of the 38 stocks that comprise the Fund and their outlooks. Our
outlook for the Northwest Economy is that it will slow, but continue to
outperform the nation. We don't know what toll Asia will take, so we have
limited our exposure there. I expect technology to become a bigger component of
our economy and offer more consistent growth as the sector matures. It also
seems to me, that smaller undervalued companies are bound to return to favor and
that good things come to those who wait.

                              SAFECO BALANCED FUND
                                 June 30, 1998

- --------------------------------------------------------------------------------
 
   For the quarter, year-to-date and 12-month periods ended June 30, the
Balanced Fund returned -1.2%, 6.1% and 12.7% for Class A shares and -1.4%, 5.7%
and 11.8% for Class B shares, not including the effects of sales charges. This
compares unfavorably to the average balanced fund, which returned 1.2%, 8.9% and
17.6% for the same periods, according to Lipper Analytical Services, Inc. A
composite 60%/40% of the S&P 500 and the Lehman Government/Corporate Index
returned 3.02%, 12.29% and 22.60%.
   There are three main reasons the SAFECO Balanced Fund lagged other balanced
mutual funds and the composite index. All of them have to do with our
conservatism.                [PHOTO OF REX BENTLEY]

* Graph and average annual return comparison begins January 31, 1996,
inception date of the fund.
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

                     REPORT FROM THE BALANCED FUND MANAGERS
 
   In a period when the ideal asset mix was growth stocks, long bonds, and as
much equity exposure as possible, we owned value stocks, intermediate bonds and
had a mid-range equity allocation. While our strategy has underperformed
recently, there is ample historical evidence that our equity and fixed income
strategies produce better risk-adjusted returns over time, and we are confident
they will again.
 
   The biggest factor working against us was our equity investment style, which
favors low price/earnings ratios (P/E), high dividends and low price-to-book
value. As most of the S&P 500's gains over the past year have come from high P/E
stocks, funds using a growth style have produced much better

returns than our value style has delivered. (The report on the SAFECO U.S. Value
Fund on page 43 provides a detailed discussion of how value stocks have lagged
stocks with growth characteristics by a wide margin.)
 
   The second factor that worked against the relative returns for the Balanced
Fund is our fixed-income strategy. While we favor intermediate maturities, long
bonds provided considerably higher returns over the past quarter and year as
rates declined.

       NET ASSET CAPITALIZATION WEIGHTINGS
           AS A PERCENT OF NET ASSETS
 
COMMON STOCKS
Large:                       50% ($4 Bil. and above)
Medium:                       8% ($1 Bil. - $4 Bil.)
Small:                        1% (Less than $1 Bil.)
Corporate Bonds:             12%
Asset Backed Securities:      6%
U.S. Government Securities:  20%
Cash and Other:               3%
 
   Our allocation to stocks of just below 60% (in an allowable range of 50% to
70% equities) also hurt us. While a more aggressive equity weighting would have
improved our relative returns, we are comfortable with this asset mix in a stock
market that is selling at 21 times its expected earnings.
   During the quarter, additions to the portfolio included: New York Times
Company, Century Telephone Enterprises, KeyCorp, Halliburton, and Dean Foods. We
deleted positions in Harsco, First Data Corp., Baxter International, and
Bestfoods.
   The swap out of Bestfoods and into Dean Foods is a good example of value
investing. While both companies are expected to grow around 12% over the long-
term, Dean Foods sells at a P/E of less than 18 times next year's earnings,
while Bestfoods' P/E was just over 26 times when we sold it. By purchasing Dean
Foods, we get the same expected growth rate at a 30% lower P/E.
   In the fixed-income portion of the portfolio, we sold some holdings in the
very rich 10-year maturity sector of the yield curve and bought a higher
yielding combination of securities with maturities of two and 20 years. The swap
was essentially duration neutral.
   We concentrated our holdings in issues insulated from the problems in Asia,
such as U.S. Treasuries and agency mortgage-backed securities and notes. We also
moved into and out of the investment-grade corporate bonds as this sector
cheapened, richened, and cheapened again relative to U.S. Treasuries.

   At quarter end, the fixed-income assets we held were 54% in U.S. Treasury
obligations, 31% in high-grade corporate bonds, 13% in mortgage-backed
securities, and 2% in AAA asset-backed securities. The effective duration was
5.6 years on June 30, 1998, slightly longer than the duration of the Lehman
Brothers Government/Corporate Bond Index at 5.5 years.

