 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.

   Contributing to the Growth Fund's success in 1997 were our radio stocks, the
acquisitions of several companies we owned, and an underweighting in technology.
Our overall success is due to one thing: stock picking.
   Its good performance discovered, money poured into SAFECO Growth. Assets grew
from $262 million at June 30, 1997 to $644 million at year end. I used the new
money to start some new positions and add to old favorites. Most importantly, I
was able to keep up performance as the new money came in.
 
   I bought Philip Morris, Avon and Boston Scientific (medical technology). The
advantage of investing in these larger cap stocks is that the money goes right
to work and is readily accessible when more intriguing opportunities arise.
   I started a new position in Green Tree Financial, a company the fund has
owned in the past. Green Tree's price had fallen on two counts. Wall Street
didn't like its accounting and the entire sub-prime lending sector was under
pressure. Green Tree's core business is financing manufactured

                      REPORT FROM THE GROWTH FUND MANAGER
 
housing, but it is branching into other areas of lending.
   I sold Jackson Hewitt, on the news that it would be acquired. The
stock traded up so high, it seemed there was no place left for it to
go. By selling it, I sold the downside risk that's inherently higher in
highly-valued securities.
   Jackson Hewitt wasn't our only stock to rise on acquisition news. INBRANDS,
SFX Broadcasting, American Radio and Suburban Ostomy, all climbed for the same
reason.

   My favorite stocks continue to be those that haven't yet been discovered and
because they are "unfound" they have ample room to appreciate. Currently they
include Family Golf Centers (driving range facilities), MICROS Systems (point of
sale inventory systems), Tetra Technologies (recycles chemical waste
into specialty chemicals) and United Stationers (office product
distributor).
   Despite the fact SAFECO Growth Fund has been discovered, I remain
the same. And I will keep investing with the same attitude I've held for all
these years: think "outside of the box". I'll keep trying to think and invest
creatively and doing that, I hope to uncover and take opportunities that others
fail to see.

 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.

and Viacom, in favor of stocks with greater earnings predictability.
   Within the Viacom organization, Blockbuster had continued to languish. Unable
to overcome competition for leisure time attention, the video division made
Viacom a "B-grade" stock and we took it off our list.
   Advanta effectively became a higher risk stock by aggressively offering low
introductory rates in its pursuit of market share. The company soon accumulated
$10 billion in credit card receivables issued to what turned out to be higher
risk users.
   Mid year, PacifiCare discovered the HMO it acquired, FHP, was in poorer
financial shape than anticipated. That news sent the stock reeling. We held our
position, looking for a come back. Instead the picture grew darker and the stock
blew up a second time.
   Even though we outperformed our peers in the fourth quarter, trouble in
technology stocks took a toll on overall returns. High-profile tech stocks
started to miss their numbers. Oracle's stock, off 41% for the quarter, was
brutalized as the company missed earning estimates for the first time in half a
decade. Intel, off 24%, was also punished for disappointing earnings, as were
3Com and First Data, down 35% and 31%, respectively.

                      REPORT FROM THE EQUITY FUND MANAGER
 
   I worked the downdraft in First Data to our advantage, selling
when its share price began to slip and buying it back later at a
lower price. This company's business, credit card processing, is
becoming more crowded, but First Data is still the dominant player.
   Electronic Data Systems, a data processing outsourcing company we own, ended
the quarter on an up note. The company stumbled earlier this year and then
languished' as the quick fix it promised failed to occur. Finally after six
quarters of our owning EDS, it beat expectations and the stock took off.
   I believe more than ever that our strategy is the right one. To make our
50-name portfolio excel in a market that can't tolerate bad news, I am working
to incorporate greater predictability into our equation. I am carefully
considering the sectors in which we invest, and raising the standards for
admission to our portfolio. For example, it's easier to predict Fannie Mae's
earnings than it is to predict Oracle's.
   Thus the theme to our purchases and sales, and subsequently to our fourth
quarter come-back is predictablity. I have added to our stake in
companies whose earnings I have higher conviction: Fannie Mae,
Johnson & Johnson, AlliedSignal and GE. Those additions and good
runs by the same companies have reshaped our top ten holdings.

   Conversely, we are less invested in companies with less predictable
earnings--mainly technology and HMOs. Furthermore, I changed the tone of the
technology we do own to more blue chip by adding to Microsoft and Intel.
   All said, our year ended on an up note. Even better, its a long-term game. In
longer terms, Equity Fund remains well ahead. And, in golf terms: We're going
forward working to get up, get down, stay out of trouble and go on to the next
holding.

                               SAFECO INCOME FUND

   SAFECO Income Fund ended 1997 with a total return of 26.15% for Class
A shares and 25.35% for Class B shares, not including the effects of
sales charges, slightly trailing the Lipper Analytical Services Equity-Income
category at 27.51%.
   As equity income funds typically do in a strong up market, the Fund (and its
peers) underperformed the S&P 500 which returned 33.36%. The
higher-income-producing securities held by SAFECO Income in the form of
convertible bonds and preferred stocks, tend to underperform stocks
(which make up the S&P) in a rising market. They also lower the Fund's
risk profile as they tend to hold up better than stocks in a down market.

