     The Intermediate-Term U.S. Treasury Fund beat its peer funds and benchmark
index for the quarter, six months and year ending June 30, 1998.

     For the quarter, the Fund returned 2.06%, compared to 1.83% for the Merrill
Lynch Intermediate-Term Treasury Index. The six-month returns were 3.55% for the
Fund versus 3.41% for the index. For the 12 months, it was Fund 9.94% versus
8.45% index. For further comparison, the average intermediate-term U.S. Treasury
fund returned 2.05%, 3.44% and 9.55% for the three-, six- and 12-month periods,
according to Lipper Analytical Services, Inc.

     The Fund outperformed its benchmark index because its average maturity at
6.0 years is longer than the index at 3.7 years. During a period of declining
interest rates, which we have experienced, longer maturities perform better,
everything else being equal. The Fund was also overweighted in U.S. agencies,
which outperformed, compared to its benchmark index in June. On June 30, the

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. 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.

had 24% of assets invested in agency securities, while the index had 16%.

     The economic environment for bonds has been quite good for the last year.
While the strength in the economy has been worrisome for the bond market, the
moderate rate of price inflation has been just the tonic to keep the bond bears
in check. Problems in Asia, along with good news in inflation, have caused the
Federal Reserve Board (Fed) to be more cautious than they might normally be in
the face of such a strong economy. The Fed has made no move to change interest
rates since March 1997.

     The focus of economic problems in Asia shifted to Japan in the second
quarter of 1998. As concerns about Japan grew, the yen weakened against the
dollar and prompted a flight to quality, with many foreigners abandoning their
Asian issues and buying U.S. Treasury securities as a safe haven. We experienced
a bond market rally--especially in the benchmark 30-year treasury--which
had little to do with U.S. economic fundamentals.

     The mandate of the Intermediate-Term U.S. Treasury Fund is to buy U.S. 
Treasury securities with maturities between three and 10 years. The primary 
tool I have to distinguish this Fund from the index and its peers is setting 
the average maturity.

     We believe the United States is in the middle of a long-term secular 
decline in interest rates. While interest rates may rise and fall as dictated 
by the business cycle, the general trend is down. For that reason, we want to 
maintain the average maturity of the Fund longer than the benchmark index and 
benefit from the better performance of longer bonds.

     Trading in the Fund has been minimal and has focused on maintaining an 
average maturity in the range of 6 to 6.5 years. We have also modestly 
increased the weighting in U.S. agencies. That paper now provides relatively 
more yield as the spring's strong rally in U.S. Treasuries caused their 
yields to fall.

     While the long-term outlook is for lower rates, the near-term is more 
problematical. For more than a year, we have enjoyed a near perfect bond 
environment, with the economy strong and price inflation subdued. The 
strength in the economy has continued longer than most forecasters 
envisioned, and we are seeing some signs of inflation accelerating. The 
Federal Reserve Board, to head off inflation, may be forced to begin raising 
interest rates at the end of this year or

early in 1999. We believe we can get through this period without the Fed acting,
but concede there is a nearly 50% probability they will begin raising rates by
February 1999.

     If the Fed does move to raise rates, I would expect to significantly
shorten the average maturity of the portfolio to be more closely aligned with
the benchmark index.

     For the quarter ended June 30, 1998, the SAFECO GNMA Fund returned 1.89%
versus 1.71% for the peer group of GNMA funds, according to Lipper Analytical
Services, Inc. For the six and 12 months, the Fund returned 3.33% and 8.74%
compared to the peer group's 3.18% and 8.59%.  The Merrill Lynch GNMA index
posted 3.47% and 8.98% for the six- and 12-month periods.

     Our underperformance compared to the index is due to expenses, of which the
index has none. I attribute our outperformance of other GNMA funds to timely
trading (moving out of bonds that were susceptible to prepayments) and having
slightly longer bonds than my peers.