* Graph and average annual return comparison begins January 31, 1996,
inception date of the fund.
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

earnings. Stocks quoted in Leading Consumer Franchises also did quite well.
Nestle (3.3% of net assets) announced sales growth while analysts predict
substantial cost savings from recent acquisitions.
   At 20% of net assets, Banking and Finance currently comprise our largest
sector. Good prospects for continued economic recovery buoyed by low interest
rates and expectations for further consolidation contributed to a run up for
European Financial stocks. Within the portfolio, Banco de Santander, which
announced it would acquire another Spanish bank, was a standout.
   Stocks in Healthcare Needs had a good first quarter led by Zeneca, which
posted significant increases in profits and sales. Glaxo Wellcome advanced and
then retreated on the news that it would and then would not merge with
SmithKline Beecham.
   Most of the portfolio's negative contributions came from stocks either quoted
in or with significant earnings' exposure to Asia.

                REPORT FROM THE INTERNATIONAL STOCK FUND MANAGER
 
added value over the year to date. We maintain hedges against the Japanese yen,
the German deutschemark, the Swiss franc and the British pound.
   Our largest concentration of equities (30.20% of net assets) is in the UK.
Stocks there benefited by the lowest interest rate levels in more than 30 years.
The Bank of England gave the market a jolt at the beginning of June with a
surprise 25 basis points increase in rates. Also of interest, in the UK the
mid-cap sector continued its outperformance of large-cap stocks.
   Low bond yields, the receding Asian crisis, a positive Wall Street backdrop,
surging liquidity as International managers cutback their allocations to Asia,
satisfactory corporate earnings and the prospect of further consolidation all
played a part in pushing the Continental European markets higher. Italy and
Spain performed especially well. Though interest-rate fears shadowed the start
of the second quarter, by May the continental markets were strong again.
   Asian markets rebounded during February to have the majority of the year's
gains erased during April. Hong Kong was very weak in the second quarter with
two-thirds of announced company earnings coming in below expectations. Asian
markets remained on the downward spiral during June, dragged down by weaker
currencies, falling property prices, and an ever-rising number of non-performing
loans in the financial sector.
   Sentiment regarding Japan remains somewhat negative, following uninspiring
Japanese government packages and the yen's continued weakening against the
dollar. However, we see signs of reform on the margins. Share buybacks, mergers
and acquisitions, together with corporate restructuring, gives us cause for
optimism about Japan on a company-by-company basis, and we currently have 13.4%
of net assets invested there. We will remain highly selective in our approach to
the rest of Asia.
   Our focus remains primarily on European-quoted companies, particularly in the
telecom, pharmaceutical and financial sectors. We believe that in the short-term
these companies are best poised to outperform.
   We will continue to maintain a fully invested portfolio using a fundamental,
value-oriented prospective.

* Graph and average annual return comparison begins January 31, 1996,
inception date of the fund.
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

   The six and 12-month outperformance is due to large gains in numerous
individual stocks. In other words, the results are attributable to stock
selection. As of June 30, three of our stocks-- Penederm, Platinum Software, and
Ovid Technologies--were up 100% or better on a year-to-date basis. Each of these
was purchased in a large enough weighting to contribute meaningfully to the
return of the Fund. Many of our other picks had double-digit gains.
   Penederm, already our largest position, increased substantially on the news
it would be purchased by Mylan. Platinum Software is simply a company with a
good product (enterprise software) that overcame poor management. Ovid, an
internet stock that aggregates and sells access to published medical
information, remains one of my favorites. The company is already profitable
building a great franchise and positioning itself as the gatekeeper to medical
information retrieval. Stage Stores, a retailer making cosmopolitan margins in
lower cost locations, also held its place in our top ten.

                REPORT FROM THE SMALL COMPANY STOCK FUND MANAGER
 
   Litchfield Financial is new to our top holdings and has consistent earnings
growth. It is a financial services company that specializes in rural land and
time-share loans. I increase our holdings with them each time the price moves
into the range of what I think represents good value.
   Chart Industries manufactures gas containment tanks and related equipment. It
has currently come under some pressure, but has earnings growth and free cash
flow that look good for the long term. Furthermore, Chart's acquisition of a
similar UK company should soon add to earnings in what is already a profitable
business.

Mid-Cap:          3% ($1 billion - $4 billion)
Small-Cap:       90% (under $1 billion)

  Medium:        19% ($250 - $750 million)
  Small:         71% (under $250 million)
Cash and Other:   7%
 
   We witnessed a full 10% correction in the Russell 2000 Index from April 21st
to late June, something the large cap universe did not have to
endure.
   Looking at the rest of 1998, the small cap sector is very well
positioned compared to large caps. As a group they are cheaper on
most valuation measures, and I believe they can grow earnings at a
faster rate than the S&P 500.
   The Fund will remain invested in broadly diversified small cap stocks that we
believe are good businesses at good values relative to their earnings prospects,
or cheap by some other yardstick. It will also remain broadly diversified across
a range of industry sectors.