 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 INCOME FUND MANAGER
outperformed in the year's last three quarters. American Home Products (AHP)
provided a small boost in the latest quarter. I had increased our stake in AHP
after its share price fell on liability concerns. I also purchased more shares
in American Stores, a food and drug store chain, when its price fell on missed
earnings.
   Despite the fact both these domestic companies experienced dips in the last
six months, I am content to hold them because their revenues are less tied to
foreign countries at a time when international exposure is not so desirable.
   I also currently like smaller domestic companies more than larger ones. One
of them, Chancellor Media, was the largest contributor to our performance in the
latest three quarters. (This radio station holding company actually grew from
small to mid cap on us.) Through appreciation, acquisitions and mergers, the
share price of AMFM has doubled since we bought it. And best of all, the
Chancellor convertible we hold pays a 7% dividend.

   Another small company contribution came from CCA Prison Realty
(PZN). This REIT has moved from $21 to $45 a share since we
purchased it in July. PZN pays an attractive dividend and positions
us to participate in the prison privatization trend.
   Through Family Golf Center's 5.75% convertible, SAFECO Income
Fund is holding a great small company in a way that fits our conservative
risk/reward profile. I made Family Golf our largest position because, I believe
it can grow tremendously over the next couple years. This company acquires and
improves golf driving ranges.
   I'm substantially invested in integrated international oil producers, a
long-standing, high-yielding staple of equity-income funds. I believe these
stocks reduce the overall risk of our portfolio because they tend to be less
volatile than the market as a whole.
   I took our gain in RJR Nabisco and reduced exposure to tobacco stocks because
the tobacco settlement process had become more politicized. In my estimation, a
politically negotiated settlement-- which is what's happening--is more difficult
to analyze than a solution determined on a case-by-case basis in the courts.
   We're invested in technology, albeit conservatively, in an amount
comparable to the S&P 500. Compared to the broad market, our tech
companies have lower exposure to Asia and are less cyclical. As
well, many of our investments are held in convertible debt
securities.

   The fund remains fully invested in domestically-oriented companies, and
that's attractive given today's environment. I believe the biggest risk in the
market right now is the damage an Asian recession could do. I anticipate the
Asian economies will experience serious recessions and I think our domestic
economy will slow because of it. Slow, but not recede-- and, that is why I'm
continuing to invest at home. Overall, the outlook for our markets, and your
Fund, remains constructive.

   Returning 30.79% for Class A shares and 29.93% for Class B shares, not
including the effects of sales charges, SAFECO Northwest Fund finished
1997 well ahead of its peer funds and slightly behind the broad market.
Respectively, the average growth fund delivered 28.08% as measured by Lipper
Analytical Services and the S&P 500 returned 33.36%.
   The Fund was outpacing the S&P 500 going into the fourth quarter, but
fell behind during the Asian crisis.

   Asia was the biggest factor in the entire market's fourth quarter
performance, with the Northwest Market being hardest hit. No region has a larger
stake in exporting, and most of that involves the Pacific Rim. And because the

 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 NORTHWEST FUND MANAGER
Northwest Fund has substantial exposure to exporting, the Asia epidemic affected
our portfolio as well.
   Boeing, Schnitzer Steel, Lattice Semiconductor and Expeditors all suffered
with the Asian Flu. Innova declined on the perception that developing countries
would be less able to buy their wireless technology. In all these cases the
problems are more perceived than real. In other words it's expectations, not
orders, that are off.
 
   And while exports were the wrong place to be in the fourth quarter, I'm
convinced they are an important place to be invested long-term. In fact, I added
to our holdings in both Expeditors and Innova after their share prices dropped.
Innova, with only 6% of its business tied to Asia, was simply too cheap to pass
up. And, Expeditors is a net importer of goods. A stronger US dollar should
actually increase its business.

   Our best fourth-quarter performers were companies that do
business locally. Regional banks prospered. QFC, Fred Meyer,
Albertson's and Costco all posted substantial gains. I sold QFC on
the news that Fred Meyer would acquire the grocery chain. Had I kept both names
we would have had 9% of net assets invested in the new company.
   I sold Assisted Living Concepts for the gain, and I sold PacifiCare for the
tax write off. I bought PacifiCare's stock after it blew-up in June,
anticipating a swift recovery for the HMO. Unfortunately, the stock tumbled a
second time when it became clear PacifiCare's merger with FHP wasn't going well.
   The only position of any size I initiated in the last quarter was Protocol
Systems, a medical monitor supplier in Oregon. I like Protocol and I wanted to
keep our weighting in healthcare up.
   By taking our gains in connector company AMP, I sold the only
non-Northwest company remaining in our portfolio. Every one of the
35 companies we now own has operations in the Northwest.

   I feel the portfolio is well positioned for 1998. One of the analysts or I
closely follow each company we own. And that's the way it should be. After all,
they're our neighbors.

