   Whether SAFECO Growth Fund led or lagged in the latest quarter and year
depends on how you look at it. The Fund, which is about 65% small stocks,
underperformed the average growth fund, but outperformed the small stock group.
   The Fund returned 19.58%* for Class A shares and 19.29%* for Class B shares
for the quarter and 4.47%* for Class A shares and 3.38%* for Class B shares for
the year. The average small-cap fund returned 19.12% and -0.33% for the quarter
and year, according to Lipper, Inc. The average growth fund, which favors
larger, more expensive issues than we do, returned 22.61% for the quarter and

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.

22.86% for the year, as mentioned by Lipper, Inc.
   A comparison of the S&P 500 (a proxy for larger stocks) and the Russell 2000
(a small cap index) shows how differently the large and small cap categories
performed. For 1998, the small cap indicator was down 3.45% while, the S&P 500
gained 28.58%. Growth Fund's performance diverges from both indicators because
its holdings are not selected to match either index, but for value and
appreciation potential.
 
   Broadcasting remains our largest sector. I bought more Chancellor when it
declined on fears that recession would lower advertising revenue. In reality,
radio is benefiting by a strong U.S. economy and gaining market share from other
media.
   When Conseco (Insurance) fell during the third quarter, insiders recognized
the value and snatched up shares. I think the market soon will too. Conseco is
positioned to increase profitability and pick up market share.

                      REPORT FROM THE GROWTH FUND MANAGER
 
   NCO Group climbed into our top ten. It's the second largest, and only public,
bad-debt collector in the nation. This is partly a rough-times play. Our economy
is increasingly fueled by debt, and that makes bill collection a growth
industry.
   All told, health care counts for 14.3% of net assets. I like the defensive
nature and demographic positives of health care. Beckman Coulter, new to our top
ten, supplies capital equipment to the medical industry.
   With 70% of its sales in Japan, Nu Skin Enterprises was hurt by a weak yen.
This company direct-markets personal products outside of the U.S. and has great
potential in emerging economies where multi-level marketing is more accepted.
   Family Golf Centers was punished for buying ice rinks. While this will lessen
its seasonality, the company now has to prove they can turn around ice rinks as
well as they have driving ranges. I think they can.

   Except for radio, all the stocks we've discussed are selling at a discount in
a market where large growth stocks are selling at tremendous premiums. As
earnings slow, I predict investors will become increasingly price conscious and
less likely to pay top dollar.
   Because I look for a share price that is a fraction of a company's growth
rate, most of the stocks we own are already marked down. If they outperform even
a little--especially the small ones--the very investors who abandoned them may
rush back in. And, theoretically, price will follow demand.
   The primary reason the Growth Fund has historically held smaller company
stocks is that they offer better growth prospects at better valuations than
bigger

   SAFECO Equity Fund beat its Lipper, Inc. peer group for the year and quarter
ended December 31, 1998. The Fund was up 24.77%* for Class A shares and 23.16%*
for Class B shares, for the year. For the fourth quarter, the Fund returned
18.72%* for Class A shares and 18.38%* for Class B shares, compared to 17.79%
for the peer group.
   We again benefited as larger capitalization stocks outperformed smaller
capitalization stocks. The Fund, on average, owns a larger percentage of big
companies than the peer group. Our focus on size, quality and predictability
kept us ahead of the average growth and income 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.

market index at the end of November, but had a poor December as technology
issues, which we own less of than the index, surged. The S&P returned 28.58% for
the year. Most of it, 21.28%, came during the fourth quarter.
   We ended 1998 holding 47 companies. Turnover in the portfolio remained low
and steady, at 32.94%.
   In the last six months, most of the changes in the portfolio have come from
market action, partial sales and additions. During the year I added only seven
new names to our portfolio, and I deleted ten. The changes were made to increase
the overall quality and earnings predictability of the companies in the Fund.
   Alphabetically our new names are Abbott Laboratories, Bestfoods, CitiGroup,
Procter & Gamble, Schlumberger, U.S. Bancorp, and Washington Mutual. The names
we no longer own are: Boeing, Columbia/HCA Healthcare, Echlin, Electronic Data
Systems, First Data, GTE, Houston Industries, Oracle, Pacificare Health Systems
and SmithKline Beecham.
   Only two of those sales came in the last half of the year. I eliminated
Boeing and GTE during the fourth quarter. Boeing was sold because the earnings

prospects for the next several years have deteriorated greatly. In October of
1997, I believed Boeing would overcome its production inefficiencies and the
"Asia effect". When it became clear this wasn't going to happen, I abandoned the
position.
   GTE was eliminated because the Fund also holds Bell Atlantic, the company
acquiring GTE. Owning both positions wasn't prudent. I reduced our position
sizes in Anheuser-Busch and Burlington Northern when the stock prices reached my
near-term targets.
   One new position was added in the last six months: Bestfoods. The company has
reasonable growth prospects and was selling at 22 times estimated 1999's
earnings per share while the S&P 500 sells at 24-25 times.
   In keeping with what I've done in the past, I added to existing holdings when
I liked their price and sold parts of positions when they were on the high side.
   While I added to 18 names during the fourth quarter, two saw their position
sizes increase materially. American International Group and May Department
Stores were trading at 21 times and 16 times estimated 1999 earnings per share,
respectively, when I added to them.
   In the third quarter, I added substantially to Washington Mutual when I
thought it was at a reasonable price/earnings ratio and I sold down Hartford
Financial Services as it had gained steadily to become the second largest
holding in the Fund. I felt, given the Hartford's valuation level and my overall
exposure to financial stocks, that it was prudent to substantially reduce the
position size. Diversified Financial and Banking and Finance companies comprised
9.4% of net assets at year-end.