   It seemed that the more "value" orientation a Fund had, the worse the fund
performed in the second quarter compared to the S&P 500 Index. Indeed, the Value
Fund lagged the S&P 500 by a wide margin, returning -3.79% for Class A shares
and -3.95% for Class B shares, not including the effects of sales charges, for
the quarter ended June 30, 1998, compared to the S&P 500's return of 3.30%.
                             [PHOTO OF REX BENTLEY]
   For the six month period ended June 30, 1998, the Fund returned 7.08% for
Class A shares and 6.62% for Class B shares; not including the effects of sales
charges, compared to the S&P 500's return of 17.70%.
   The biggest factor working against us over the last quarter and year has been

* The Funds inception was April 30, 1997.  Graph and total return comparison
begins April 30, 1997, inception date of the fund.
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

investment style. Because most of the S&P 500's gains have of late come from
"growth" stocks, funds using a growth style produced much the better returns.
While our strategy has underperformed recently, there is ample historical
evidence that value investing produces better risk-adjusted returns over time
and we are confident that they will again.
   There are three main measures used to determine if a portfolio is employing a
value style. They are: 1) a price/earnings ratio (P/E) lower than the market, 2)
a current yield higher than the market, 3) a lower than market price-to-book
value. Here's how the U.S. Value holdings and the S&P 500 differed based on
those attributes on June 30: the Fund's holdings had a P/E of 16.4 while the
market was priced at 22.1 times 1999 earnings estimates. The yield on the Fund's
holdings was 2.1% versus the index's 1.3%. The Funds holdings had an average
price to book ratio of 3.3% versus 4.3% for the S&P 500.

three, six and 12-month periods. For the one year, S&P stocks with P/Es less
than 22 returned 15.3% while those with P/Es greater than 22 posted 46.4%
returns. Stocks yielding above the S&P 500 average returned 13.7%. Stocks with
lower than market price to book ratios returned just 13.6%.
   It is somewhat heartening to note that even though stocks with high P/Es have
been the market's best performers, our selection of value stocks out-performed
the value members of the S&P 500.
   It seems, in general, that the higher the P/E the better a stock has
performed. This has led some market pundits to quip that valuations no longer
matter. We continue to believe that valuation, or price, does matter, and at
some point it will become extremely important. While we don't know when that
time will come, we believe it will be soon.
   During the quarter, additions to the portfolio included New York Times
Company, Century Telephone Enterprises, KeyCorp, Halliburton, and Dean Foods. We
deleted positions in Harsco, First Data Corp., Baxter International, and
Bestfoods.
   The swap out of Bestfoods and into Dean Foods is a good example of value
investing. While both companies are expected to grow around 12% over the
long-term, Dean Foods sells at a P/E of less than 18 times next year's earnings,
while Bestfoods' P/E was just over 26 times when we sold it. By purchasing Dean
Foods, we get the same expected growth rate at a 30% lower P/E.

   We remain convinced that over time, owning less expensive stocks relative to
their future prospects will be more rewarding than owning expensive stocks. We
expect this to be true both on an absolute and on a risk-adjusted basis. Our
task is to find value in an expensive market environment, and to wait patiently.

   Year to date, and for the last 12 months the SAFECO High Yield Bond Fund
returned 4.21% and 11.10% for Class A shares and 3.78% and 10.27% for Class B
shares, not including the effects of sales charges, respectively, while the
average high-yield fund returned 4.40% and 11.45% according to Lipper Analytical
Services, Inc. The Merrill Lynch High Yield Master Index returned 4.58% and
11.80%. Our Fund's return is in line with the two groups, largely because of the
well-diversified nature of our holdings.

*The Funds inception was September 7, 1988.  Graph and average annual return
comparison begins September 30, 1988.
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived  from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for  Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated  to reflect Rule 12b-1 fees prior to September 30, 1996  (initial
public offering date of Class A and  Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past  performance is not predictive of future results. Principal value
may fluctuate so that shares,  when redeemed, may be worth more or less than
their original cost.