   The SAFECO Balanced Fund returned 16.29% for Class A shares and 15.21%
for Class B shares, not including the effects of sales charges, for the
year ending December 31, 1997, while the average balanced fund returned 20.05%
according to Lipper Analytical Services. A 60%/40% composite of the S&P 500 and
the Lehman Government/Corporate index returned 23.65%.
   There are three main reasons the SAFECO Balanced Fund under-performed
the average balanced fund. The latter two also explain why we lagged the
composite index.             [PHOTO OF REX BENTLEY]

 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.

that of the average fund. This same allocation helped the fund outperform
its peers in the fourth quarter when bonds provided a better return than
stocks. At current stock valuations, we are not inclined to raise the
equity allocation and are confident our target of 60% stocks and 40%
bonds is appropriate.
   Second, the equity portion of the portfolio is underweighted in financial
stocks, which for the third consecutive year posted superior results.
Because financials have traded up so high, we are very comfortable
limiting our exposure to them.

   Third, we purchased several stocks including Electronic Data Systems

Unisource Worldwide (paper distributor) as they declined on what we still
believe to be temporary setbacks. Even though these stocks continued to decline
after they were purchased, we

                     REPORT FROM THE BALANCED FUND MANAGERS
 
believe they represent excellent value with significant upside
potential.
   On the whole, 1997 was another outstanding year for U.S.
financial markets. It was also peculiar, especially on the equity
side where the stock market's advance was quite narrow. About 50
stocks, or 10% of the index's 500 stocks, accounted for 63% of the S&P 500's
33.36% return.
   And, the year ended on a sober note. The technology sector, which has had
strong performance for some time, declined 12% last quarter on signs of
weakening demand and shrinking profit margins. Concern over financial problems
in Asia resulted in a one-day drop in U.S. equity prices of over 7%. Although
stocks recouped much of their losses the following day, it was another reminder
that stocks don't always go up.

   We sold Bristol Myers Squibb, PepsiCo and Raytheon because they reached our
price targets. We sold Advanta and 3Com because of deteriorating fundamentals.
   We purchased new positions in companies we think are well
positioned in their markets and selling at attractive valuations,
including Boeing. The airplane manufacturer has had major success in
obtaining new orders, but temporary production problems have
restrained its stock price.
   We bought Intel in December, after it had declined 30% from its yearly high.
We expect these and new positions in General Signal (a diversified manufacturer
of electrical equipment), Johnson & Johnson, and Praxair (supplier of industrial
gases) to improve the risk/return profile of your portfolio.
   At year end, the stocks in the Fund sold at a 17% discount to the S&P 500's
P/E (price to earnings ratio) based on 1998 expected earnings per share. The
Fund's stocks had a 29% higher dividend yield than the S&P 500. And, we think
our stocks can produce roughly the same level of earnings growth as the S&P 500
stocks over time.
   Bonds performed well in the fourth quarter, benefiting from a

strong U.S. dollar, turmoil in the Asian markets and continued low inflation.
The yield curve remains very flat and we are emphasizing intermediate-term
maturities.
   The fixed-income portion of the Balanced Fund has a sensitivity to interest
rates that is slightly higher than the general market. We are modestly
overweighted in high-quality corporate and mortgage-backed bonds and
underweighted in U.S. Treasury and Agency bonds.
   While the investment environment remains quite good, there are reasons to be
cautious. We attempt to factor these variables into our decisions, keeping in
mind both the potential rewards, and the possible risks. We believe the Balanced
Fund is well positioned on both counts.

                          REPORT FROM THE FUND MANAGER
                           SAFECO INTERNATIONAL FUND
                               December 31, 1997

- --------------------------------------------------------------------------------
 
   For the 12 months ended December 31, 1997, SAFECO International Fund returned
4.30% for Class A shares and 3.48% for Class B shares, not including the effects
of sales charges, while the average international fund returned 7.27% according
to Lipper Analytical Services. Meanwhile, the MSCI EAFE (Morgan Stanley Capital
International Europe, Australasia, Far East Index) returned 1.78%.
   With the notable exception of South East Asia and the Far East, global equity
markets performed strongly during 1997. Underpinning the strong performances was
the almost universal phenomenon of steady economic growth and low inflation.
   Asia experienced a succession of economic and political upheavals during the
second half of the year that started in Thailand in May and continued across
South

</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.

East Asia and into the Far East. The structural problems in the region were
exacerbated by the head-in-the-sand approach of political leaders whose
reactions to the problems have damaged, rather than restored, confidence in the
region.
   Europe in general did well during the year on the back of lower interest
rates, increasing signs of economic recovery and evidence that management was
paying greater attention to shareholders' interests. In the U.K. strong
corporate earnings results, particularly from the financial services sector, and
the expectation of corporate restructuring supported a solid year in the equity
market.
   The prevailing low-interest rate environment has been one of the main
linchpins of equity market strength. Consequently, on a thematic basis, Positive
Banking Environment added significant value to the portfolio. U.K. quoted
Barclays Bank was the biggest contributor to the theme's overall performance.
   Healthcare Needs was also a positive contributor. The top performer in this
theme was the