     I felt interest rates would fall this year, so I completed (and will
continue to complete) trades to capitalize on this stance. My trading activity
was quite heavy and consisted of selling more callable paper, which I felt was
trading too expensively. I replaced seasoned paper and many of the premium
coupon (8.5%+) bonds with more liquid and lower interest rate (6%-7%) bonds or
call-protected Collateralized Mortgage Obligations (CMOs). I also kept the cash
balance to a minimum.

     At June 30, the portfolio had a decidedly longer average maturity

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. 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 lower coupon emphasis. Our duration and weighted average maturity were 3.3
and 6.8 years versus 2.2 and 5.2 years for the indices. The Fund's average
coupon and projected yield were 7% and 6.44% versus 7.2% and 6.57%.
Approximately 64% of the portfolio consisted of GNMAs with the balance in CMOs,
Federal National Mortgage Association (FNMA) or Federal Home Loan Mortgage
Company (FHLMC) obligations.

     The bond market rally continued as interest rates fell during the past
quarter. The Asian financial crisis was a major impetus behind the recent drop
in rates for many reasons. First, overseas buyers have been buying U.S. Treasury
securities as protection against their own falling currencies. Second, the
well-publicized weakness in the Asian economies has made bond market
participants more comfortable with a slowing domestic economy. And, that
slowdown has fueled domestic demand for U.S. bonds. Finally, inflation fears and
the need for the Federal Reserve to raise rates abated, further supporting the
bond markets. 

     Regarding the mortgage-backed securities market, prepayment fears and
strong demand have been the year's dominant themes. Many Wall Street economists
feel that we have seen the greatest surge in homeowner refinancing. This means
the mortgage-backed securities most susceptible to early prepayments will start
to do better, although I don't feel they represent good value yet.  

     The second driver in the mortgage-backed market was the overwhelming buy
programs put into place by the two main issuers. FHLMC and FNMA, by some
estimates, have purchased 60%-75% of new MBS issuance this year and show little
pullback for the balance of the year. Add to this demand from domestic
participants who are buying mortgage-backs for their attractive spread over U.S.
Treasury securities, and the mortgage market has done very well in this rally
(except those securities susceptible to early refinance or call risks).

     It was no surprise that the longer and more call-protected bonds generally
outperformed. In looking at the various mortgage-back sectors, the major
difference

was whether a bond was collateralized with low interest rate (less-callable
discount pools) or high interest rate (more-callable premiums) mortgages.
Discount and longer-maturity securities (6%-7% 30-year mortgages) out-performed
shorter and premium-backed securities (five-year balloons and bonds with 8.5%
and above coupons) by a full percentage point.

     The portfolio is currently structured with this combination--a decidedly
longer average maturity and lower-coupon emphasis. I will change that formula
as market conditions dictate, but as long as our outlook for rates stays
favorable, I am happy to hold this bullish stance.

     Year to date the SAFECO High-Yield Bond Fund returned 4.37% as compared to
a 4.40% average return for the Lipper Analytical Services, Inc. High Current
Yield Funds group and 4.58% for the Merrill Lynch High-Yield Master Index. For
the year ended June 30, 1998, the Fund returned 11.40% while the peer group

groups, largely because of the well-diversified nature of our holdings.

the change in market conditions, including a significant deceleration in cash
flowing into high-yield mutual funds beginning in late April, an uptick in the
Moody's default rate over the three months between March to May from 2.18% to
2.53%, indicating an increase in the riskiness of

*    The Fund's inception was September 7, 1988. Graph and average annual return
     comparison begins September 30, 1988.


The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

the market, and continued concerns about Asia's woes, and how this will impact
the domestic U.S. economy. All of these factors contributed to investors
demanding more compensation (yield) for owning "junk" bonds, which in turn led
to lower prices overall.

     I have emphasized domestically-oriented companies in my purchases for the
Fund during the first half of the year. The strength in the U.S. economy is
currently coming from domestic consumption, particularly consumers. At the same
time, U.S. exporters are struggling, and our trade deficit is widening.
Companies such as Ziff-Davis, Niagara Mohawk Power, 21st Century Telecom and
Level 3 Communications should do well in this environment, and are among the
names added to the portfolio since year-end.