became increasingly treacherous to navigate. There are a number of reasons for
the change in market conditions including a significant deceleration in cash
flowing into high yield mutual funds beginning in late April, an uptick in the
Moody's default rate over the three months between March to May from 2.18% to
2.53%, indicating an increase in the riskiness of the market, and continued
concerns about Asia's woes, and how this will impact the domestic U.S. economy.
All of these factors contributed to investors demanding more compensation
(yield) for owning "junk" bonds, which in turn led to lower prices overall.
   I have emphasized domestically-oriented companies in my purchases for the
Fund during the first half of the year. The strength in the U.S. economy is
currently coming from domestic consumption, particularly consumers. At the same
time, U.S. exporters are struggling, and our trade deficit is widening.
Companies such as Ziff-Davis, Niagara Mohawk Power, 21st Century Telecom and
Level 3 Communications should do well in this environment, and are among the
names added to the portfolio since year-end.
   Ziff-Davis is the largest technology publisher in the country (PC MAGAZINE,
PC WEEK, and COMPUTER SHOPPER are among the numerous titles they produce). In
addition, the company also produces trade shows and conferences worldwide, among
them the Comdex computer events. They

   Niagara Mohawk is an electric utility serving upstate New York. The company
is an improving credit story and is positioned well for the deregulated
electricity market evolving in its service territory over the next two years.
Niagara is selling their generating assets and will become a low-risk
distributor of electricity.
   I sold holdings in United Refining, PhoneTel Technologies, and
Gorges/Quick-to-Fix Foods during the quarter because of poor operating
performance, and unfavorable outlooks. Over time, each of these names has seen
leverage increase and cash flow deteriorate. I felt in each case that the high
degree of downside risk warranted our exiting the bonds.
   In my last letter to you, I said that I was cautiously optimistic about the
high yield market. The same can be said today. In the current economic
environment, credit selection, always an important component of my job, will
take on even greater importance. I will continue to look for companies with good
earnings and cash-flow prospects and strong management teams. Thank you for your
continued interest in the SAFECO High Yield Bond Fund.

*The Fund's inception was September 7, 1988.  Graph and average annual return
comparison begins September 30 1988.
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

including the effects of sales charges, versus 8.44% index. For further
comparison, the average intermediate-term U.S. Treasury fund returned 3.44% for
the six and 9.55% for 12 months according to Lipper Analytical Services, Inc.
   The fund outperformed its benchmark index because its average maturity at 6.0
years is longer than the index at 3.7 years. During a period of declining
interest rates, which we have experienced, longer maturities perform better,
everything else being equal. The Fund was also overweighted in U.S. agencies,
which outperformed, compared to its benchmark index in June. On June 30 the Fund
had 24% of assets invested in U.S. agency securities while the index had 16%.
   The economic environment for bonds has been quite good for the last year.
While the strength in the economy has been worrisome for the bond market, the
moderate rate of price inflation has been just the tonic to keep the bond bears
in check. Problems in Asia along with good news in inflation, have caused the
Federal Reserve Board (Fed) to be

more cautious than they might normally be in the face of such a strong economy.
The Fed has made no move to change interest rates since March 1997.
   The focus of economic problems in Asia shifted to Japan in the second quarter
of 1998. As concerns about Japan grew, the yen weakened against the dollar and
prompted a flight to quality, with many foreigners abandoning their Asian issues
and buying U.S. Treasury securities as a safe haven. We experienced a bond
market rally--especially in the benchmark 30-year treasury-- which had little to
do with U.S. economic fundamentals.
   The mandate of the Intermediate-Term U.S. Treasury Fund is to buy U.S.
Treasury securities with maturities between three and 10 years. The primary tool
I have to distinguish this Fund from the index and its peers is setting the
average maturity.
   We believe the United States is in the middle of a long-term secular decline
in interest rates. While interest rates may rise and fall as dictated by the
business cycle, the general trend is down. For that reason, we want to maintain
the average maturity of the fund longer than the its benchmark index and benefit
from the

better performance of longer bonds.
   Trading in the fund has been minimal and has focused on maintaining an
average maturity in the range of 6 to 6.5 years. We have also modestly increased
the weighting in U.S. agencies. That paper now provides relatively more yield as
the spring's strong rally in U.S. Treasuries caused their yields to fall.
   While the long-term outlook is for lower rates, the near- term is more
problematical. For more than a year we have enjoyed a near perfect bond
environment, with the economy strong and price inflation subdued. The strength
in the economy has continued longer than most forecasters envisioned, and we are
seeing some signs of inflation accelerating. The Federal Reserve Board, to head
off inflation, may be forced to begin raising interest rates at the end of this
year or early in 1999. We believe we can get through this period without the Fed
acting, but concede there is a nearly 50% probability they will begin raising
rates by February 1999.
   If the Fed does move to raise rates, I would expect to significantly shorten
the average maturity of the portfolio to be more closely aligned with the
benchmark index.