fund's largest holding, Novartis. In its first full year since its formation by
the merger of Ciba Geigy and Sandoz, it became apparent that the benefits of the
alliance were having a much quicker-than-anticipated impact on performance.
Glaxo Wellcome was an impressive performer during 1977, even though its best
selling drug, Zantac has come off patent. New drugs to treat asthma, AIDS, and
migraines are expected to increase Glaxo's sales.
   Consumer-oriented stocks in Leading Consumer Franchises did well during the
year. The largest holding in this theme, B.A.T. Industries, announced a merger
between its finanical services divisions and Zurich Insurance group.
   On the negative side, themes with companies quoted in, or with earnings
exposure to, South East Asia and the Pacific Basis suffered. Examples of these
are Infrastructural Development and Expanding Finanical Services in Developing
Markets and Increased Consumer Spending in the Pacific Basin.
   While Asia is trying to shake off the hangover of its property binge, we are
unlikely to allocate any further funds to the region unless, and until, we see
an overwhelming and decisive policy responses by the various governments in the
region. We anticipate Asia's rehabilitation will be slow because its governments
have been reluctant to admit the extent of their problems.
   However, despite the government's inaction, selective Japanese companies have
restructured their operations and delivered strong earnings growth.
Consequently, during the second half of 1997 we have invested in a number of
Japanese companies which on a relative valuation basis look attractive compared
to the global peers. We continue to monitor other Japanese companies for value
opportunities.
   In Europe and the U.K. the push for European Monetary Union will continue to
play a strong role in 1998. As part of this, merger and acquisitions activity is
likely to remain strong. Financial stocks are most likely to benefit from the
moves but pharmaceuticals and telecommunications are also likely to remain high
on the list of good performing stocks.

                          REPORT FROM THE FUND MANAGER
                           SAFECO SMALL COMPANY FUND
                               December 31, 1997
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
 
   For the 12 months ended December 31, 1997, the SAFECO Small Company
Fund beat its peer funds and benchmark index. The Fund earned a return of
23.21% for Class A shares and 22.23% for Class B shares, not including the
effects of sales charges, versus the small company peer group average of 15.05%
according to Lipper Analytical Services. During the same period the Russell 2000
Index earned 22.36%.
   The third quarter of 1997 saw a continuation of the strong rally in
small capitalization stocks which started in May 1997. (This rally ended
just as October began, and so the Fund actually lost 4.33% for Class A shares
and 4.50% for Class B shares in the fourth quarter of 1997, beating the average
fund which gave up 5.66%.)   [PHOTO OF GREG EISEN]

 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 SMALL COMPANY FUND MANAGER
 
   The fund's outperformance is attributable to stock selection, banks and oil
service companies in particular. Some of the significant stock purchases we made
since our last report include:
   Platinum Software, which is a developer of financial accounting software
packages, and is in a turnaround phase.
   Circle International Group is an integrated freight forwarder that has
already turned around its business. In spite of having to adjust to new
management, Circle was trading significantly cheaper than the competitors in the
industry, with just as bright an outlook.
   Seattle FilmWorks is a direct marketing company that sells photo finishing
services to the public. Over the years FilmWorks has managed to grow its
business at a fast rate in a slow-growth industry by creative marketing. They
attract customers by providing value-added services to the basic photo finishing
product.
   International Aircraft Investors leases used airframes on an operating lease
basis to airlines.

Besides having experienced management, they have a close
relationship with one of the biggest names in aircraft leasing,
International Lease Finance (ILFC). International Aircraft uses this
relationship to acquire planes, usually already on lease, from ILFC.
   1997 was a year in which returns of large capitalization stocks outperformed
small caps. However, I think our "small" slice of the market is now positioned
to take its turn as a leader. The small cap sector looks to be cheaply priced on
a price-to-earnings basis relative to the large cap sector of stocks. In general
smaller cap stocks, especially the stocks held by this Fund, have lower exposure
to international sales than the market as a whole and large cap
stocks in particular. This will help if fears about Asia come to
fruition.
   Looking out to 1998, the fund will remain invested in small cap
stocks that we believe are good businesses at good values relative
to their earnings prospects, or are cheap by some other yardstick we feel is
appropriate. The Fund will remain broadly diversified across the range of
industry sectors.

   On December 31, 1997, the SAFECO U.S. Value Fund completed its second
full calendar quarter. Since inception, April 30, 1997, the portfolio has
achieved a return of 17.24% for Class A shares and 16.63% for Class B shares,
not including the effects of sales charges.
   For the latest quarter, the U.S. Value Fund was basically flat,
returning 0.52% for Class A shares and 0.41% for Class B shares. This is
right in line with the Lipper Analytical Services average for growth and
income funds of 1.05%. (Lipper does not have a Value Fund Universe, but we
believe the growth and income category is a reasonable comparison for the U.S.
Value Fund.)                 [PHOTO OF REX BENTLEY]

 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.