     Ziff-Davis is the largest technology publisher in the country (PC MAGAZINE,
PC WEEK, and COMPUTER SHOPPER are among the numerous titles they produce). In
addition, the company also produces trade shows and conferences worldwide, among
them the Comdex computer events. They are involved in

other media as well, and are currently developing a cable channel aimed at
computer users, and an Internet web site.

     21st Century is a cable and telecommunications provider targeting the
high-density, multi-dwelling units in the Chicago metropolitan area. They will
provide residents and small businesses with a bundled offering of phone services
in addition to Internet access and cable television. Level 3 is building a
nationwide "Internet-Protocol" (IP) based telephony network that will deliver
voice and data using IP-packet switched technology. Such networks provide cost
savings, additional accessibility, and technological efficiencies.

     Niagara Mohawk is an electric utility serving upstate New York. The company
is an improving credit story and is positioned well for the deregulated
electricity market evolving in its service territory over the next two years.
Niagara is selling their generating assets and will become a low-risk
distributor of electricity.

     I sold holdings in United Refining, PhoneTel Technologies, and
Gorges/Quick-to-Fix Foods during the quarter because of poor operating
performance, and unfavorable outlooks. Over time, each of these names has seen
leverage increase and cash flow deteriorate.I felt in each case that the high
degree of downside risk warranted our exiting the bonds.

     In my last letter to you, I said that I was cautiously optimistic about the
high-yield market. The same can be said today. In the current economic
environment, credit selection, always an important component of my job, will
take on even greater importance. I will continue to look for companies with good
earnings and cash-flow prospects and strong management teams. Thank you for your
continued interest in the SAFECO High-Yield Bond Fund.

     The SAFECO Managed Bond Fund outperformed its peer funds for the quarter,
six and 12 months ending June 30, 1998. The Fund returned 2.47% for the quarter
compared to 2.05% for the average intermediate investment grade debt fund
according to Lipper Analytical Services, Inc.  The six- and 12-month comparisons
are 3.98% versus 3.61% and 10.43% versus 9.42%, respectively. The Fund's
benchmark index, the Lehman Brothers Government/Corporate Bond Index, which
incurs no fees or expenses, returned 2.61%, 4.17%, and 11.28% for the quarter,
six and 12 months ending June 30, 1998.

     Last year, I made some strategic changes to increase the Fund's
competitiveness, adopting a more balanced approach. I limited the range in which
the portfolio's average maturity would be allowed to fluctuate and concentrated
my efforts on creating additional value through sector rotation, yield curve
positioning and credit selection.

    The market environment over the last 12 months has been particularly 
favorable towards

*    The Fund's inception was June 25, 1992. Graph and average annual return
     comparison begins February 28, 1994 (initial public offering).

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. 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.

               1 AAA: 76%

fixed-income securities. Inflation is low and shows no signs of accelerating.
The economy, which grew very rapidly during the first quarter, is showing
welcome signs of moderation due to the continuing Asian economic crisis. The
Federal Reserve, which has not changed the Fed Funds Rate since March 1997, is
likely to remain on hold for the next several months, at least. And, the growing
federal budget surplus is shrinking the available supply of U.S. Treasury Bonds,
causing them to richen.

     The objective of the Managed Bond Fund is to provide as high a level of
total return as is consistent with relative stability of capital through the
purchase of investment-grade debt securities. Preservation of capital is in part
achieved by the Fund's mandate to maintain a 50% weighting in U.S. government
securities. The Fund makes modest changes in its average maturity in response to
interest rate trends and further distinguishes itself from its index and its
peers through selection.

     During the quarter, we moved portions of the portfolio into and out of
investment-grade corporate bonds as this sector cheapened, richened and
cheapened again relative to U.S. Treasuries. We sold some government and
corporate holdings in the very rich 10-year maturity sector of the yield curve
and bought a higher-yielding combination of securities with maturities of two
and 20 years. Finally, we concentrated our holding in issues insulated from the
problems in Asia, such as U.S. Treasuries and agency mortgage-backed securities
and notes.