   We began our walk to quality almost two years ago and so far, we have been
rewarded. Rather than move too quickly and stumble, I intend to keep the same
path and the same pace. It looks, to me, like the road ahead could be rough.

   After a third quarter so painful that it made for a bad year, SAFECO Income
Fund beat its peer funds in the fourth quarter with 14.35%* for Class A shares
and 14.13%* for Class B shares, compared to 13.35% for Lipper, Inc.'s average
for equity income funds. In spite of the fact the Fund outperformed in three of
four quarters, it underperformed significantly for the full year. For 1998, the
Fund returned 5.38%* for Class A shares and 5.03%* for Class B shares, compared
to the peer group's 10.89% and the S&P 500's 28.58%.

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.

concentrated the Fund on solid businesses with lower-price earnings ratios. I
had avoided Asian exposure and held convertibles to lend stability in the event
of a correction. This conservatism didn't work the way I planned. Small
companies (18 to 20% of assets at the time) grossly underperformed. Convertibles
(about 28% of the portfolio) suffered as spreads to treasuries widened.
Meanwhile our radio stocks behaved as if they were in a recession and without
advertisers.
   We began the fourth quarter holding the same fine companies, and, they came
back to reward us for staying. My investing style, the strong fundamentals of
our companies and the solid underpinnings of the U.S. economy did not change.
The only thing that changed was the markets' psychology.
   Technology was very strong and our higher-than-the-average-equity-income-fund
weighting (about 15%) helped us outperform. So did the recovery of radio stocks
and the fact that small stocks and convertibles moved off their lows.
   During the fourth quarter I made a concerted effort to realize losses and to
increase the Fund's equity sensitivity. Several convertible security positions
were

eliminated (as well as a couple of stocks where the business fundamentals had
become uncertain). Our allocation to convertibles declined from 28% of net
assets to about 23% in the fourth quarter. Family Golf Centers was one of the
convertible positions I sold down and Conseco was one of the equity positions I
increased.
   Only two totally new positions were added to the portfolio: PepsiCo, which
was purchased as Anheuser-Busch was sold, and Equity Residential Properties, an
apartment REIT (real estate investment trust). Our allocation to real estate was
7.6% of net assets at year end. I like this sector as it is cheap and, I think,
poised to come back. Furthermore, REITs offer an attractive combination of yield
and dividend growth.
   Looking to 1999, I feel some discomfort about the stock market. Earnings of
the S&P 500 companies continue to falter and the Index is selling at lofty
levels by any historical measure. The Fund is currently concentrated in solid
businesses with lower-price earnings ratios and little Asian exposure. I believe
our top ten companies have solid fundamentals and room to appreciate. So do the
smaller companies and convertibles we own, these sectors have just begun to
recover. I think small and mid-cap companies will outperform in 1999 for two
reasons. Firstly, the low valuations of these stocks. Secondly, they stand a
strong chance of providing better relative earnings growth than the big stocks.

   The fourth quarter marked the ninth out of the past eleven quarters that the
Fund has beaten the equity-income category. While I have some concerns about the
stock market, my confidence is bolstered by the Fund's persistent positive
performance relative to our peers.

   We ended a lousy year with a good fourth quarter. In it, SAFECO Northwest
Fund began recovering from the four blows dealt us earlier in the year: Boeing,
Asia, small caps and value investing.
   For the quarter, the Fund returned 20.88%* for Class A shares and 20.74%* for
Class B shares. For the year, we eked out 2.87%* for Class A shares and 2.37%*
for Class B shares compared to 22.86%, the Lipper, Inc. average for growth
funds. We also underperformed the WM Group Northwest 50 Index, which returned
32.87% for the year. The Fund was invested less in technology than the index and

* The Fund's 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 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.

caused the Fund to underperform as technology carried the region.
 
   While our region benefited by technology, it suffered from the Asian debacle
more than any other. And therein lies the explanation for 75% of the Fund's poor
annual performance when compared to national growth funds.
   The other part of the explanation is that 47% of our holdings are small caps,
which as a sector more than disappointed investors. A perceived crisis in
liquidity, a subsequent flight to "quality" and tax-loss selling sent small
caps, as measured by the Russell 2000 Index, tumbling 20.50% in the third
quarter. In the Fourth quarter, small caps rallied, contributing to the Fund's
good quarter.
   We would have had an even better fourth quarter if we'd owned more of the ten
stocks that accounted for so much of the S&P 500's 1998 gain. As it is, we own
two of them: Microsoft and Intel.
   As with Intel, I am willing to go outside the Northwest to increase
weightings in areas where growth funds tend to concentrate--technology, consumer

                     REPORT FROM THE NORTHWEST FUND MANAGER
 
staples, healthcare--and where the Northwest seems to be underrepresented. For
example, I took a position in American Home Products, which has controlling
interest in Immunex, a Seattle biotechnology company. At year-end the Fund was
15.4% invested outside the Northwest. We are allowed to invest up to 35% of
assets outside the region.
   Costco and Starbucks were big winners for both the quarter and year. I see
these two, and Microsoft, as core holdings for us, as they are non-cyclical
stocks with the capacity to keep growing. Rather than keep cyclicals, such as
Alaska Airlines and Weyerhaeuser as core holdings, I try to capture their upward
cycle.
   Boeing had no upside in 1998. I had cut it back to just over 2% by year-end.
(At this writing it has been sold out of the portfolio.) Boeing's pending
layoffs are already reflected in the stocks we own that will be most affected
(regional banks). Ninety percent of our companies are not primarily tied to the
Northwest's economy but to the national and international economies, including
Asia.