   On the whole, 1997 was another outstanding year for U.S. financial
markets. It was also peculiar, especially on the equity side where the
stock market's advance was quite narrow. About 50 stocks, or 10% of the index's
500 stocks, accounted for 63% of the S&P 500's 33.36% return.
   And, the year ended on a sober note. The technology sector, which has had
strong performance for some time, declined 12% last quarter on signs of
weakening demand and shrinking profit margins. Concern over financial problems
in Asia resulted in a one-day drop in U.S. equity prices of over 7%.
Although stocks recouped much of their losses the following day, it was
another reminder that stocks don't always go up.
   In fact, the characteristic that defines our value style of management
is selecting companies for their potential to generate better earnings growth
than the market, but buying them at a low price.

                    REPORT FROM THE U.S. VALUE FUND MANAGERS
 
excellent value with significant upside potential.
   New positions in other companies we think are well positioned in
their markets and selling at attractive valuations, include Boeing.
The airplane manufacturer has had major success in obtaining new orders, but
temporary production problems have restrained its stock price.
   We bought Intel in December, after it had declined 30% from its yearly high.
We expect these and new positions in General Signal (a diversified manufacturer
of electrical equipment), Johnson & Johnson, and Praxair (supplier of industrial
gases) to improve the risk/return profile of your portfolio.
   We sold Bristol Myers Squibb, PepsiCo and Raytheon because they reached our
price targets. We sold Advanta and 3Com because of deteriorating fundamentals.
   The characteristics of the stocks in the U.S. Value Fund are very attractive
relative to the overall stock market as measured by the S&P 500. At year end,
the stocks in the Fund sold at a 17% discount to the S&P 500's P/E (price to
earnings ratio) based on 1998 expected earnings per share. The
Fund's stocks had a 29% higher dividend yield than the S&P 500. And,
we think our stocks can produce roughly the same level of earnings
growth as the S&P 500 stocks over time.
   In short, our goal is to find and buy companies with better than average
prospects that are selling at discounted prices. We intend to stay fully
invested in companies that will pay you, the shareholder, in dividends while we
wait. We are confident that this approach will result in superior investment
performance over time, factoring in both risk and return.

                          REPORT FROM THE FUND MANAGER
                          SAFECO HIGH-YIELD BOND FUND
                               December 31, 1997
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
 
   Strong domestic economic growth, and low inflation combined to provide
a favorable environment in which the high-yield market turned in another
year of excellent performance.
   Total return for the SAFECO High-Yield Bond Fund for the year ended December
31, 1997 was 12.49% for Class A shares and 11.77% for Class B shares, not
including the effects of sales charges, slightly under both the average
high yield fund, which according to Lipper Analytical Services, returned
12.96%, and the Merrill Lynch High-Yield Master Index, which returned
12.83%.                      [PHOTO OF ROBERT KERN]
   The portfolio is structured for total return and somewhat similarly to the
broad high-yield market which accounts for our returns being in-line with the
index.

 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 HIGH-YIELD BOND FUND MANAGER
 
   At year end, our portfolio was broadly diversified with about 80 holdings
concentrated in cash-paying domestic companies. The telecom sector represented
approximately 8% of net assets. (Telecom is 8% of the Merrill Lynch High Yield
Index.) The Telecom Act of 1996 introduced competition into both the long-
distance and local segments of the industry and this sector has become a large
and important part of the high-yield universe as many companies have come to the
debt and equity markets seeking funding for their network expansions. I added
positions in Intermedia Communications, Qwest Communications, and Telegroup to
the fund.
   Intermedia Communications is a local telephone company that provides
facilities-based services primarily to business users in the Southeastern US.
The company, which has been in a building phase, should turn cash-flow positive
during the second quarter of 1998.
   Qwest Communications is building a high-capacity, long-distance fiber-optic
network along railway right-of-way capable of carrying voice, data, and internet
services. Capacity on the network is sold under contract to long-distance
companies, regional Bell operating companies, and other telecommunications
services providers.

   Telegroup is a global long distance services company whose
established presence, and state-of-the art facilities, should enable
them to capture a healthy share of the European telecommunications
market, as it opens up to competition in 1998.
   When buying bonds, I look at how the issuer will use the funding. I favor
companies that are borrowing to refinance higher-cost debt, expand their
business, or make a prudent acquisition. For example, in October I bought Jitney
Jungle 10 3/8% bonds. This Jackson, Mississippi grocery chain used the proceeds
to acquire DelChamps, another grocer with contiguous markets. Jitney should be
able to cut distribution costs and improve operations of the acquired stores.
   I also established a position in National Equipment Services, a heavy-duty
equipment rental company that intends to grow via acquisition and whose bonds
were attractively priced.
   I built a position in Holmes Products, a manufacturer of home comfort
products including space heaters, air conditioners and dehumidifiers. The
company's products are made under contract in China and are sold through the
major retailers such as Wal-Mart, Costco, Home Depot and through
national drugstore chains.
   I sold bonds I felt offered limited upside potential. Among those
sold were Universal Outdoor, ShopVac and Snyder Oil. Universal
Outdoor was acquired by Clear-Channel Communications, and the bonds traded up
nicely. ShopVac had also appreciated substantially and it was time to put the
money to work in bonds with greater potential. Snyder Oil had also appreciated
in price, and given my negative outlook for oil and gas prices, I felt it
prudent to reduce my exposure here.