     At quarter end, the Fund held 47% of its assets in U.S. Treasury
obligations, 21% in high-grade corporate bonds, 20% in mortgage-backed
securities, 1% in U.S. agency debentures, and 7% in AAA asset-backed securities.
The portfolio's effective duration was 5.7 years on June 30, 1998, slightly
longer than the duration of the Lehman Brothers Government/Corporate Bond Index
at 5.5 years.

     The wild card for the fixed-income markets is the continuing Asian economic
crisis. If the crisis continues to worsen, U.S. economic growth could be
adversely affected. Under this scenario,

U.S. Treasuries will increase in value due to a flight to quality from global
investors, diminished inflationary pressures, and the perception that the next
Fed move will be to lower interest rates. Corporate bonds would underperform
Treasuries as earnings come under increased pressure. If the Asian economic
crisis abates, U.S. economic growth could re-accelerate, increasing inflationary
pressures and the likelihood of a Fed tightening.  Under this scenario, U.S.
Treasuries would decrease in value and corporate bonds would outperform. We will
watch the world economy closely and invest accordingly.

     The municipal bond market was little changed for the quarter and six months
ending June 30, 1998, and total returns were modest for both periods.

     In a flat market, the three keys to performance are: 1. staying fully
invested since bonds yield more than money market instruments; 2. holding the
longest bonds available because longer bonds yield more than shorter ones; and
3. buying lower-quality bonds because lower-rated bonds yield more than
higher-rated ones. I have consistently practiced the first two strategies, but I
am reluctant to downgrade quality. The meager additional yields that
lower-quality bonds currently offer don't seem worth the additional risk.
Fortunately, two out of three has been good enough to produce good results.

     Over the last six months, long-term municipal yields fluctuated only
slightly to end the period at 5.22%. The taxable bond market rallied much more
aggressively and long Treasury yields fell to 5.63% on June 30. (On June 15, the
U.S .Treasury 30-year bond closed at a yield of 5.57%, the lowest yield in the
18-year history of the long-term government bond.)

     The underperformance by the tax-exempt market caused the ratio of
tax-exempt to taxable bond yields to rise to 93%. This means munis currently pay
on a tax-free basis 93% of what a similar-length taxable treasury bond yields.
This is the highest ratio since 1995 and compares to 84% one year ago.

     There are two reasons for the extraordinary cheapness of the muni market:
low absolute yields and heavy new issue supply. Yields near 25-year lows,
coupled with the record-high stock market returns, have created little demand
for long-term muni bonds. On top of this is a new issue market that brought $146
billion in supply over the last six months.

     At the same time, the U.S. Treasury market has enjoyed
increased demand from foreign investors fleeing weakened Asian currencies and
benefited by shrinking supply due to the Federal budget surplus. It is no
surprise that munis are cheap compared to Treasuries. And that creates an
attractive opportunity for high tax bracket bond investors.

     In the extremely stable market that municipal bonds have enjoyed this year,
the only aberration is the relationship between tax-exempt and taxable bonds. As
long as current economic conditions persist, however, I don't see this changing.
Historically, low rates will continue to encourage issuers of new debt while
discouraging investors. The best hope for the municipal market is a correction
in the stock market, which would encourage equity buyers to reevaluate their
asset allocation and to see bonds in a more attractive light.

     For the year ended June 30, 1998, the California Tax-Free Income Fund was
truly the best of the bunch. With a total return of 11.19%, Lipper Analytical
Services, Inc. ranked it first of 100 California tax-exempt funds, which
returned 8.61% on average. (For the 5 and 10 years, the Fund was 5th of 57 funds
and 1st of 30.) For the six months, the Fund returned 2.49% to the peer group's
2.28%.

     The Fund also outperformed the Lehman Brothers Long Municipal Bond Fund
Index, which returned 10.77% for the 12 months. This is due to our strategy of
staying fully invested in long, call-protected bonds.
  
     The California Tax-Free Income Fund had little activity during the last 
six months. I took advantage of the slight downtick in prices in May to do 
two swaps in order to partially offset gains taken earlier this year.