   I have a sense that the Asian situation is starting to stabilize. Northwest
stocks with exposure to Asia declined early in the crisis and could come back
early in the recovery. For example, Expeditors International, the freight
forwarder, fell 37% in the third quarter, despite the fact it historically
outperforms when imports do well. Schnitzer Steel also fell 37% as one-third of
its business is scrap export to the Pacific Rim.
   While published outlooks for the Northwest economy are darker than they have
been, don't let the headlines scare you. I believe the Fund has absorbed much of
the aftermath of Asia, and most of Boeing's impact. And even though the region
is slowing down, we don't expect it to underperform the national economy. Beyond
2000, I believe it will outperform again.

    The SAFECO International Fund returned 13.68%* for Class A shares and
12.66%* for Class B shares for the year and 18.93%* for Class A shares and
18.63%* for Class B shares for the quarter. The average international fund
returned 13.02% for the year and 16.43% in the fourth quarter according to
Lipper, Inc. For the year, the EAFE Index returned 18.23%.
    For all of 1998, stocks in the Growth in Telecommunications theme were the
largest contributors to the portfolio's performance. Notwithstanding the turmoil
in global capital markets during the third quarter, financial stocks in Growth
in Personal Savings Products also added significant value to the portfolio, as
did the pharmaceutical stocks in Healthcare Needs.

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 INTERNATIONAL STOCK FUND MANAGER
 
    Most of the portfolio's negative performance came from stocks either quoted
in, or with exposure, to Asia. The portfolio's hedging program also detracted
value, mostly as a result of renewed strength in the yen, which we believe
remains overvalued, given the underlying weaknesses in the Japanese economy.
    The most notable performers among our telecommunications stocks were
Netherlands-quoted KPN which announced a joint venture to create Europe's
biggest internet network and Alcatel Alsthom. Alcatel climbed on by acquisitions
in Europe, restructuring plans and news that, with Fujitsu, it will supply the
trans-Pacific cable link between Australia and the U.S.
    Stocks in Positive Banking Environment, which had been at the eye of the
storm during the third quarter turmoil, strengthened significantly as 1998 wound
down.
    Among pharmaceutical stocks the best performers were Takeda Chemical
(Japan), which announced 15% increase in net profits and Novartis. A renewal of
mergers and acquisitions activity

in the European pharmaceutical sector which involved, among others, portfolio
holdings Hoechst and Zeneca also drove prices higher.
    On the whole, global equity markets rebounded strongly since the end of the
third quarter, prompted primarily by the reductions in interest rates which have
occurred in the U.S. and Europe. The general consensus underpinning this
recovery seems to be that the lower interest rates will enable continued
corporate earnings growth.
    We do not subscribe to this theory, given the announcements the companies
themselves are releasing. In recent weeks, from diverse sectors, global
companies such as Boeing, Ericsson, Marks & Spencer's, Proctor & Gamble and
Coca-Cola have all announced earnings slowdowns. Paradoxically, in the face of
bad news, indexes are reaching all-time highs, and some stock prices are rising
to what we consider to be risky valuation levels.
    Economic growth in the UK is likely to slow in 1999 and earnings growth may
be negligible. Much of this, however, may already be priced into the market
given the relative underperformance of UK equities in 1998.
    In Asia, it was a year of upheaval as unemployment skyrocketed, financial
systems came under severe distress and political leaders came under pressure.
While the overall economic environment remains gloomy, the unexpected cut in
U.S. interest rates gave an added stimulus to Asian markets, which were already
benefiting from the stronger yen and increasing investor confidence.
    Nevertheless, there are some positives on the international equity horizon.
The advent of the Euro should be broadly positive for the large pan-European
companies. There has been a resurgence in recent weeks in mergers and
acquisitions activity and this should accelerate in the coming months. Indeed,
given Europe's position in the current economic cycle, the opportunities for
increasing synergies and cutting costs through consolidation are significantly
greater than those in the U.S.
    There continues to be evidence that reform is taking place in Japan, albeit
at the margins. While the government has yet to come through, reform-minded
Japanese corporations have considerable potential for long-term investors. We
will continue to concentrate on European stocks that have the ability to prosper
in the single currency environment and selected companies in Japan.

                              SAFECO BALANCED FUND
                               December 31, 1998

- --------------------------------------------------------------------------------
 
    The SAFECO Balanced Fund returned 9.92%* for Class A shares and 9.79%* for
Class B shares, for the fourth quarter. For the year the Fund returned 12.06%*
for Class A shares and 11.30%* for Class B shares. The average balanced fund
returned 11.32% for the fourth quarter and 13.48% for the year.
    A split benchmark (60% S&P 500 and 40% Lehman Brothers Government/Corporate
Index) returned 12.82% and 20.93% for the quarter and year. We underperformed
the combined index because we are value investors and value stocks
underperformed growth stocks. (On the bond side, the portfolio outperformed, but
not enough to carry the Fund.)