*The Fund's inception was June 25, 1992.  Graph and average annual return
comparison begins February 28, 1994 (initial public offering).
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

                   REPORT FROM THE MANAGED BOND FUND MANAGER
 
   Last year, I made some strategic changes to increase the Fund's
competitiveness, adopting a more balanced approach. I limited the range in which
the portfolio's average maturity would be allowed to fluctuate and concentrated
my efforts on creating additional value through sector rotation, yield curve
positioning and credit selection.
   The market environment over the last 12 months has been particularly
favorable towards fixed-income securities. Inflation is low and shows no signs
of accelerating. The economy, which grew very rapidly during the first quarter,
is showing welcome signs of moderation due to the continuing Asian economic
crisis. The Federal Reserve, which has not

changed the Fed Funds Rate since March 1997, is likely to remain on hold for the
next several months, at least. The growing federal budget surplus is shrinking
the available supply of U.S. Treasury Bonds, causing them to richen.
   The objective of the Managed Bond Fund is to provide as high a level of total
return as is consistent with relative stability of capital through the purchase
of investment-grade debt securities. Preservation of capital is in part achieved
by the fund's mandate to maintain a 50% weighting in U.S. government securities.
The Fund makes modest changes in its average maturity in response to interest
rate trends and further distinguishes itself from its index and its peers
through selection.

   During the quarter, we moved portions of the portfolio into and out of
investment-grade corporate bonds as this sector cheapened, richened and
cheapened again relative to U.S. Treasuries. We sold some government and
corporate holdings in the very rich 10-year maturity sector of the yield curve
and bought a higher-yielding combination of securities

with maturities of two and 20 years. Finally, we concentrated our holding in
issues insulated from the problems in Asia, such as U.S. Treasuries and agency
mortgage-backed securities and notes.
   At quarter end, the Fund held 47% of its assets in U.S. Treasury obligations,
21% in high-grade corporate bonds, 20% in mortgage-backed securities, 1% in U.S.
agency debentures, and 7% in AAA asset-backed securities. The portfolio's
effective duration was 5.7 years on June 30, 1998, slightly longer than the
duration of the Lehman Brothers Government/Corporate Bond Index at 5.5 years.
   The wild card for the fixed-income markets is the continuing Asian economic
crisis. If the crisis continues to worsen, U.S. economic growth could be
adversely affected. Under this scenario, U.S. Treasuries will increase in value
due to a flight to quality from global investors, diminished inflationary
pressures, and the perception that the next Fed move will be to lower interest
rates. Corporate bonds would underperform Treasuries as earnings come under
increased pressure. If the Asian economic crisis abates, U.S. economic growth
could re-accelerate, increasing inflationary pressures and the likelihood of a
Fed tightening. Under this scenario, U.S. Treasuries would decrease in value and
corporate bonds would outperform. We will watch the world economy closely and
invest accordingly.

                                OVERVIEW OF THE
                           SAFECO MUNICIPAL BOND FUND
                   AND SAFECO CALIFORNIA TAX-FREE INCOME FUND
                                 June 30, 1998

   The municipal bond market was little changed for the quarter and six months
ending June 30, 1998, and total returns were modest for both periods.
   In a flat market the three keys to performance are: 1. staying fully invested
since bonds yield more than money market instruments; 2. holding the longest
bonds available because longer bonds yield more than shorter ones; and 3. buying
the lower quality bonds because lower-rated bonds yield more than higher-rated
ones. I have consistently practiced the first two strategies, but I am reluctant
to downgrade quality. The meager additional yields that lower-quality bonds
currently offer don't seem worth the additional risk. Fortunately, two out of
three has been good enough to produce good results.

   Over the last six months, long-term municipal yields fluctuated only slightly
to end the period at 5.22%. The taxable bond market rallied much more
aggressively and long Treasury yields fell to 5.63% on June 30. (On June 15 the
U.S. Treasury 30-year bond closed at a yield of 5.57%, the lowest yield in the
18-year history of the long-term government bond.)
   The underperformance by the tax-exempt market caused the ratio of tax-exempt
to taxable bond yields to rise to 93%. This means munis currently pay on a
tax-free basis 93% of what a similar-length taxable treasury bond yields. This
is the highest ratio since 1995 and compares to 84% one year ago.
   There are two reasons for the extraordinary cheapness of the muni market: low
absolute yields and heavy new issue supply. Yields near 25-year lows, coupled
with the record-high stock market returns, have created little demand for
long-term muni bonds. On top of this, is a new issue market, which brought $146
billion in supply over the last six months.
   At the same time, the U.S. Treasury market has enjoyed increased demand from
foreign investors fleeing weakened Asian currencies and benefited by shrinking
supply due to the

Federal budget surplus. It is no surprise that munis are cheap compared to
Treasuries. And that creates an attractive opportunity for high tax bracket bond
investors.
   In the extremely stable market that municipal bonds have enjoyed this year,
the only aberration is the relationship between tax exempt and taxable bonds. As
long as current economic conditions persist, however, I don't see this changing.
Historically, low rates will continue to encourage issuers of new debt while
discouraging investors. The best hope for the municipal market is a correction
in the stock market, which would encourage equity buyers to reevaluate their
asset allocation and to see bonds in a more attractive light.