                            REPORT FROM THE FUND MANAGER
                             SAFECO MUNICIPAL BOND FUND
                                   June 30, 1998

     The SAFECO Municipal Bond Fund returned 2.90% for the six months and 10.53%
for the 12 months ended June 30, 1998, outperforming its peer group's 2.26% and
8.39% total returns, according to Lipper Analytical Services, Inc. Lipper's
total return ranking of general municipal bond funds placed the SAFECO Fund at
7th of 233 funds for the one year, 16th of 124 funds for the five years and 12th
of 70 funds for the 10 years ended June 30, 1998.

     The Fund slightly under-performed the 10.77% posted by the Lehman Brothers
Long Municipal Bond Index, but that is to be expected. It's nearly impossible
for a bond fund to beat a bond index because the index has no expenses, no cash
and no call features. The difference between the performance of the Fund and its
peer group is the better measure of success.

     Activity in the Municipal Bond Fund was directed at attractive new 
issues in the marketplace. Two new positions for the Fund were District of 
Columbia G.O. 5.25%, due 2027 at a yield of 5.39%, and Washington State 
Health Care Facilities

     The SAFECO Washington State Municipal Bond Fund returned 8.96% for the year
ending June 30,1998, outperforming 8.91%, the Lipper Analytical Services, Inc.
average for Washington funds. The Fund also bested its peers for the six months,
returning 2.69% versus the competition's 2.65%.

     The Fund came in below the Lehman Brothers Long Municipal Bond Index return
of 10.77%, which is a national index and not as valid a performance yardstick as
other Washington funds which participate in a limited market that is currently
high-priced with few attractive selections. This is due to a scarcity of long
local bonds, high demand and the type of deals coming to market. Further skewing
the comparison is the fact that a bond index has no expenses, no cash and no
call features.

     The Fund had a large inflow of cash (about 5 percent of net assets) at the
end of the first quarter. I bought Spokane General Obligation (GOs) bonds on
March 23. Unfortunately, Murphy's Law

*    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 the Fund to
a hypothetical investment in a relevant market index. 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.

applied, and the money left in early April, necessitating the sale of the
Whatcom GOs. In May, the Fund received another large inflow. I bought Seattle
Water System Revenue bonds, and a new issue of Seattle Wastewater bonds came to
market. Neither one was cheap, but preferable to money market rates.  Both
Seattle bonds have good structure with 5% coupons and 2027 maturities that
extend the Fund's duration.

     As of June 15, the Fund may invest in bonds subject to the Alternative
Minimum Tax (AMT).  As always, I will continue to look for long, discount bonds
that represent value in the market. With a longer duration, the Fund should
outperform its peer Washington Funds during market rallies when interest rates
drop.

     For the year ending June 30, 1998, the SAFECO Intermediate-Term 
Municipal Bond Fund returned 6.72%, compared to 6.69% for the peer group 
defined by Lipper Analytical Services, Inc., and 7.34% for the Lehman 7-Year 
Municipal Bond Index. For the year to date, the Fund returned 1.76% while its 
peers and the index returned 2.05% and 2.32%, respectively.

     Bond portfolios typically underperform bond indexes because indexes are
"paper" portfolios with no expenses, no cash and no call features. The
difference in the performance of the Fund and its peer group is the better
measure of success.

     After starting the year with a brief uptick, the intermediate municipal
bond market has traded in a narrow range, and there are no clear signals that
anything else is on the horizon. Cash flow into municipal bonds has been
lacking, and activity in the Fund was very limited. I did only one trade during
the quarter,

*    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 the Fund to
a hypothetical investment in a relevant market index. 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.

a purchase of $300,000 par of Maine Municipal Bond Bank FSA insured 5% due
11/01/09 at a yield of 4.87%.

     In recent quarters, I have actually sold more securities than I have
purchased. The Fund has, therefore, shortened in maturity and duration which
takes us out of our normal "longer" style and hurts us in performance. I have
resisted doing many swaps to extend maturity, as this would subject our
shareholders to capital gains. However, I am taking another look at this. Taking
a moderate amount of capital gains is not a terrible price to pay to better
structure the portfolio.