*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 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 BALANCED FUND MANAGERS
 
investing. For example, the Russell 1000 Growth Index was up 37.41% while the
Russell 1000 Value Index posted just 13.21%. This spread in returns is by far
the largest divergence between the two indices in their 20-year history. As
well, a study of the S&P 500 shows that stocks with the loftiest price/earnings
valuations had the best performance.
    The equities of this Fund are selected for value and earnings growth. For
example, we sold our position in Anheuser-Busch and replaced it with PepsiCo,
which we felt was priced at a more compelling valuation based on near-term
restructuring opportunities and long-term earnings prospects. As year-end
approached, we sold Boeing to offset some portfolio gains and sold Sequent
Computer Systems and Unisource Worldwide due to weak near-term fundamentals.
Early in the fourth quarter, we increased the weighting in financials and
technology as price opportunities arose.

    Our strategy in managing the equities in the Fund remains unchanged. We buy
stocks with discount valuation characteristics that have attractive earnings
prospects. The portfolio has a price earnings ratio (P/E) based on 1999
projected earnings of 18.2 compared to the S&P 500's P/E of 25.9. The projected
earnings growth rate for the stocks in our portfolio is higher than that of the
S&P 500. The Fund's equity portfolio is diversified across all major market
sectors.
    This strategy has been employed at SAFECO for many years and has provided
superior returns at lower risk levels over time. We remain confident the value
style will once again return to favor.
    At year-end, the asset allocation of the fund was 63.3% stocks and 36.3%
bonds, while the cash position was 1.3%. We are currently targeting a 60% equity
and 40% fixed-income asset allocation.

    We took some defensive precautions to improve the overall quality and
liquidity of our bond portfolio during the quarter. We reduced our holdings in
smaller corporate bonds, international issues, and triple-B rated securities, in
favor of extremely large, high quality domestic bonds and U.S. Treasuries.
    At year-end, the bond portion of the Fund held 64% of its assets in U.S.
Government obligations, including a 51% weighting in U.S. Treasuries. Portfolio
duration was unchanged at 5.8 years, slightly longer than the 5.6 year duration
of the Lehman Brothers Government/Corporate Index. The average credit quality of
the portfolio improved to AAA.
    Our outlook for 1999 is mixed. While the U.S. economy continues to do well,
it is likely that corporate earnings growth will slow. This reduced earnings
growth, combined with current high valuations, will probably result in a lower
stock market return. The outlook for bonds is more positive, which makes a case
for diversification.

                        SAFECO SMALL COMPANY STOCK FUND
                               December 31, 1998

   SAFECO Small Company Fund had a disappointing fourth quarter and year, which
I attribute, not to stock selection, but to "attributes"--our smaller market
capitalization and the value orientation of the Fund.
   For the fourth quarter 1998, the Fund returned 3.36%* for Class A shares and
3.23%* for Class B shares while the average small company fund gained 19.12%
according to Lipper, Inc. For the year, the Fund was down 21.96%* for Class A
shares and 22.67%* for Class B shares, versus the peer group average of -0.33%.

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 STOCK FUND MANAGER
 
   The Russell 2000 Index returned -3.45% for the year and 16.05% for the
quarter. Our underperformance for the year and our lag during the fourth quarter
recovery, is not due to problems with any particular stock. It was due to the
type of stocks I favored--smaller and cheaper than those held by my peers.
   While the Fund held strong companies during the quarter, their stocks were
largely ignored and or beaten without justification. Tiny, cheap Styling
Technology was one such company. It declined 50% in the fourth quarter in a
rapidly recovering market. Styling's business is healthy and it remains the only
consolidator in the salon products industry. At quarter end, the stock was
trading at a price to earnings ratio of only 5.7 times its 1999 consensus
earnings estimate.
   Regarding market capitalization, a study of the Russell 2000 Index released
by the Frank Russell Company examined price performance by market cap decile.
Returns consistently worsened as stocks got smaller, from the largest 10% to the
smallest 10% of the

Index. The Fund's average market cap is well below the average market cap of the
Russell 2000 Index, and thus the Fund's holdings suffered for their size.
   The smallest companies are out of favor because of their perceived
illiquidity. Investors are currently paying a premium for size and trading ease
as is evidenced by the outperformance of larger stocks, not just within the
Russell 2000, but between the Russell 2000 and the S&P 500. (The Russell 2000
returned -3.45% for the year. The S&P 500 gained 28.58%.) Unfortunately, the
smallest companies are still suffering on lingering liquidity fears and the
perception that they are more vulnerable in slow growth environments.
   Adding insult to the injury of being smaller, the average valuation of the
stocks we held was lower than the index and 1998 was a year in which value
stocks sadly underperformed. (The Russell 2000 Growth Index returned 1.23%,
while the Russell 2000 Value index fell 6.45%.)
   At year end, the portfolio's price earnings ratio on forward earnings
estimates was 11 times, as compared to the S&P Small Cap 600 index at 17.6 times
and the S&P 500 at 25 times.