   The SAFECO Municipal Bond Fund returned 2.63% and 10.06% for Class A shares
and 2.23% and 9.26% for Class B shares, not including the effects of sales
charges, for the six months and 12 months ended June 30, 1998, compared to its
peer group's 2.26% and 8.39% total returns. According to the Lipper Analytical
Services, Inc. ranking of general municipal bond funds, Class A shares were 10th
and Class B shares were 31st of the 233 fund classes tracked.
   The Fund classes slightly underperformed the 10.77% posted by the Lehman
Brothers Long municipal bond index for the 12 months ended June 30, 1998, but
that is to be expected. It's nearly impossible for a bond fund to beat a bond
index because the index has no expenses, no cash

The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

charges, Lipper Analytical Services, Inc. ranked Class A shares third and Class
B shares 10th of 100 California tax-exempt funds, which returned 8.61% on

The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

   The Fund came in below the Lehman Brothers Long Municipal Index return of
10.77%, which is a national index and not as valid a performance yardstick as
other Washington funds which participate in a limited market that is currently
high-priced with few attractive selections. This is

*The Fund's inception was March 18, 1993.  Graph and average annual return
comparison begins March 31, 1993.
 
The performance graph compares a hypothetical $10,000 investment in Class A
and Class B of each Fund to a hypothetical investment in a relevant market
index. Fund performance is derived from the Fund's original class of shares
and reflects the maximum 4.5% sales charge for Class A shares, and the
maximum contingent deferred sales charge (5% in the first year, decreasing to
0% after six years) for Class B shares. Fund performance has not been
restated to reflect Rule 12b-1 fees prior to September 30, 1996 (initial
public offering date of Class A and Class B shares). Such fees will affect
subsequent performance.
 
The index is unmanaged and includes no operating expenses or transaction
costs. Past performance is not predictive of future results. Principal value
may fluctuate so that shares, when redeemed, may be worth more or less than
their original cost.

             REPORT FROM THE WASHINGTON MUNICIPAL BOND FUND MANAGER
 
due to a scarcity of long local bonds, high demand and the type of deals coming
to market. Further skewing the comparison is the fact that a bond index has no
expenses, no cash and no call features.
   The Fund had a large inflow of cash (about 5 percent of net assets) at the
end of the first quarter. I bought Spokane General Obligation (GOs) bonds on
March 23. Unfortunately, Murphy's Law applied, and the money left in early April
necessitating the sale of the Whatcom GOs. In May, the Fund received another
large inflow. I bought Seattle Water System Revenue bonds and a new issue of
Seattle Wastewater bonds came to market. Neither one was cheap, but preferable
to money market rates. Both Seattle bonds have good structure with 5% coupons
and 2027 maturities that extend the Fund's duration.
   As of June 15, the Fund may invest in bonds subject to the Alternative
Minimum Tax (AMT). As always, I will continue to look for long, discount bonds
that represent value in the market. With a longer duration, the Fund should
outperform its peer Washington Funds during market rallies when interest rates
drop.

                          REPORT FROM THE FUND MANAGER
                            SAFECO MONEY MARKET FUND
                                 June 30, 1998
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
 
   In the 12-month period ending June 30, 1998, the SAFECO Money Market
Fund's total return was 4.88% for Class A shares and 4.81% for Class B
shares, not including the effects of sales charges. This was slightly lower than
the average money market fund return of 4.96%, calculated by Lipper Analytical
Services, Inc. The Money Market Fund's return was very attractive compared to
the Consumer Price Index, which rose 1.68% for the 12 months ending June 30,
1998.                        [PHOTO OF NAOMI URATA]
 