   Looking forward to 1998, I am cautiously optimistic about the high-yield
market. I expect healthy economic growth, although at a somewhat slower pace
than was experienced in 1997. The financial turmoil in Asia will have some
effect on U.S. economic performance, but it is too soon to gauge its full
impact. Slower growth out of that region, together with the stronger dollar, may
contribute to continued low inflation thus may preclude the need for the Federal
Reserve to raise interest rates.

                  REPORT FROM THE HIGH-YIELD BOND FUND MANAGER
 
   I will continue to use fundamental credit analysis to identify companies
which offer good relative performance, as well as safety of principal. While I
intend to maintain a well-diversified portfolio, when I believe it is
appropriate and opportunity for outperformance is present, I will overweight
certain market segments (such as telecom currently).

 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 INTERMEDIATE-TERM U.S. TREASURY FUND MANAGER
 
the year. The economic and financial turmoil in Asia in the second half of the
year added impetus to the upward move as investors sought refuge in the safety
of U.S. Treasury bonds. Also investors reckoned that weakness in the Asian
economies and currencies would slow domestic growth and price inflation, making
prospects for bonds positive into the new year.
   We beat the index and peer group by positioning the average maturity of the
fund to take advantage of the economic environment. As longer maturities will
perform better in a declining rate environment, we decided at mid-year we wanted
to position the average maturity of the fund significantly longer than our
benchmark index. At mid-year we lengthened the maturity of the fund. As the year
progressed we took care to remain fully invested to take advantage of rising
bond prices. For this time period the strategy served us well.
   At year end the average maturity of the fund was 6.0 years compared to 3.8
years for the Merrill Lynch index of U.S.

Treasuries, 1-10 Years. Eighteen per cent of net assets were invested in U.S.
Government agencies. The balance was invested in U.S. Treasuries and a small
cash position.
   Bond prices at year end incorporate all the good news on the economic and
inflation front as well as a very optimistic view of 1998. While we too are
optimistic about 1998, we don't expect bond prices to improve significantly from
these levels. We expect bonds to earn their coupon this year while other
financial assets may struggle to earn similar returns. As the new year begins we
plan to keep the average maturity longer than the benchmark index. If the
economic and inflation environment begin to deteriorate we will shorten the
maturity of the portfolio.

 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.

Treasury securities, as Asian-market difficulties produced "flight
to quality" bid for U.S. Treasuries, causing corporate bonds and
mortgage-backed securities to lag. Underperformance relative to the
Lehman Brothers Government/Corporate Index can be attributed to the
nature of the index itself. An index is a "portfolio on paper," it has no cash,
and incurs no transaction costs or fees.

intermediate-term securities in the portfolio. However, unlike my
predecessor, my strategy will not rely on large swings in duration
(lengthening or shortening the average maturity date of the Fund's
bond portfolio, in anticipation of their sensitivity to interest rates) to
distinguish this Fund from its peer group.
   In the past, Fund performance was heavily dependent on the duration decision.
The Fund suffered when its portfolio had a duration that was either too long or
too short and interest rates suddenly changed course. The duration of your fund
will not fluctuate as widely as it had in the past. I plan to keep the portfolio
duration within plus or minus 15% of the benchmark index's duration. While
duration will remain an important factor in my investment strategy, equally
important will be sector positioning, credit selection, and maturity structure
within the portfolio. To the extent the prospectus allows, the Fund will
consider utilizing mortgage-backed securities, triple-

B rated corporate bonds, and securities with maturities longer than ten years.
   During the last quarter of the year, the Fund liquidated some of its U.S.
Treasury holdings in order to take advantage of the softness in the corporate
and mortgage-backed securities sectors of the market. At year end, the Fund held
52% of its assets in U.S. Treasury obligations, 27% in high-grade corporate
bonds, 12% in mortgage-backed securities, 5% in U.S. Agency debentures, 7% in
AAA rated asset-backed securities, and 2% cash. The portfolio's effective
duration was 6.2 years on December 31, 1997, slightly longer than the duration
of the Lehman Brothers Intermediate Government/Corporate Bond Index at 5.3
years.
   The fundamentals behind bond bullishness remain intact. Inflation is under
wraps and even falling. Meanwhile, the dollar is strong, encouraging foreign
investors to buy U.S. bonds. Leading commodity prices are dropping, signaling
that the benign inflationary environment will likely continue. Still, bonds have
come a long way, and will have great difficulty matching 1997 gains-- unless the
Asia crisis substantially impacts the U.S. economy.