     Returning 10.14% for the 12 months ended June 30, 1998, while the average
insured muni returned 7.99%, the SAFECO Insured Municipal Bond Fund was 2nd of
the 51 insured tax-exempt funds tracked by Lipper Analytical Services, Inc. (For
the three and five years, the Fund was 2nd of 45 funds and 4th of 28 funds.)
For the six months, the Fund returned 2.44% to the peer group's 2.05%.

     The Fund underperformed the Lehman Long Insured Municipal Bond Index, which
returned 10.89% for the 12 months. 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. Again, the difference in the performance of the Fund and its
competitors is the better measure of success.

   The Insured Municipal Bond Fund continued its program of swapping to improve
call protection and also bought three new issues. The ability to protect our
portfolio from being called and refinanced at almost no cost continues to be an
irresistibly attractive combination.

*    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 the Fund to
a hypothetical investment in a relevant market index. 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 FUND MANAGER
                              SAFECO MONEY MARKET FUND
                                   June 30, 1998

     In the 12-month period ending June 30, 1998, the SAFECO Money Market Fund's
total return was 4.97%, slightly higher than the average money fund return of
4.96%, as calculated by Lipper Analytical Services, Inc.  The Money Market
Fund's return was very attractive compared to the Consumer Price Index, which
rose 1.68% for the 12 months ending June 30, 1998.

     For the six months, the Fund returned 2.44% compared to its peer funds'
return of 2.42%, according to Lipper Analytical Services, Inc.

     Interest rates from 1 to 120 days remained inverted over the first half of
the year (the one-day rate was more than the 120-day rate), reflecting a belief
that the Federal Reserve will not change the Federal Funds rate in the near
term. From 120 days out to one year, yields climbed sharply, reflecting the
possibility that the Fed may take action toward the end of the year.

     It appears that the Fed will hold rates steady for the third quarter, but
may increase rates slightly toward the end of the year if growth continues at a
high pace. On the one hand, the Asian crisis is expected to slow the Gross
Domestic Product growth from 5.4% in the first quarter to about 1.2% due to a
deterioration in trade and a reduction in inventories. On the other hand,
consumer spending remains very strong, and we see a modest pickup in consumer
prices, especially medical care.

     As a result, I have been buying securities with short maturities out to 30
days and long securities in the one-year area.  This lowered the average
maturity of the Fund from 83 days on December 31, 1997 to 53 days on June 30,
1998. As the one-year pieces mature, I plan to buy more, although the yields are
lower now than when I first started buying them a year ago.

                   REPORT FROM THE MONEY MARKET FUND MANAGER

     I diversify the portfolio so that I have no more than 5% of any one issuer.
I look for issuers with a large amount of commercial paper to distribute or with
slightly lower ratings as their offerings are often cheaper. I added some new
names to the portfolio to take advantage of the attractive overnight rates.  Two
large issuers of overnight securities I added were BP America, a subsidiary of
British Petroleum, and UBS Finance, a financing arm of Union Bank of
Switzerland. I hold a number of floating rate securities with

will help the Fund to respond quickly as their interest rates roll to the higher
levels.

     The SAFECO Tax-Free Money Market started 1998 with a seven-day average 
yield of 3.44% and ended the second quarter at 3.19%. The Fund's performance 
placed it in the 78th percentile for the quarter (29 of 136 funds), the 76th 
percentile year to date (32 of 136), and the 73rd for the one-year period (35 
of 133 funds), according to Lipper Analytical Services, Inc. (For the 5 and 
10 years, the Fund was 35 of 124 funds and 12 of 68 funds.)

     Our barbell strategy (a balance of longer and shorter securities) 
continues to be successful.