   For the six months, the Fund returned 2.35% for Class A shares and 2.30% for
Class B shares, not including the effects of sales charges, compared to the peer
funds' return of 2.42%.
   Interest rates from 1 to 120 days remained inverted over the first half of
the year (the one-day rate was more than the 120-day rate), reflecting a belief
that the Federal Reserve will not change the Federal Funds rate in the near
term. From 120 days out to one year, yields climbed sharply reflecting the
possibility that the Fed may take action toward the end of the year.
   It appears that the Fed will hold rates steady for the third quarter, but may
increase rates slightly toward the end of the year if growth continues at a high
pace. On the one hand, the Asian crisis is expected to slow the Gross Domestic
Product growth from 5.4% in the first quarter to about 1.2% due to a
deterioration in trade and a reduction in inventories. On the other hand,
consumer spending remains very strong, and we see a modest pick up in consumer
prices, especially medical care.
   As a result, I have been buying securities with short maturities out to 30
days and long securities in the one-year area. This lowered the average maturity
of the Fund from 83 days on December 31, 1997 to 53 days on June 30, 1998. As
the one-year pieces mature I plan to buy more, although the yields are lower now
than when I first started buying them a year ago.

                      REPORT FROM THE MONEY MARKET MANAGER
 
   I diversify the portfolio so that I have no more than 5% of any one issuer. I
look for issuers with a large amount of commercial paper to distribute or with
slightly lower ratings as their offerings are often cheaper. I added some new
names to the portfolio to take advantage of the attractive overnight rates. Two
large issuers of overnight securities I added were BP America, a subsidiary of
British Petroleum, and UBS Finance, a financing arm of Union Bank of
Switzerland. I hold a number of floating rate securities with attractive yields.
If the Fed should start to raise rates, these floaters will help the Fund to
respond quickly as their interest rates roll to the higher levels.

1.  GENERAL
   This financial report is on the 15 SAFECO Mutual Funds that issue Class A and
Class B shares (collectively, "Advisor Classes"). Each Fund is a series of one
of the following trusts (each a "Trust") listed below. Each Trust is registered
under the Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company.
 
         SAFECO Common Stock Trust
              SAFECO Growth Fund
              SAFECO Equity Fund
              SAFECO Income Fund
              SAFECO Northwest Fund
              SAFECO Balanced Fund
              SAFECO International Stock Fund
              SAFECO Small Company Stock Fund
              SAFECO U.S. Value Fund
 
         SAFECO Taxable Bond Trust
              SAFECO High-Yield Bond Fund
              SAFECO Intermediate-Term U.S. Treasury Fund
 
         SAFECO Managed Bond Trust
              SAFECO Managed Bond Fund
 
         SAFECO Tax-Exempt Bond Trust
              SAFECO Municipal Bond Fund
              SAFECO California Tax-Free Income Fund
              SAFECO Washington State Municipal Bond Fund
 
         SAFECO Money Market Trust
              SAFECO Money Market Fund
 
   Effective September 30, 1996, certain SAFECO Mutual Funds began issuing two
new classes of shares--Class A and Class B shares. These classes of shares are
sold by financial advisors to shareholders and have associated sales and
distribution charges, unlike the no-load class of shares (which are sold
directly to the shareholder with no associated sales or distribution charges).
Each class of shares represents an interest in the net assets of the fund.

   In connection with issuing the Advisor Classes, the Funds adopted a Plan of
Distribution (the "Plan"). Under the Plan, each Advisor Class (with the
exception of the Money Market Fund Advisor Classes) pays the distributor, SAFECO
Securities, Inc., as a service fee for selling its shares at the annual rate of
 .25% of the average daily net assets of the Advisor Class. Class B shares also
pay the distributor a distribution fee at the annual rate of .75% of the average
daily net assets of the Class B shares.
   Under the Plans, the distributor uses the service fees primarily to
compensate persons selling Advisor Class shares for providing ongoing services
and the maintenance of shareholder accounts. The distributor uses the
distribution fees primarily to offset the commissions it pays to financial
advisors for selling Class B shares.
 
2.  SIGNIFICANT ACCOUNTING POLICIES
   The following is a summary of significant accounting policies consistently
followed by the Funds in the preparation of their financial statements. The
policies are in conformity with generally accepted accounting principles, which
permit management to make certain estimates and assumptions at the date of the
financial statements.
   SECURITY VALUATION. Investments in equity securities are valued at the last
reported sales price, unless there are no transactions in which case they are
valued at the last reported bid price. Bonds are stated on the basis of
valuations provided by a pricing service, which uses information with respect to
transactions in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining value. When valuations are not readily available, securities are
valued at fair value as determined in good faith by the board of trustees.
Temporary investments are valued at amortized cost which approximates market.
   SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
The cost of the portfolios is the same for financial statement and federal
income tax purposes. Realized gains and losses from security transactions are
determined using the identified cost basis.