                                OVERVIEW OF THE
                           SAFECO MUNICIPAL BOND FUND
                   AND SAFECO CALIFORNIA MUNICIPAL BOND FUND
                               December 31, 1997

   Nineteen ninety seven was a very good year for long-term bonds. While
the financial press obsessed about the stock market and if the bull
market would continue, long-term interest rates quietly dropped to their lowest
levels in 20 years. This produced handsome total returns for all classes of
fixed-income securities.  [PHOTO OF STEPHEN C. BAUER]
 
   The Lehman long municipal bond index had a double-digit total return, 11.31%
for the year. These excellent returns are particularly gratifying because most
economists expected rates to rise during 1997 in the heat of the Federal
Reserve's battle against inflation. The expected increase in inflation did not
materialize, and the Fed's policy of "watchful waiting" proved the right one.
   (Interestingly, in light of financial problems in Asia, there are a few
prognosticators who expect the Fed to ease monetary policy and allow yields to
decline.)
   The Consumer Price Index, a broad gauge of inflation, posted its lowest
annual increase of the nineties, less than 2%. This means that real returns
(returns adjusted for inflation) were almost as high as stated returns.
   Already buoyed by low inflation, the bond market floated even higher
on a strong dollar and increased volatility in the stock market. The
strong dollar attracted foreign investors to our domestic bond market, bidding
prices up and pushing yields down. During the second half of the year money came
to the bond market from the increasingly volatile stock market.
   Our investment strategy for 1998 will be based on the fundamental policies
which have always governed our investing--the same strategy that has produced
our long-term success. We will stay fully invested and resist the temptation to
try to time the market or predict the future. It simply can't be done.
   One of our greatest advantages over our competition is our willingness and
ability to make decisions which may not look good for several years--that is to
buy and hold out-of-favor bonds. If we are correct in recognizing value, the
market will reward us for our patience.
   We think that long-term performance is most important to our shareholders and
so it is most important to us.

                          REPORT FROM THE FUND MANAGER
                           SAFECO MUNICIPAL BOND FUND
                               December 31, 1997
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
 
   The total return for the Municipal Bond Fund was 10.17% for Class A shares
and 9.56% for Class B shares, not including the effects of sales charges for the
year ended December 31, 1997 which compares favorably with 9.10% the average
return for general municipal bond funds reported by Lipper Analytical Services.
Of the 235 funds reporting one-year returns Class A was number 27.
   The Fund slightly underperformed the Lehman long municipal index's return of
11.31%, but this is standard. It's nearly impossible for a bond fund to beat a
bond index because the index has no expenses, no cash and no call features. The
difference in the performance of the Fund and its peer group over the long term
is a better measure of success.

 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.

   As nice as it is to do well for a given year, the more important results are
for the longer time periods. Fortunately, our three, five, and ten-year returns,
which have also been above average, better reflect the results of our long-term
strategy.
   In the world of municipal bonds, it is hard to implement a strategy which has
an immediate impact. Value is often not recognized for two or three years.
Hence, much of the last three year's good performance stems from transactions
done in 1994 when prices fell dramatically. The chaotic markets of that year
provided opportunities to add value to the Fund, even though much of that value
was not fully realized until years later.
   The valuable call protection afforded by the deep discount bonds which are a
hallmark of all the SAFECO Municipal bond funds, came into its own this year.
While bonds priced at par (current interest rates) rose from 4% at mid-year to
5% at year-end, deep discounts rose 6% to 8% in price over the same period.

   The California Tax-Free Fund was again the best performing fund of the SAFECO
Tax-Exempt Bond Trust for the year ended December 31, 1997. The fund delivered

 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.

   For the year ended 1997, the SAFECO Washington State Municipal Bond
Fund returned 8.64% for Class A shares and 7.75% for Class B shares, not
including the effects of sales charges, which was slightly below the 8.68%
average for single state municipal debt funds according to Lipper Analytical
Services. The Lehman long municipal index returned 11.31%.

   My investment strategy is to buy and hold low-coupon, long-term bonds
with maturities of 20 years or more. Finding Washington bonds with this
structure can be difficult, since many Washington state issuers structure their
bonds with shorter maturities and with coupons at current interest rates.

</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.

             REPORT FROM THE WASHINGTON MUNICIPAL BOND FUND MANAGER
 
   To stay fully invested, I sometimes buy bonds with different
structures if I believe them to be a good value. An example would be
the Seattle Housing Authority Low Income Housing Bonds 6.6% coupon,
maturing in 2038. The high coupon (6.6%) is not a typical purchase,
but the long maturity made it more acceptable.
   Falling interest rates during the last half of the year caused many of the
fund's higher coupon holdings to be priced to their call dates instead of
maturity date, effectively shortening the maturity of the portfolio. To help
offset this, I bought the longest maturity (2022) issued by Washington Higher
Education for Gonzaga University. I believe these bonds represent
value in the market given the rarity of the discount coupon, at
4.75%, and the long maturity.

   I will continue to seek to buy bonds at a "good price." By this I
mean a price that is lower than where it normally trades relative to
how other municipal bonds are trading.

                          REPORT FROM THE FUND MANAGER
                            SAFECO MONEY MARKET FUND
                               December 31, 1997
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
 
   In the year ending December 31, 1997, the SAFECO Money Market Fund
returned 4.97% for Class A shares and 4.94% for Class B shares, not
including the effects of sales charges, while the average money market returned
4.90%, according to Lipper Analytical Services. At year end, the Fund's seven
day yield was 4.95% for Class A shares and 4.99% for Class B shares. The money
market fund yields are very attractive compared to the Consumer Price Index that
rose 1.70% for the 12 months ended December 31, 1997.