Medium: ($250 - $750 million)             28%

Cash and Other:                           12%
</TABLE>
 
   The Fund's PEG ratio (price/ earnings to the companies' forward growth rate)
is 0.50 times. This compares to 0.90 times for the S&P Small Cap 600 and over
5.00 times for the S&P 500.
   Given the difficult environment for small cap value, I eliminated positions
in stocks I had less confidence in. This trimmed the number of names owned to 32
and increased the weightings of those positions, although none are egregiously
large. Nine of the top ten holdings earned a positive return in the latest
quarter.
   I held onto companies I believe in and think are bargain values. I remain
confident the value I see will ultimately be perceived by other investors and
reflected in a higher net asset value for the Fund. I will continually evaluate
our holdings and won't sell our small cap value stocks unless I believe the
reasons to own them are no longer valid. What I will do is gradually increase
the market capitalization of the portfolio by adding names at the larger end of
our range.

                             SAFECO U.S. VALUE FUND
                               December 31, 1998

   During the fourth quarter, the U.S. Value Fund returned 15.81%* for Class A
shares and 15.84%* for Class B shares, underperforming the Russell 1000 Value
Index's return of 16.60%, and the S&P 500's 21.28%. Returning 11.79%* for Class
A shares and 11.18%* for Class B shares for the year, the Fund underperformed
the 15.61%, Lipper, Inc.'s average for growth & income funds, and the S&P 500's
28.58%.
   The Fund lagged because low-priced stocks lagged high-priced ones, and as
value managers, we select from stocks that we have identified as undervalued.
Unfortunately, in the last several years, stocks with the lowest valuations have
had the worst performances.  [PHOTO OF REX BENTLEY]

*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.

                    REPORT FROM THE U.S. VALUE FUND MANAGERS
 
   For example, in 1998 the difference in the returns of large capitalization
growth stocks and large capitalization value stocks was over 23%: The Russell
1000 Value Index returned 13.21% for 1998, while the Russell 1000 Growth Index
delivered 37.41%. This is by far the largest divergence between the two indices
in their 20-year history. The next largest spread was 16.6% in 1991, and the
average annual spread between the Russell 1000 Growth Index and the Russell 1000
Value Index, over 20 years, is 8.7%.
 
   The following table further illustrates the divergence of cheap and expensive
stocks. It shows returns for the S&P 500 broken out by price earnings ratios
(P/E); the most-often used valuation for stocks:

underweighting in financial services and consumer cyclicals. We have increased
the Fund's weighting in financials over the past few quarters, as valuations
became more attractive. We remain underweighted in financial services relative
to the value indices and overweighted relative to the S&P 500.
   Our strategy in managing the Fund and our belief in value-style investing
remains unchanged. We will continue to buy stocks with discount value
characteristics that have attractive earnings prospects.
   At year-end, the portfolio had a PE based on 1999 projected earnings of 18.2
compared to the S&P's PE of 25.9. The projected earnings growth rate for the
stocks in our portfolio is higher than the projected growth rate for the S&P
500. This strategy has provided superior returns at lower risk levels over time
and we are confident it will again.
   During the quarter we sold our position in Anheuser-Busch and replaced it
with PepsiCo, which we felt had a more compelling valuation based on near-term
restructuring opportunities and long-term earnings prospects. As year-end
approached, we sold Boeing to offset some portfolio gains and sold Sequent
Computer and Unisource due to weak near-term fundamentals.

   Our outlook for 1999 is mixed. While the U.S. economy continues to do well,
it is likely that corporate earnings growth will slow. This reduced earnings
growth, combined with current high valuations, will probably result in a lower
stock market return than we have recently experienced. We anticipate that a
slowing economy will cause investors to re-evaluate the extreme valuations in
some market sectors. Value oriented equities should once again provide
attractive relative returns.

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.

catalyst for this extraordinary performance was a series of interest rate
easings by the Federal Reserve. Beginning in late September, the Fed eased three
times taking the Fed Funds rate from 5.50% to 4.75% by mid-November. Conspicuous
in this process was the October 15th drop of 25 basis points from 5.25% to 5.00%
which occurred between the Fed's regularly scheduled meetings. This move sent a
signal to the financial markets that the Fed was ready to use monetary policy
proactively to prevent further dislocation in financial markets.
   Spreads-to-Treasuries (differences in yields) for high-yield bonds narrowed
across all ratings categories. The "sweet-spot" from a performance perspective
was the single B category. At year-end, single Bs made up approximately 71% of
the Fund, and this large allocation contributed to the Fund's good relative
performance during the quarter.
   Throughout the year I emphasized larger, more liquid bond issues, which
proved particularly beneficial in August and September, as liquidity became an
increasing concern. I also favored debt from larger, better-capitalized
companies, especially those with public equity that had performed well.
Improving equity pricing gives an issuer an alternative "currency" and a
potential vehicle for deleveraging. Finally, I looked for companies with
primarily domestic businesses. The better performers in the Fund shared some or
all of these traits, and included companies like Qwest Communications, Allied
Waste Industries, and Ball Corp.

                  REPORT FROM THE HIGH-YIELD BOND FUND MANAGER
 
   In the fourth quarter, I added Chancellor Media to the Fund. Chancellor is
engaged in radio and television broadcasting, and outdoor advertising. An active
industry consolidator, Chancellor has the potential to use its increased cash
flow to reduce debt, and achieve a higher investment rating. I also purchased
Hayes Lemmerz, a manufacturer of automotive wheels and brake products. They
supply these products both to the original equipment manufacturers and the
after-market, and command number one or two market positions in most markets
where they compete.