     The Tax-Exempt Money Market Fund has, of late, been marked by two main 
characteristics--a voracious appetite for paper and low issuance. Tax-free 
money market funds continue to bring in assets, although the pace has 
recently slowed. Unfortunately for hungry buyers, issuance of short-term 
tax-exempt securities has been low. Note, issuance has been low for several 
years now, due to the improved economic health of states and municipalities. 
Variable-rate issuance is dropping because low long-term interest rates and a 
flat yield curve make locking in low long-term rates more appealing to 
issuers than playing the variable rate game. These factors obviously conspire 
to keep yields low.

     So what is the SAFECO Tax-Free Money Market Fund doing in this 
environment? Our barbell strategy, as I mentioned before, lives on, and 
continues to work well for us. As of quarter end, we had 63% of the Fund's 
assets invested in variable rate demand options, 29% in put bonds, and 4% 
each in notes and commercial

paper. This represents a 3% increase in puts and a corresponding decrease in 
variable rate securities and notes. There is no master plan behind the 
change, and it merely represents cyclical factors in cash flows and the 
market in general.

     My outlook for the market (keeping in mind that I have no ability 
whatsoever to predict the future) consists mainly of seeing no indication 
that there will be any change any time soon. There is no reason to think cash 
inflows will dwindle to a halt or that issuers will start issuing with wild 
abandon.

                            NOTES TO FINANCIAL STATEMENTS

1.   GENERAL
     This financial report is on 11 of the SAFECO Mutual Funds. Each Fund is a
series of one of the following trusts listed below. Each trust is registered
under the Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company.
      
     SAFECO Taxable Bond Trust
          SAFECO Intermediate-Term U.S. Treasury Fund
          SAFECO GNMA Fund
          SAFECO High-Yield Bond Fund
   
     SAFECO Managed Bond Trust
          SAFECO Managed Bond Fund
   
     SAFECO Tax-Exempt Bond Trust
          SAFECO California Tax-Free Income Fund
          SAFECO Municipal Bond Fund
          SAFECO Washington State Municipal Bond Fund
          SAFECO Intermediate-Term Municipal Bond Fund
          SAFECO Insured Municipal Bond Fund
     
     SAFECO Money Market Trust
          SAFECO Money Market Fund
          SAFECO Tax-Free Money Market Fund
     
     Effective September 30, 1996, the Intermediate-Term U.S. Treasury, Managed
Bond, California Tax-Free Income, Municipal Bond, Washington State Municipal
Bond, and Money Market Funds began issuing two new classes of shares -- Class A
and Class B shares (collectively, "Advisor Classes"). Effective January 31,
1997, the High-Yield Bond Fund also began issuing Advisor Classes. Unlike the
no-load class of shares (which are sold directly to the shareholder with no
associated sales and distribution charges), these new classes of shares are sold
by financial advisors to shareholders and have associated sales and distribution
charges.  Each class of shares represents an interest in the net assets of the
fund.

     In connection with issuing the new Advisor Classes, all of the
above-mentioned funds (except the Money Market Fund) adopted a Plan of
Distribution ("the Plan").  Under the Plan, each Advisor Class pays the
distributor, SAFECO Securities Corp., 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 each Fund in the preparation of its financial statements. Policies
are in conformity with generally accepted accounting principles, which permits
management to make certain estimates and assumptions at the date of the
financial statements.

     SECURITY VALUATION. 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. 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. Other temporary investments
purchased at par are valued at cost.

     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 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. Bond premiums and original issue discounts are
amortized to either call or maturity dates. In the Tax-Exempt Bond Trust,

market discount on bonds purchased after April 30, 1993 is recorded as taxable
income at disposition. Interest is accrued on bonds and temporary investments
daily. The Managed Bond Fund has elected to amortize premiums on securities
purchased above par value. The funds in the Taxable Bond Trust have not elected
to amortize premiums on securities purchased above par value.

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Net investment income is
declared as a dividend to shareholders of record as of the close of each
business day and payment is made as of the last business day of each month. Net
gains realized from security transactions, if any, are normally distributed to
shareholders at the end of December.

     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 funds in the Tax-Exempt
Bond Trust and the Tax-Free Money Market Fund intend 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.