   Early in 1997, 90-day commercial paper rates fell from 5.30% to 5.20% in
March, when the Federal Reserve raised short-term interest rates. Since that
time, rates have traded in a ranges between 5.45% and 5.72%, ending the year at
5.57%. The yield curve (interest rates for various maturities) out to one year
remained flat throughout the period, reflecting the market's view of very little
risk of inflation and very steady rates going forward.
   Recently, I invested in U.S. agency securities, commercial paper issued by
top tier corporations, bank notes, medium-term notes, certificates of
deposit, taxable municipal bonds and an asset-backed student loan
trust--a broad range of assets to seek the best return for our money market
investors. Seven securities have a rate that floats so investors can benefit
from higher yields if short-term rates rise. For example, I added a Merrill
Lynch & Co. floating rate note based on the prime rate. This security has an
attractive current rate and should continue to perform well. Banks are slower to
lower their prime rates in a falling rate environment and quicker to raise rates
in a rising rate environment.
   I extended the seven-day weighted average maturity of the Fund from 36 days
at January 1, 1997 to 83 days at year end. I accomplished this by adding several
pieces of one-year paper with attractive yields, including Abbey National, a
British bank, with a 5.88% yield and Bayerische Landesbank, a German bank, with
a 5.81% yield.
   It appears that the Federal Reserve will not raise interest rates in the next
few months as

previously thought because inflation has remained low. Oil prices are down due
to greater supplies from OPEC and other countries. The Asian financial turmoil
is expected to reduce demand, keeping prices low. The dollar has increased in
value against Southeast Asian currencies, lowering the cost of imports. As a
result, economists are beginning to think that the next move by the Fed may be
an ease or lowering of interest rates in 1998. The timing is uncertain. I will
continue to keep a longer average maturity to retain higher yielding assets in
the fund as long as possible.

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.

                         NOTES TO FINANCIAL STATEMENTS
 
   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.
   SHAREHOLDER MEETING. On April 10, 1997, the High-Yield Bond Fund held a
special meeting of shareholders who voted to amend the Fund's fundamental
investment policies to exclude certain Rule 144A securities from the definition
of securities which are illiquid or subject to legal or contractual restrictions
on resale. The results of the vote are presented below.

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
require management to make certain estimates and assumptions that affect the
reported amounts and disclosures in the financial statements. Actual results
could differ from those estimates.
   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
 
                                    - 101 -
<PAGE>
- --------------------------------------------
- --------------------------------------------
 
                         NOTES TO FINANCIAL STATEMENTS
 
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.
   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

<PAGE>
- ------------------------------------------------------------------
- ------------------------------------------------------------------
 
                         NOTES TO FINANCIAL STATEMENTS
 
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
 
                                    - 103 -
<PAGE>
- --------------------------------------------
- --------------------------------------------
 
                         NOTES TO FINANCIAL STATEMENTS
 
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.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
To the Board of Trustees and Shareholders of the SAFECO Common Stock Trust,
SAFECO Taxable Bond Trust, SAFECO Managed Bond Trust, SAFECO Tax-Exempt Bond
Trust, and SAFECO Money Market Trust
 
   We have audited the accompanying statements of assets and liabilities,
including the portfolios of investments in securities, of certain Funds of the
SAFECO Common Stock Trust (comprising, respectively, the SAFECO Growth Fund,
SAFECO Equity Fund, SAFECO Income Fund, SAFECO Northwest Fund, SAFECO
International Stock Fund, SAFECO Balanced Fund, SAFECO Small Company Stock Fund,
and SAFECO U.S. Value Fund), the SAFECO Taxable Bond Trust (comprising,
respectfully, the SAFECO Intermediate-Term U.S. Treasury Fund and SAFECO
High-Yield Bond Fund), the SAFECO Managed Bond Trust (comprising the SAFECO
Managed Bond Fund), the SAFECO Tax-Exempt Bond Trust (comprising, respectively,
the SAFECO Municipal Bond Fund, SAFECO California Tax-Free Income Fund, and
SAFECO Washington State Municipal Bond Fund), and the SAFECO Money Market Trust
(comprising the SAFECO Money Market Fund) as of December 31, 1997, and the
related statements of operations, the statements of changes in net assets, and
the financial highlights for each of the periods indicated therein. These
financial statements and financial highlights are the responsibility of the
Trusts' management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.
   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned as of December 31, 1997, by correspondence with the custodians
and brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

of the respective Funds of the SAFECO Common Stock Trust, the SAFECO Taxable
Bond Trust, the SAFECO Managed Bond Trust, the SAFECO Tax-Exempt Bond Trust, and
the SAFECO Money Market Trust as listed above at December 31, 1997, the results
of their operations, the changes in their net assets, and financial highlights
for each of the periods indicated therein, in conformity with generally accepted
accounting principles.