   The Fund ended the year with net assets of just over $84 million invested in
66 companies in 42 industries. My strategy for 1999 will be much like this
year's. I believe the U.S. economy will grow at a slightly slower pace than last
year, and that inflation will remain subdued. I intend to maintain a
well-diversified portfolio that allows investors to participate in the
high-yield 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 INTERMEDIATE-TERM U.S. TREASURY FUND MANAGER
 
performed better than the Index for the full year, and fared worse in the fourth
quarter. As interest rates declined in the first nine months of 1998, prices
moved up faster on the longer duration bonds, such as those held by the Fund. In
the fourth quarter the trend reversed: interest rates rose and the Fund declined
faster than the Index. Our average duration has been similar to, or slightly
longer than, our peers as well.
   Trading activity was light in the fourth quarter. We bought six-month U.S.
Treasury Bills and 10-year U.S. Treasury Notes while maintaining an average
maturity at six years. U.S. Treasury securities comprise 79% of the Fund and
U.S. Government Agency Securities add another 16%.
   We expect the year ahead to be good for bonds, but not as positive as 1998. A
slowing economy, low inflation, and a neutral Federal Reserve provide a strong
foundation for the U.S. bond market. But there are some concerns. While the
consensus of economists has been for a slowdown in the U.S. domestic economy for
at least two quarters, to date there has been little evidence of slowing.
Indeed, economic data released in January point to acceleration in economic
growth. The Fed almost certainly will not ease again as many investors are
hoping and counting on.
                                   HIGHLIGHTS
                        -------------------------------
 
 CURRENT YIELD (30-DAY) CLASS A ......................................... 3.22%
 CURRENT YIELD (30-DAY) CLASS B ......................................... 2.68%
 WEIGHTED AVERAGE MATURITY .......................................... 6.0 YEARS
   The international situation likewise clouds the future. Persistent economic
weakness in Asia could set off another flight to quality and push bond prices
higher. On the other hand, strength in the new European currency, the Euro,
could weaken the dollar and push bond prices lower. We are forecasting a modest
increase in bond prices.
   However, given the renewed strength in the economy, we no longer feel
comfortable with a duration that is 50 percent longer than the comparable index.
If the economy carries interest rates higher and the Fed is unlikely to ease,
we're better to err to the short side. After the end of the quarter, I
restructured the portfolio to bring our average duration in line with Merrill
Lynch's Intermediate-Term Treasury Index.

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.

be attributed to three things. First, the Fund's duration (sensitivity to
interest rates) was somewhat longer than both its peer group and benchmark.
Thus, as interest rates rose approximately 0.25% during the fourth quarter the
Fund lagged. However, being longer allowed the Fund to make greater gains as
rates declined overall, by roughly 1%, for the year.
 
   Second, the portfolio held relatively more of its assets in Treasuries, which
were top bond performers in 1998. This conservative posture worked very well

October until Treasuries came down off their flight-to-quality highs, and credit
sensitive instruments--particularly high quality domestic corporate
bonds--outperformed. Third, the Fund's relatively high allocation to mortgage-
backed securities was a drag on relative performance as this sector
underperformed for both the quarter and the year.
   The year 1998 will go down as one of the most volatile bond trading years in
history. At the beginning of the year, the markets were less concerned about the
possible effects of the Asian debacle, and more focused on the possibility of
the Fed raising interest rates. It was smooth sailing until August when Russia
defaulted on its debt and triggered a surge of flight-to-quality buying into
Treasuries. Volatility soared, and spread product (i.e., non-Treasury Bonds)
collapsed. In an effort to support nervous markets, the Fed reduced rates three
times by a total of 75 basis points over a seven-week period, thereby boosting
investor confidence.

                   REPORT FROM THE MANAGED BOND FUND MANAGER
 
   Around October, as market sentiment shifted away from the global Armageddon
scenario, investors began bottom-fishing quality credits. The spread product
tightened sharply, staging one of the most impressive rallies on record, while
U.S. Treasuries lagged.
   Although I am concerned at the pace of spread tightening, I am encouraged by
the return of liquidity to the U.S. credit markets. I expect continued
improvement in spread product relative to U.S. Treasuries. However, as the year
progresses, one, or more, of the many potential problems in the global economy
may spur another flight to U.S. Treasuries. Given that very real possibility, I
took defensive precautions during the fourth quarter. I replaced corporate
bonds, international issues, and triple-B rated securities with U.S. Treasury
obligations and extremely large high-quality domestic corporate bond offerings
to improve our overall portfolio quality and liquidity.
   At year-end, the Fund held 42% of its assets in U.S. Treasury obligations,
24% in Asset-Backed Securities, 17% in high-grade Corporate Bonds, 16% in U.S.
Agency Debentures, and 5% in cash. The portfolio's effective duration was 6.9
years at year end, longer than the duration of the Lehman Brothers
Government/Corporate Bond Index at 5.6 years. The Fund is maintaining an average
credit quality rating of triple-A.
   Going forward, I will continue to use a combination of active duration
management, sector rotation, yield-curve positioning, and credit selection to
keep us well positioned for whatever 1999 may bring.