                                  (Unaudited)
 
   SECURITIES PURCHASED ON A WHEN-ISSUED BASIS. Securities purchased on a
when-issued or delayed basis for the Taxable Bond Trust, Managed Bond Trust and
Tax-Exempt Bond Trust may be settled a month or more after the trade date. The
securities purchased are carried in the portfolio at market and are subject to
market fluctuation during this period. These securities begin earning interest
on the settlement date. As commitments to purchase when-issued securities become
fixed, the Funds segregate liquid assets in an amount equal to the total
obligation.
   INCOME RECOGNITION. Dividend income less foreign taxes withheld (if any) for
the Common Stock Trust is recorded on the ex-dividend date or upon receipt of
ex-dividend notification in the case of certain foreign securities. Bond
premiums and original issue discounts are amortized to either call or maturity
dates for the Managed Bond Trust, Tax-Exempt Bond Trust and Money Market Trust.
Market discount on bonds purchased after April 30, 1993 is recorded as taxable
income at disposition for the Tax-Exempt Bond Trust. Interest is accrued on
bonds and temporary investments and bonds daily.
   DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. For the Growth, Northwest,
International, and Small Company Funds, net investment income (if any) is
declared as a dividend to shareholders as of the last business day (ex-dividend
date) of December. For the Equity, Income, Balanced, and U.S. Value Funds, net
investment income (if any) is distributed as of the last business day of March,
June, September and December. Net investment income for the Taxable Bond Trust,
Managed Bond Trust, Tax-Exempt Bond Trust and Money Market Trust is declared as
a dividend to shareholders as of the close of each business day and payment is
made as of the last business day of each month. Net realized gains on
investments, if any, are normally distributed to shareholders at the end of
December.
   Income dividends and capital gain distributions are determined in accordance
with income tax regulation which may differ from generally accepted accounting
principles. These differences are primarily due to differing treatments for
foreign exchange contracts. Undistributed/

overdistributed net investment income may include temporary financial reporting
and tax basis differences which will reverse in the subsequent year.
   FEDERAL INCOME AND EXCISE TAXES. Each Fund intends to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies by distributing substantially all taxable income to their shareholders
in a manner which results in no tax to the Funds. Therefore, no federal income
or excise tax provision is required. In addition, the Tax-Exempt Bond Trust
intends to satisfy conditions which will enable them to pay dividends which, for
shareholders, are exempt from Federal income taxes. Any portion of dividends
representing net short-term capital gains, however, is not exempt and is treated
as taxable dividends for Federal income tax purposes. In addition, income which
is derived from amortization on bonds purchased below their issued price after
April 30, 1993, is treated as ordinary income for Federal income tax purposes.
   FOREIGN CURRENCY TRANSLATION. The accounting records of the International
Fund are maintained in U.S. dollars. All assets and liabilities initially
expressed in foreign currencies are converted into U.S. dollars at prevailing
exchange rates. Purchases and sales of investment securities, and dividend and
interest income, are translated at the rates of exchange prevailing on the
respective dates of such transactions. The International Fund does not isolate
that portion of the results of operations resulting from changes in foreign
exchange rates on investments from the fluctuations arising from changes in
market prices of securities held. Such fluctuations are included with the net
realized and unrealized gain or loss from investments. Reported net realized
gains or losses from foreign currency transactions arise from gains or losses
realized between the trade and settlement dates on securities transactions, the
difference between the amounts of dividends, interest, and foreign withholding
taxes recorded on the International Fund's books and the U.S. dollar equivalent
of the amounts actually received or paid. Net unrealized foreign exchange gains
and losses arise from changes in the value of assets and liabilities other than
investments in securities, resulting from changes in the exchange rate.

   FOREIGN EXCHANGE CONTRACTS. The International Fund may enter into foreign
currency exchange contracts as a way of managing foreign exchange rate risk. The
International Fund may enter into these contracts for the purchase or sale of a
specific foreign currency at a fixed price on a future date as a hedge or
cross-hedge against either specific transactions or portfolio positions. The
objective of the International Fund's foreign currency hedging transactions is
to reduce the risk that the U.S. dollar value of the International Fund's
foreign currency denominated securities will decline in value due to changes in
foreign currency exchange rates. All foreign currency exchange contracts are
"marked-to-market" daily at the applicable translation rates resulting in
unrealized gains or losses. Realized and unrealized gains or losses on foreign
currency contracts are recorded on settlement date of the foreign currency
exchange contract and are included in the Statements of Assets and Liabilities
and the Statement of Operations. Risks may arise upon entering into these
contracts from the potential inability of counterparties to meet the terms of
their contracts and from unanticipated movements in the value of a foreign
currency relative to the U.S. dollar.