                                OVERVIEW OF THE
                          SAFECO MUNICIPAL BOND MARKET
                               December 31, 1998

   In a year characterized by excessive volatility in financial markets around
the globe, the municipal bond market was range bound. The yield on long-term
tax-exempt bonds varied by less than 50 basis points (0.5%) from high to low. It
closed 1998 at 5.16%, only 10 basis points (0.1%) lower than it opened the year.
   The fourth quarter was even more uneventful, with long bonds trading in a 25
basis point (.25%) range. While yields on tax-exempts remained virtually
unchanged, long-term U.S. Treasury Bond yields fell, pushing the ratio of
tax-exempt to taxable yields as high as 105% on October 5th . The ratio remained
above 100% for most of fourth quarter, during which 30-year Treasury yields hit
all-time lows.            [PHOTO OF STEPHEN C. BAUER]
 
   The reasons for this unusual relationship in which Treasuries yielded less
than similar length munis were several. Foremost was the demand for Treasuries
(with little regard for yield) from foreign buyers seeking safe haven from their
battered economies, currencies, and financial markets. A second important factor
was that yields available in the muni market, and subsequently demand for muni
bonds, were near 20-year lows. Finally, there was supply. New issue volume was
surprisingly heavy throughout 1998 as strong balance sheets enabled state and
local governments to increase borrowing, and low rates encouraged them to
refinance. Total new issue volume for 1998 was $284 billion, a close second to
the record $292 billion of 1993, and up 29% from 1997.
   Looking forward to 1999 and seeing almost no evidence of an increase in
inflation, it is hard to see what events might conspire to dramatically move
long-term interest rates in either direction. Another international financial
crisis and flight to quality could sharply lower U.S. Treasury yields. But the
duration of such a change could be brief and the effect on other financial
markets, especially municipals, might be nonexistent. I believe 1999 will be
another year of modest change for municipals although they should outperform
government bonds as the ratio of tax-exempt to taxable yields trends toward its
historical range.

                           SAFECO MUNICIPAL BOND FUND
                               December 31, 1998

   SAFECO Municipal Bond Fund returned -0.17%* for Class A shares and -0.27%*
for Class B shares to its peers' 0.09% for the fourth quarter of 1998. For the
full year, the Fund delivered 5.75%* for Class A shares and 5.08%* for Class B
shares to the competition's 5.32%, according to Lipper, Inc. The Fund's
longer-term results are gratifying as well. The Fund's average annual return was
6.03%* for Class A shares and 5.72%* for Class B shares for the five year
 
period and 8.17%* for Class A shares and 8.01%* for Class B shares for the ten
year period.
   The Fund underperformed The Lehman Brothers Long Municipal Bond Index, which
returned 0.28% for the quarter and 6.90% for the year. This underperformance is
standard. It's nearly impossible to beat a bond index because it has no
expenses, no cash and no call features.
   Since yields rose slightly during the fourth quarter, 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.

underperformed its peers over the three-month period. Our longer-than-average
maturity generally results in below-average returns when yields rise and prices
fall. However, it helps us outperform when yields decline. As our one, three,
five and 10-year results attest, our strategy of staying fully invested in long,
deep-discounted bonds has paid off.
   After a year of looking, I found, in December, two opportunities to add yield
to the Fund. The first was the Indiana Development Finance Authority, issuing
bonds on behalf of USX Corporation, the holding company for U.S. Steel and
Marathon Oil. This credit is rated Baa2 by Moody's and BBB- by Standard & Poors
and came at a yield of 5.60% One week later, the Muni Bond Fund bought Vancouver
Housing Authority 5.65%, due 3/1/31, at a discount to yield 5.75%. Although this
issue is non-rated, the credit is sound, backed by the general credit of the
Housing Authority and a first mortgage pledge.
   With the exception of these two issues, which were priced at or near par, I
have emphasized deeper discount bonds during 1998 and I expect to continue that
strategy in 1999. The additional call protection that is provided by deep
discount bonds could prove to be extremely beneficial if yields drop.

                          REPORT FROM THE FUND MANAGER
                     SAFECO CALIFORNIA TAX-FREE INCOME FUND
                               December 31, 1998
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
 
   For the fourth quarter 1998, the SAFECO California Fund returned -0.29%* for
Class A shares and -0.44%* for Class B shares to its peer funds' 0.01%,
according to Lipper, Inc. For the year, the Fund delivered 5.73%* for Class A
shares and 4.98%* for Class B shares to the competition's 5.77%.
   The Fund underperformed the Lehman Brothers Long Municipal Bond Index, which
returned 0.28% for the quarter and 6.90% for the year, but this is standard.
It's nearly impossible to beat a bond index because it has no expenses, no cash
and no call features.
   Since yields rose slightly during the fourth quarter, the Fund underperformed
its peers over the three-month period. Our longer-than-average maturity
generally results in below-average returns when yields rise and prices fall.

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 CALIFORNIA TAX-FREE FUND MANAGER
 
However, it helps us outperform when yields decline. Over the last one, three,
five and 10-years, our strategy of staying fully invested in long, deep-discount
bonds has paid off.
   During 1998 the California Fund grew from $89 million to $114 million and I
carried more cash than I like as I waited for an attractive offering to appear.
I was able to add call protection to the Fund throughout the year by selling par
bonds and buying bonds at the deepest discounts available, but I never did find
any of the lower-rated, higher-yielding bonds at favorable spreads to high
grades that I favor. Perhaps next year. We ended this last one with an average
maturity of 25.3 years and 1.6% cash.

   The SAFECO Washington State Municipal Bond Fund returned 5.36%* for Class A
shares and 4.55%* for Class B shares, while Lipper, Inc.'s average Washington
State Municipal Bond Fund returned 5.78% for the year. For the fourth quarter
the Fund returned -0.35%* for Class A shares and -0.50%* for
                          [PHOTO OF BEVERLY R. DENNY]
Class B shares, while the peer group returned 0.04%. The Fund's longer duration
(sensitivity to interest rates) will typically cause the Fund to lag as rates
increase, and to outperform as rates fall and the market rallies as it did for
the year.

* 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.

month and one-year returns at 0.28% and 6.90%. It's virtually impossible for us
to beat this benchmark, as it is a national index, which has no expenses, cash
holdings nor call features.
   I sold our Seattle Municipal Sewer Bonds in October. In November, I bought
some higher-yielding bonds issued by the Vancouver Housing Authority with a
5.65% coupon at a 5.75% yield. I later sold the Grant County PUDs to raise cash
for the Vancouver Bonds.

   The SAFECO Money Market Fund returned 4.92%* for Class A shares and
4.76%* for Class B shares for the year, while the average money fund's
total return was 4.86%, according to Lipper, Inc. For the quarter ending
December 31, 1998, the Fund's average return was 1.24%* for Class A shares and
1.17%* for Class B shares, which surpassed the peer group's 1.14% return for the
same period.                 [PHOTO OF NAOMI URATA]
 
   The increase in the Fund's yield is attributable to the purchase of one-year,
fixed-rate paper, resulting in an average maturity as long as 87 days during the
half-year compared to an average of 60 days for other funds in its peer group.
The longer maturity paper enabled the Fund to maintain yield as the Federal
Funds rate fell from 5.25% to 4.75%. The Federal Reserve lowered the rate twice
during the quarter. Short-term rates remain inverted from one day out to 270
days, so that one-day rates are at higher levels than 270-day rates. This
indicates that the market believes that future rates will be lower.
   The Federal Reserve's easing mode was prompted by a slowing global economy,
the Asian crisis and declining liquidity in the financial markets. The
likelihood of further rate cuts is possible depending on the pace of growth of
the global economy, the financial health of emerging markets, and inflation. The
possibility exists that instead of slowing further, the U.S. economy could
continue growing at a healthy pace leading to higher rates. To hedge against
rising rates, I increased the amount of floating rate paper of corporations
priced off of one month LIBOR, the London Inter-bank Borrowing Rate. LIBOR
floaters trade cheap to boost the yield on the Fund compared to one-month
commercial paper with comparable credit ratings.
   The most notable occurrence in 1998 was a huge flight to quality. The Fund
served as refuge for investors fleeing markets that are vulnerable to foreign
problems. Cash flow into the Fund was significant and so far, it has stayed. As
I've done in the past, I will work to manage the Fund to be a safe haven for
your

investment dollar in spite of volatile market conditions. I will do this by
buying quality paper subject to careful credit review. I will lock in some
longer-term rates to provide stability and downside protection in case rates
decline, and I will maintain some short maturities in case rates move up. The
shorter maturities will also provide liquidity for your short-term cash needs.

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 International Stock Fund
              SAFECO Balanced 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

                         NOTES TO FINANCIAL STATEMENTS
 
Class (with the exception of the Money Market Fund Advisor Classes) pays a
service fee to the distributor, SAFECO Securities, Inc., 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.
   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.
   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
 
                                     - 99 -

                         NOTES TO FINANCIAL STATEMENTS
 
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

                         NOTES TO FINANCIAL STATEMENTS
 
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.
   ESTIMATES. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amount of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

               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, 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, respectively, the SAFECO High-Yield Bond
Fund, and SAFECO Intermediate-Term U.S. Treasury Fund), the SAFECO Managed Bond
Trust (comprising the 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, respectively, the SAFECO Money Market
Fund) as of December 31, 1998, 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, 1998, 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.

   In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
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, 1998, 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.

                                EURO CONVERSION
 
   Effective January 1, 1999, eleven European countries converted to a common
currency: Austria, Belgium, Finland, France, Germany, Ireland, Italy,
Luxembourg, the Netherlands, Portugal, and Spain. Thus, investments traded in
these markets are now denominated in the new currency-the "Euro". The
combination of these currencies into a single currency presents certain
challenges. However, SAFECO Asset Management and the International Fund's
sub-advisor (Bank of Ireland Asset Management) believe that this economic union
presents greater investment opportunities.
 
                              YEAR 2000 READINESS
 
   Preparing for Year 2000 is a high priority for SAFECO Asset Management and
its parent, SAFECO Corporation. A corporate-wide Year 2000 team has been active
for an extended period of time, and has devoted considerable resources to help
achieve Year 2000 readiness. SAFECO Asset Management Company does not anticipate
that Year 2000-related issues will have a material impact on its ability to
continue to provide the Funds with service at current levels. Although SAFECO
Asset Management has taken steps to prepare for Year 2000, it could be
negatively impacted by what its business partners have done or have failed to
do.
   Likewise, Year 2000 poses risks to each of the companies in the Funds'
investment portfolio. Thus, portfolio managers consider Year 2000 readiness as
one of the many factors in making an investment decision. Year 2000 also poses
potential risks to worldwide markets and economies.
